The new V2 firmware for the Algoforce included a change around coil calibration, in past versions an out of spec coil would fail calibration, basically saying the coil needs calibrated, usually for ultra fine mode however you could still manually select and use ultra fine mode for detecting, albeit sub optimally and you would likely be better off using it in fine mode where it did calibrate for best results. Since V2 the modes that don't calibrate have been blocked from use and you can no longer select them on an out of spec coil, this has bought to light just how many out of spec coils are floating around out there. Common offenders are the older Detech coils, especially the smaller coils and the two Nugget Finder Sadie coils, the original and the Mk2, I've noticed a number of people with the Sadies and the problem and the Nugget Finder 12x8" EVO is also hit and miss although I'm sure there are more. I would assume this is something to do with being hand wound coils and just not getting it perfectly right every single time. With the Detech coils they're generally really old coils people are using and I'm not sure if that's something to do with it, coils going out of spec over time or just out of spec from the start? All of this went unnoticed on the earlier GPX series. Some people have been upset that in the older firmware they were using ultra fine with their coil and now they can't with the new firmware, the idea of blocking out the out of spec coils from using modes they don't calibrate in was because they were not going to work properly in that mode so using ultra fine with a coil that won't calibrate is more like a placebo, it makes you feel good you're in ultra fine but you're not benefitting from doing so. The coil calibration algorithm in the v2 firmware is the exact same as in the previous firmware so both would have the same results with pass/fail on coils, the only difference being version 2 blocks the sub optimal coils using the modes they won't work well in. Here are some examples of the discussion around it the past couple of days with people having these problems. One person thinks their Sadie MK2 is a Coiltek coil, mistake on their part there. The good news is it looks like Nugget Finder or at least the dealer replaced the out of spec MK2 Sadie for a customer and he got a working replacement, this seems the best path forward on coils that are under warranty still if the dealers/manufacturer will replace them, I'm sure Coiltek will if the problem pops up for their coils as they advertise them for the Algoforce although I've never seen one of their coils having the problem. Where the guy in the original post says his ground balance numbers disappear, this behaviour is normal he's just only new to the detector, after 3 seconds the ground balance numbers do go away after performing a ground balance.

I sent Alex some general questions about coils and connections. First, while damage is unlikely, the detector should not be powered on without a coil attached. Also, coils should not be connected or disconnected while the detector is powered up. The E1500 is designed specifically for the use of mono coils and is wired to run one winding as both transmit and receive coil - the definition of a mono coil. A DD coil may be attached to the E1500 and it will normally operate but with only one half the coil active. One half of the DD coil will act as a mono coil, and the other half will simply remain an open circuit. The is identical to what happens with Minelab GP and GPX models when you run a DD coil in mono mode. From the GPX 5000 manual: "Using a Double D coil, running in Mono will often increase the sensitivity of the detector but may also be a little more unstable in heavily mineralised ground. Pinpointing is not centred in the middle of the coil, but to the left side, and may give a complex signal when the target is very close to the coil. It is recommended you use the left edge of the coil to pinpoint shallow targets." To clarify, when they say that the detector may be more unstable in heavily mineralized ground, they mean compered to the DD coil being run in DD mode. Running it in mono mode turns the coil into a smaller, hotter mono coil, which not only increases it's sensitivity to small gold but also ground and hot rock effects. Alex emphasized that they did no testing with DD coils but that there is no problem giving them a try. This raises interesting possibilities for people who own a DD coil and want to try it. For instance, a Minelab Commander 10" x 5" DD coil would be transformed into a roughly 10" x 3" mono coil if attached to the E1500. It would obviously still be the same physical size and weight, but also might be a very sharp small gold coil that would cover a decent swath of ground. As the DD coils get larger you would be paying a significant size and weight penalty, but on 11" and smaller coils they are light enough already it should not pose an issue. And mind you, I am not recommending people run out and get DD coils to do this. It is just that there are a lot of these coils out there sitting unused and perhaps a E1500 user will already have one, or get one dirt cheap to play with. Good article here by forum member Nenad (phasetech) on mono and DD coil differences. Algoforce E1500 Specifications & Manuals Double D (DD) coil in both DD mode and Mono mode

Good news, a new firmware is ready to roll. Release Note for Software V2.0.0 Release Date: 08/05/2025 At AlgoForce, we are deeply committed to continually investing in research and development to enhance the performance and user experience of our detectors. We proudly provide these improvements to our customers through free software upgrades — and we’ve done it again. Just like smartphones and other advanced electronic products that require continual software upgrades to unlock new features, improve performance, and enhance user experience, the E1500 series also evolves through ongoing software development. This ensures your detector remains at the cutting edge without the need to buy new hardware. Version 2.0.0 represents the most significant update to the detector’s interface and usability since the launch of the E1500. It is highly recommended that all E1500 and E1500 Plus users upgrade to take full advantage of the new features and improvements. What’s New • Dual User Modes: Standard & Advanced This version introduces two selectable user modes to better suit different experience levels. Users can seamlessly switch between modes to match their detecting style and skill level. Standard Mode simplifies the interface for beginners, focusing on ease of use. Advanced Mode provides greater control and customisation for experienced users. • Improved Menu Layout & Navigation Menus have been reorganised for more intuitive navigation. • Enhanced Visual Feedback Updates to on-screen messaging improve clarity and usability, enhancing overall interaction with the detector. Note: · Please refer to the Software Upgrade Instructions on page 23 of the user manual to perform the software upgrade. · After upgrading from an older version, any customised coil size settings and coil calibration data will be reset. Once the upgrade is complete, be sure to calibrate the coil as you would with a new detector by following on-screen instructions under Calibrate Coil in Standard User Mode or Coil Selection in Advanced User Mode. You can download it here: https://cdn.shopify.com/s/files/1/0793/5416/7570/files/AlgoForce_E1500Plus_software_V200.bin?v=1746620816 Also, for those with a Mac, you'll notice the Mac Firmware upgrade tool is coming soon on their website, Downloads – AlgoForce Pty Ltd until then, it's borrow a friends computer. Here are some photos of the screen with the new firmware, ignore my dodgy install of a screen protector 🙂 I've never been good putting them on. New user mode selection screen, default is the basic mode, and after firmware install it will be in basic mode wanting to calibrate the attached coil. You just go left for basic, right for advanced. Doing a noise cancel. Detect mode screen on the Large Gold setting where you can select between 3 pulse delays, helps if you want to cut out detecting pellets and only find bigger stuff to go to Pulse Delay 3. My favourite Ultra fine mode. Volume is top left of the screen, its on 2 at the moment as I'm just at home, backlight is the 0 on the right. This screen works very well in the sun so you have the backlight off generally unless you're on a very cloudy day or night time. The soil types screen, I stick to Low Mineral here, mostly others will be on the left for Mineralized soils when looking for gold, unless they're lucky. The default soil mode, hot! Lucky last is beach mode. The Calibrate coil screen, easy to do just follow the instructions on screen. This is in mild mode, you'll see there is no ground drift down the bottom of the screen, valuable real estate too so hopefully Algoforce can come up with something to put there to benefit mild soil users. There is a G up near the numbers at the top now, the reason is people were confusing this with Target ID which is only in Pinpoint mode, it's the ground phase number. A photo in mineralised mode, showing the Ground drift, my ground doesn't drift here so the bars don't move but they extend outwards indicating when you need to ground balance, the bigger they grow the more you need to think about doing a ground balance. Here is me attempting a ground balance but as I'm in mild mode, there is no GB required as GB is disabled, although I never really need to balance in my soils around here anyway. And the new coil selection screen, it's been modified a bit to be more descriptive, and the default selection of coils has changed to more suit the available coils on the market currently, these can be edited to describe your own size coils, the Coiltek 10x5" now leads the list. A good default selection though. Connected is my 10" spiral X-coil so I'll edit a slot to take it soon, likely the 8x6" as I'll likely never use my Sadie and will use the other sizes pre-configured. This is going over a target in detect mode. And pinpoint mode with Target ID, this is in 100 tones pinpoint mode, once I get over the target I'll get the arrows on the bullseye and the most reliable target ID. This is near to a target, but not centered on it. This is a different target and I'm centered on a target, note the arrows up the top on the bulleye. This one is done in 5 tones pinpoint mode. I think this firmware will be much easier for beginners to use and understand, and still the advanced users are not cut out as they have all the features they always had with an improved interface.

I found this interesting, a Turkish coil manufacturer has made an 85" cm coil for the Algoforce and seems happy with the results for use in artifact and treasure hunting in Europe. These type of people hunt for long hours looking for large deep objects and they seem quite happy with the Algoforce for the purpose, I guess it would be very light compared to something like a GPX 5000 and appears to be doing well with depth. 180cm depth on 20*20 copper metal 120cm depth on 10*10 nickel.. And an air test video When he asked me if the Algoforce would be suitable for this task I said no, turns out I was wrong, he's very happy with it for the purpose and now wants to become a dealer for Türkiye likely bundling it with his giant coils.

A friend without Youtube filmed this video so I'm putting it up for him, he was playing around with his Algoforce and comparing it to the GPX 6000 and Manticore in some black salty sand and he did a good demonstration of how well the Algoforce can handle these difficult conditions that the GPX 6000 cannot handle at all. He's using a MK2 Sadie in the video, you can make it work even better and deeper with a less sensitive coil. I've had good results in my testing with the 11" Commander Mono in this sort of situation. I've never understood when someone says the GPX 6000 handles tough conditions well, just because the packaging says all gold, all soils, all the time doesn't mean it's true 🙂 The older GPX models were much better in very tough ground like this black sand. I've seen the same results as in this video around here, the 6000 fails badly in tough black sand conditions where the earlier GPX 4500/5000 worked much better and as you can see in this video the Algoforce also does very well and can even accurately Target ID accurately in the black sand. The GPX 6000 also fails in hot rocks around here that the Algoforce handles well. We have some of the worst black sand in the world in NZ at some of our West Coast beaches, I'm yet to take my Algo to the worst pure black sand beaches but the mixed sand and black sand beaches I've tried so far, it's worked remarkably well. I hope to get a chance to go to some of the really bad beaches soon as I'll have a good advantage over the previous attempts by people to detect them, I think, the Tarsacci that was touted as handling our beaches was a massive failure and didn't work well at all, I expect the Algo is going to do much better from what I've seen so far. I'll get some video when I make it to a good black sand beach showing how I go.

I don't know if anyone will find this interesting or not, I personally don't as my soils very different and I don't know how the conditions in this area would relate to my own but it was good to see the difference between the NF EVO and 14"x9" Elite. It just refuses to hit that 18" target at the end, I would have liked to see another detector in the mix to see how it went on that target, a 6000 or 5000 would have been nice to see, I'm sure the 5000 would be all over it.

I've got two batteries for my Algoforce so far, both work great but I've discovered they make battery banks for a tough life, and well, at least for me that's hanging off the bottom of my metal detector and seeing I like my Algo so much I'm going to treat it to a tough battery Dark Energy Poseidon PRO Power Bank Portable Charger Kit - Survival Supplies Australia It's about double the price of a normal one, if not more, but it's made for the outdoors even being waterproof IP68 Poseidon Pro – Dark Energy It claims to hold a charge for 8 years. The video is funny, they blow it up, shoot it, drown it, you name it and it survives.... and all this and it's significantly cheaper than a Minelab battery ?

I find the speculation that the E1500 will somehow outperform detectors costing much more money to be, well, how to put this nicely… questionable at best. If this detector was GPX 6000 class it would be stupid to sell it for one quarter the price of a GPX 6000. I don’t think Alex is stupid. Here is the current price structure in Australia (U.S. prices at bottom) as of today after Garrett just introduced the lower priced stripped down Axiom package: 1. Minelab GPZ 7000 $10,499 2. Minelab GPX 6000 $8,999 with two coils 3. Minelab SDC 2300 $4,399 4. Garrett Axiom $4,399 with one coil (Axiom Lite) 5. Algoforce E1500 with Sadie & Battery $2649 6. Minelab Manticore $2499 7. Minelab Gold Monster $1299 From my use of the E1500 I think that you are going to get what you pay for. The E1500 is a very affordable option at close to the price of a top end VLF and will outperform said VLFs on gold in mineralized ground. I think the E1500 falls short of SDC 2300 and Axiom level performance, essentially being a bridge between VLF detectors and those models. The 6000 and 7000 continues to rule the roost but at twice the price of the SDC/Axiom level you are not getting twice the depth. Pulling a number out of my posterior I’d assign a very debatable expectation of about a 15% increase in overall performance at each major step up in price. People can of course argue that number all day long but I think it is very important to give newbies some sense of reality. Twice the money does not get twice the performance. Gains are more like 10% - 15% - 20%…. pick your number, but it’s not double, triple, quadruple. If I was still selling detectors I’d explain to this new customer that they can go find a gold nugget with a Gold Monster or a Manticore. I’d explain that for not much more than a Manticore they could get an AlgoForce E1500 and be able to deal with mineralized ground and hot rocks that will give the VLF models real trouble. I’d tell them that for substantially more money they could get some very solid bang for the buck in the Axiom/SDC range, a step up from E1500 but still not top tier. Finally, I’d tell them that if money is no object and they simply want the best performance they can get, to look at the 6000 or 7000. I’d comment that out of the box with provided coils the 6000 would have the edge for smaller gold, and the 7000 the edge on larger gold. Adding aftermarket coils (and more money) to the 7000 can close the gap between it and the 6000 on small gold, but nothing you do to the 6000 will have it hitting the big stuff as deep as the 7000. That would be my short and sweet sales presentation and I offer it up as the most simplified big picture no B.S. look at the scene as you are likely to find. My somewhat educated opinions only, feel free to toss in trash bin if you don’t agree. In the States this is the situation as of 2/19/2025 1. Minelab GPZ 7000 $9,499 2. Minelab GPX 6000 $6,999 with two coils 3. Minelab SDC 2300 $3,699 4. Garrett Axiom $1,999 with one coil (Axiom Lite) 5. Algoforce E1500 with no battery or coil $1650 (figure about $2000 at least once battery and coil added) 6. Minelab Manticore $1,799 7. Minelab Gold Monster $849 8. Garrett 24K $679

A friend without Youtube filmed this video so I've uploaded it for him, he was experimenting with the Target ID feature on the Algoforce, it's a good demonstration of how they work.

Not my video

I'm only new to the SDC having just got one, although it doesn't take a rocket scientist to use it 🙂 I find it quite a nice detector to use, I don't find its ergonomics bad at all, a little awkward with the coil the way it is but nothing that I wouldn't get used to, it feels quite light, obviously not near as light as an Algoforce but nothing I'd be worried about weight wise. I love how it folds up and will be taking advantage of that to put in a backpack to take places I wouldn't normally bother taking a detector due to the effort involved. Some may wonder why I don't bury the little jars, firstly, it's a waste of my time, these types of nuggets are found so close to the surface with both detectors and normally only found in shallow bedrock areas it's just not worth my time, and in my mild soils what I see in the air is what I see in the ground, there is very little difference if any on the inground and above ground results, with my soils being so mild. All I care about is outright performance, and the one that does best, as my inground results always mirror that. So far initial impressions are the Algoforce is slightly more sensitive to small gold even with both running a bundle wound coil, I'm yet to compare using a spiral on the Algoforce. It also benefits from having more settings such as for me the mild soil mode which gives it a bit of a boost over the SDC that's fixed in its timings. I hadn't used the SDC prior to this morning as we haven't had idea weather, now a big high has come over and it is becoming fine, our big high is pushing that cyclone over Brisbane which isn't good. Anyway, I made a mad dash down to the river behind my house this morning to compare the SDC to the Algo on some small nuggets, all in the 0.2 and under size, maybe the biggest one might be .4 and the smallest 0.03 , really can't remember most of their sizes as they're just recent finds I put into little tubs. To be fair on the SDC I used a bundle wound 10x6" coil on the Algoforce as it was the closest coil I had to the 8" round bundle coil on the SDC, I can't help but think if I left my 10" Spiral on the Algoforce the gap between the two detectors would grow quite a bit and the SDC would be left behind, that's something for another day. I was happy with the performance of the SDC, I found it very similar to the Algoforce with estimated depths on the nuggets with a slight edge to the Algoforce across the board I think, and that increased a bit when I switched to the mild soil mode on the Algoforce which lucky for me I can hunt in around here so for me at least, I'd prefer to take the Algoforce on a hunt than the SDC, in saying that I'm sure in different environments the SDC would be the most beneficial with its tracking and potentially better soil handling, I'm no expert on mineralized soils by any means so really don't know performance differences in that scenario, hot rocks are my issue and both the SDC and Algo so far appear to handle them similarly although the SDC doesn't see some at all that the Algo needed to balance over. Anyway, I did this little bit of a run over these nuggets for my own benefit so I could see how the difference was between them, you're seeing it as I saw it, I had not done the test before I started filming and had no idea what the results would be. I quite like the SDC so far, a pleasant surprise.

Hi Guys, Happy Australia Day!! Kind of cool to have another Aussie developed PI raising some eyebrows today. I should start by saying that unfortunately, FCC testing has not been done yet, so the product cannot be sold to the US at this point in time. But is available to NZ customers - so ignore my email Simon ? I have done a little testing on the E1500, and a few of my features/suggestions were added in, but the detector was already quite developed when I was approached for some feedback. There was a software update and then the user manual needed to be updated to include the changes. I've only had limited time on the latest version, but here's some info that will get you up to speed a little bit. 1. First of all, performance wise, this thing sits between a Gold Monster/Gold Kruzer and SDC2300. It is extremely sensitive to tiny targets, but depth won't match a 5000/6000 on large targets. I think the SDC2300 will remain superior in really bad soil conditions, but the E1500 is quite adjustable (broad sensitivity range), and obviously with different coil options, e.g. round/elliptical/semi-elliptical and flat wound/bundle wound, you can kind of dictate the performance a little bit. 2. It is for mono coils only, but works very well. Coil calibration feature is a nice touch, and optimises the electronics for any slight variations between coils. It will also tell you if you need to calibrate or not. 3. Current wise it draws about 700 ma on average, so a 10 AH power bank should run for about 13-14 hrs. Great for guys hiking into remote spots with no power. Just carry three power banks and you're good to go for days. 4. Tested on a 0.05g bit of gold and the E1500 was better than a 4500. With a Sadie coil it is super sensitive, and the tone modulation is very sharp. With an older Minelab 11" super gold search coil, depth is improved, but signal sharpness is not as good, but runs extremely stable. The 14x9" Evo seems to be a great coil for it. I think a Detech 8" mono, Minelab 8" Mono and NF 12x7" Advantage would be the pick of the coils for really hot ground, as they are bundle wound. Possibly add in the old Coiltek 11" round terracotta, and Minelab Commander and earlier Super Gold Search. But in average mineralised conditions, the Evo coils work great. 5. Hotrocks. A 6000 with 11" Mono is a little more immune to hotrocks than the E1500 with Sadie coil in Ultra Fine timing. With a slower timing, and larger coil, hot rocks are far less detectable as you'd expect. But, being a PI it is vastly superior to a VLF. 6. The shaft and hand grip feel great. 2 arm strap sizes is excellent and should cater for most people. 7. Buttons feel really nice. They have a very positive click about them. 8. The Auto ground balance works great, but is on the slower side. Slower than 4500. This is a ground balance reset only, i.e. after it has ground balanced, the ground balance is locked - just like a GP/GPX machine in Fixed. It is not continuously tracking like the SDC2300 or 6000. However, you can see when the ground balance is going out with the Ground Drift function - so it is sort of tracking in the background, but it's up to the user to reset it. 9. Interference with other detectors - I've only been out once with another prospector who was using a GPZ7000 with a 12" NF coil. We found that I needed to be about 10 metres away, that's with a Sadie on the E1500. Any closer and the GPZ would start to pick it up. 10. The Sensitivity range is great. I expect most people are going to run it in the low 20's, but in super quiet conditions, 26-30 are kind of like boost. I've got a lot more testing I'd like to do, and still playing around with headphone options, but having independent threshold and volume controls as well as adjustable tone, it should be able to adapt to pretty much any wired or wireless options. The target ID feature was demo'd to me, and appeared to be quite stable, but I haven't played around with it much at this point. So what is? It is a very well built PI machine, with a collapsible 3 pc shaft, has the benefit of being compatible with legacy 5-pin coils, a very well thought out user interface with a simple menu, and all the important functions you need. It is not waterproof, and doesn't have built in wireless, and comes as a bare bones kit, but all these things have allowed it to be offered at an attractive price point. It is not a deep machine. If you want depth on a budget, get a S/H 4500 or 5000 with a 20" mono or 25" DD. If you want to find small gold as well as specimens and reefy gold, then the AlgoForce E1500 is worth a look. Hope that gives you a bit of a better understanding of its capabilities. Yes, I plan on doing some videos so you can see how it behaves and what it sounds like.

Video is down now. GPX-5000 & Algo teamed up with the Nugget Finder New MK-2 [Semi-Flat Wound (Rectangular)] Coil

Well, it was a bit before I was going to, and it is used instead of new, but I bit the bullet and purchased an Algoforce. Many of you probably missed it as it was only up in the Forum classifieds for a few hours but Phrunt decided to sell his Algoforce. And the price was simply too good to refuse. Sorry @PhaseTech but you missed a sale. Probably hear from me shortly re: a Quest Wire Free Mate though 😉 I wanted something as a back-up detector for the 5000 and also something for friends/family to use as a few of them have started getting interested. Was thinking about a new Algo or waiting to see what the Nokta PI might be like but was swaying towards the Algo with the easy battery options and being able to use GPX coils I already have. So, I took it out for 1.5 hrs last evening for a little trial with the Sadie MK2. Went to a little area that I generally test new detectors when looking at what their 'tiny nugget' capabilities are. Found 3 bits, a tiny piece of lead shot, a few bits of tin, etc. 1 target that ended up being gold was actually a target that I knew was there and had left for a mate to see if he could hear it with his Gold Monster, but he's become disinterested in detecting. Originally had been found with the 6000 and the 11" mono. I had tried that piece with the modded 5000 in its 'smallest' setting and the MK2 Sadie and it couldn't hear it. The Algo heard it no worries at all which sort of did and didn't surprise me. It is designed for small gold so it makes sense, but I've also found some tiny bits with the 5000. Different gold make-up maybe? Settings were pretty easy and straight forward. I need to read up a bit more about the noise cancel and how to do it most effectively. Mostly ran about 25 Sensitivity. 27 was too much and 23 was a dead flat Threshold. Feels like a sturdy construction, obviously finds the tiny bits and should be really easy for family/friends to pick up and use knowing that they are a genuine chance of finding some yellow. Having been a QED owner I can't help but think this is the sort of final product that Howard was aiming for? A lightweight, easy to use, good value PI for the general hobbiest fossicker/prospector. Probably try the 12" round EVO next and will also put on the NF 11X7 Advantage that didn't seem to work well at all on the 5000 and see if it calibrates. Bit more learning and trial and error yet but thus far quite pleased with the purchase. Oh and P.S. - this is an original E1500 with a few of the newer bits blinged on. However, the speaker is the original and it is the only complaint I have so far - it is terrible. With a Quest and earbuds it will be fine but it is a shame they made it out of the design stage with such a poor speaker set-up.

I found this video interesting; I don't experience a lot of hot soil so it was good to see it in action on this ground. The guys just got an Algoforce and is doing his initial prospecting with it on old hunted out ground, while some stuff is a bit questionable like he found 3 pellets and said the 6000 missed them when it's very unlikely it did, more like he missed them 🙂 It's worth a watch for someone that's never seen the Algo in action on hotter ground, and also he shows the 00 on pellets and also a good demonstration of why you can't 100% rely on that as he finds a small specimen that's reading as 00 too. You would only use the 00 as a discrimination method in ground that's got a lot of pellets to help make dig decisions, not an area with 3 pellets and a history of plenty of gold. I found it interesting when he said he's tried the Sadie MK2 and Joey on it, I've got the Joey and tried it out and found it similar to the first version Sadie, I figured the second version would be better.

Seems to be a ton of interest in it for sure. I plan on getting one, once the pros in the US have time to evaluate and report on it.

Firstly, the new firmware changes. Software V1.1.3 includes the following updates and improvements: 1. Enhanced Display Theme Switching: Previously, switching between dark and light display themes was only possible through the Miscellaneous settings menu. Now, users can switch display themes from anywhere by holding the Backlight/Theme button, providing greater convenience and ease of use. 2. New Audio Settings in Pinpoint Mode: Added 5 Tones Inv. and 100 Tones Inv. audio settings, offering an alternative feedback option. These settings take advantage of human sensitivity to high-pitched sounds to better target identification: 5 Tones and 100 Tones: Best for identifying highly conductive targets with higher target IDs. 5 Tones Inv. and 100 Tones Inv.: Ideal for detecting small items, such as gold nuggets, with lower target IDs, as higher-pitched tones are used to highlight these signals. _______________________ Something others may also be interested in, the E1500 plus is AVAILABLE in the UNITED STATES We are excited to announce the release of the E1500 Plus, our latest addition to the E1500 series, alongside the launch of Software Version 1.1.3.

And yet another video pops!

A friend recorded these videos, he doesn't have Youtube but I thought they were quite good videos and show the benefits of having a machine that handles EMI very well, which is the Algoforce. I found the SDC comparisons particularly interesting as the SDC is the Minelab PI detector I know the least about, never even turned one on. The first video is about EMI handling and how the detector performs on some small gold within the high EMI environment Here is his Part 2, which he compares the GPX 6000, SDC 2300 and Algoforce on some small gold, I found the SDC results particularly interesting, I've heard a lot of people say the Algoforce easily outperforms the SDC, it appears so in this video. I've never used an SDC so my knowledge on it is extremely limited.

NOTICE - Announcing AlgoForce E1500 Software Update V1.1.2 Software Version 1.1.2 was released on 23/08/2024. The v1.1.2 software update introduces Pulse Delay Options for Large Detection Mode, allowing users to optimize detection for various object sizes and reduce mineralization noise. It includes three Pulse Delay settings: Pulse Delay 1 (maintains previous performance), Pulse Delay 2 (filters very small objects), and Pulse Delay 3 (focuses on larger items). Additional updates feature a new settings menu access method, an independent pinpoint sensitivity setting, an optimized pinpoint user interface, and adjusted target ID mapping. These enhancements improve detection accuracy, stability, and user experience. What's New in v1.1.2? 1. Introduction of Pulse Delay Options for Large Detection Mode 1.1 What is Pulse Delay? The Pulse Delay Options allow users to select the time delay between the transmitted pulse and the reception of the return signal. After the primary pulse is transmitted, the detector waits for a short period before it starts to listen for the secondary pulse generated by the metal object. This waiting period is known as the pulse delay. Shorter Delay: Detects weaker signals from smaller objects. Longer Delay: Filters out signals from small, less conductive objects, focusing on larger items. Reduces mineralization noise in high mineralization areas for more stable and accurate detection. 1.2 Pulse Delay Options: Large (Pulse Delay 1): Maintains the performance of the Large Detection Mode in previous software versions. Large (Pulse Delay 2): Filters out signals from very small objects, focusing on larger items. Audio response is rounded and elongated. Large (Pulse Delay 3): Filters out signals from small objects, focusing on larger items. Audio response is rounded and elongated. Note: Large (Pulse Delay 2) and Large (Pulse Delay 3) can be used to ignore small lead pellets for nugget detecting or small foils for beach detecting. 2. Additional Updates in v1.1.2 2.1 Settings Menu Access To access the settings menu, briefly press the Return/Auto Frequency Scan Button in the Main Detection UI instead of the Right/Auto Ground Balance Button used in previous versions. To exit the settings menu, press the Return/Auto Frequency Scan Button again. This change prevents users from accidentally entering the settings menu when attempting to perform Auto Ground Balance. 2.2 Independent Pinpoint Sensitivity Setting An independent pinpoint sensitivity setting enables precise tuning specifically for pinpointing metal objects without affecting the main detection sensitivity. This separation ensures that while the main detection sensitivity is set for general detection, the pinpoint sensitivity can be finely adjusted for the accurate location of metal targets. 2.3 Optimized Pinpoint User Interface In Pinpoint mode, the detector now tracks the target signal peak. When the target signal reaches 90% of this peak, the pinpoint icon on the top center of the LCD screen will flash, helping users center on targets more efficiently. If the coil is moved off the target and the signal volume decreases, the flashing stops. Moving back over the target resumes the flashing. As in previous software releases, pressing the Left/Pinpoint Button retunes the detection threshold due to ground variation or temperature drift. In v1.1.2, pressing this button also resets the target signal peak to zero. 2.4 Adjusted Target ID Mapping Software version v1.1.2 restores the high target ID resolution for small targets that was slightly reduced in v1.1.1 compared to v1.1.0 and earlier versions. With target ID mapping based on the Ultra-Fine detection mode in v1.1.0, it delivers high resolution for small targets, helping users distinguish between lead pellets and small gold nuggets. Additionally, v1.1.2 ensures consistent target IDs across various soil types, detection modes, and pulse delay options. Please follow the Software Upgrade Instructions on page 16 of the user manual to upgrade the software. You can also watch Simon's demonstration on YouTube. IMPORTANT: After the software upgrade, it is crucial to perform a factory reset. You can download it, along with the new manual to suit here

For those of you that have had the chance to run both, how would you compare them for gold ?

Algoforce is an ever-evolving detector, the Algoforce team are constantly improving it and the latest firmware is no exception. This one is something those of us that have mild soil parks and fields are really going to appreciate, along with those that intend to use the unit as a beach detector, it has a new ZeroGB mode that adds significant depth in milder soils, and a new beach mode that uses the same ZeroGB method to enhance beach detecting depth while ignoring the salt even with the coil submerged in salt water. I really like this new update; it benefits me a lot with my coin and jewellery detecting. The detector has evolved from a gold only machine to a very capable coin and jewellery detector for parks and beaches, and by having Target ID it makes that even better than you would think with a PI. I did a really basic video when I first tried it out by using my Algoforce on 16 sensitivity seeing I was in my front yard which has a lot of EMI, the maximum sensitivity is 30, the coin is a New Zealand $1 coin, and the buried depth is approximately 20 to 25 cm, 8 to 10 inches and I'm only using a little 10x6" bundle wound mono X-coil. I really have no idea how deep the coin is now as it's been there for years but it was initially buried about 20cm so I'm estimating 25 as with the soils here coins sink and sink deep. The Length of a pinpointer is about the average depth I find coins, some deeper especially the UK copper penny's which are quite large coins and tend to sink deeper. The depth of the coin doesn't overly matter for the video as the video demonstrates the difference when you're in mild soils and can switch into the new Mild soil ZeroGB mode. You'll note the pinpoint mode also benefits from the extra depth in mild soil mode, prior to switching to that mode I was unable to get a pinpoint target ID, after switching to ZeroGB the Target ID kicks in. Here's the quick video I did just after installing the firmware to try it out and see the depth increase myself. The detectors also had a hardware change to a new version 2 of the basic package with a new shaft and arm cuff with comfort cover and stand with a new battery holding method that improves upon the original release, I didn't personally find anything wrong with the original shaft package but the improved one seems great with enhancements over the original, I did point out the USA customers are going to get a very well refined unit by the time it reaches the USA market, as it's evolving quickly. You can see more on their website at www.algoforce.com.au Here is the information off their website Our team has been continuously working on improving the AlgoForce E1500. We have been developing new software with enhanced features to unlock its potential, and simultaneously designing a new shaft to further enhance its overall convenience and usability. We are excited to announce that the AlgoForce E1500 Basic Package has evolved from version 1 to version 2. Equipped with the new shaft, the E1500 Basic Package version 2 includes several improvements: a fixed coil yoke, a stable middle shaft, a protected USB cable with a right-angle connector, lighter weight, increased full extension length, and the same compact length as version 1. These enhancements boost both convenience and performance. For further details about the differences between version 1 and version 2, please refer to the product page and page 7 of the user manual. Additionally, we are releasing version 1.1.1 of our AlgoForce E1500 software. This update introduces the highly anticipated Soil Type Setting, allowing users to select between Mineralised, Mild, and Beach options to optimise detector performance in various environments. Other enhancements include increased backlight brightness, an optimised pinpoint user interface, and adjusted target ID mapping for greater consistency. What's New in V1.1.1? 1. Introduction of Soil Type Setting 1.1 What is the Soil Type Setting? The Soil Type Setting allows users to select the appropriate soil type for their detecting environment, optimising the detector's performance. The available soil types are Mineralised, Mild, and Beach. 1.2 Soil Type Options: Mineralised: This option maintains the performance of previous software versions, suitable for mineralised soils. Mild: This option utilises AlgoForce's ZeroGB technology, which disables ground balance to enhance sensitivity for nuggets, coins, and treasures of all sizes in extremely mild gold fields, parks, and fields. Users do not need to perform ground balance when using the Mild option. If the soil mineralisation indicator reads 00 or 01 when you pump the coil up and down, you can try the Mild option. However, if selecting the Mild option reduces sensitivity by 4 or more compared to the Mineralised soil type with proper ground balance, it is not suitable for the soil. In that case, please select the Mineralised soil type. Beach: This option also uses AlgoForce's ZeroGB technology, yet aggressively rejects seawater signals and provides smooth operation on dry sand, wet sand, and even with the coil submerged in seawater. This option offers high sensitivity to coins and treasures commonly found on beaches without the need for the user to perform ground balance. 2. Additional Updates in V1.1.1 2.1 Increased Backlight Brightness: Enhanced visibility with a brighter backlight. 2.2 Optimised Pinpoint User Interface: The target ID is now displayed in a larger font for better clarity and positioned separately from the mineralisation ID to avoid confusion. 2.3 Adjusted Target ID Mapping: Improved consistency of target IDs across different detection modes, regardless of which soil type is selected. Please follow the Software Upgrade Instructions on page 16 of the user manual to upgrade the software. You can also watch Simon's demonstration on YouTube. IMPORTANT: After the software upgrade, it is crucial to perform a factory reset.

We have a new player on the field in the form of AlgoForce and their new E1500 detector. One thing that is not getting as much attention as I would expect from a PI - full range target conductivity id. From the owners manual: "For experienced PI users accustomed to estimating nugget size from audio cues, the AlgoForce E1500 can also help to estimate size or conductivity through its stable conductive target ID (0-99), even in highly mineralized soils. High single frequency VLF detectors typically struggle with signals on wet ocean sand, where PI detectors are far more capable of detecting through the salt mineralization. Capitalizing on its UltraFine pulse induction technology and stable conductive target ID (0-99), the AlgoForce E1500 excels on the beach, proving to be a versatile tool for searching fine jewelry, coins, rings, and other treasures." (Emphasis added) The discrimination feature kicks in when using the pinpoint mode. Again, from the manual: VIII. Pinpoint detected target (if needed) Enter the Pinpoint UI by pressing the Left/Pinpoint button in the Main Detection UI. In the Pinpoint UI, adjust Sensitivity with the Minus or Plus button. To retune the detection threshold due to ground variation or temperature drift, press the Left/Pinpoint button as needed. Perform Auto GB if needed by holding the Right/Auto GB button. Return to the Main Detection UI by pressing the Return/Auto FS button. Pinpoint is a non-motion mode where the coil doesn't have to move to indicate a target. The detection signal gets stronger as the coil approaches the target, causing the audio (if audio output is on) or vibration (if vibration mode is on) to intensify. The Conductive Target ID (0-99) displayed in the Pinpoint UI remains stable even in highly mineralized soils. A higher number indicates a larger or more conductive target. To obtain an accurate target ID, it is recommended to follow these steps: Move the coil away from but close to the target. Ensure the coil is resting on the ground surface and press the Left/Pinpoint button to retune. After that, slide the coil on the ground surface until the target is positioned just below the center of the coil. The target ID is also useful for assessing the target's shape. If the target ID fluctuates significantly when the coil is moved slightly off but still above the target, it likely indicates an irregularly shaped target, such as a bottle cap or a nail with a large head. Target conductivity is not the same as VLF discrimination in that both ferrous and non-ferrous are conductive. Stuff that is small or low conductive reads low numbers and stuff that is large or high conductive reads high numbers. Ferrous can read anywhere depending on various factors, so the usefulness of the system largely depends on the nature and mix of targets you are working with. Nowhere does the AlgoForce manual refer to ferrous versus non-ferrous discrimination. It specifically refers to the Conductive Target ID - in other words, a measurement of how conductive the target is whether ferrous or non-ferrous. Most GBPI users have savvied to the fact that the high and low tones give a rough indication of target size. A hi or hi-lo tone usually means small or low conductive targets and a low or lo-hi tone usually means large or high conductive targets. You get ferrous either way, just small ferrous on one side and large ferrous on the other. However, in certain gold locations concentrating on hi or hi-lo tones only can be remarkably effective at cherry picking gold nuggets out of a nail pit. Most gold I find almost always gives a hi-lo tone. Minelab employs a method where targets blank if ferrous, and Garrett the target grunts if ferrous. The Garrett method is preset, the Minelab method can employ a variable control depending on the model. What makes the AlgoForce different is instead of the "this or that", "yes or no" answer of two categories you get a full range indication, which with experience should lead to more nuance in what can be dug and what can be ignored. How is Algoforce doing this? Imagine is instead of an unmarked variable control like Minelab offers, the control had numbers on it, from 1-100. By turning up the control you could determine at what number various items are detected or ignored. All Algoforce is doing is revealing this hidden number to you. There is no new method being employed here and if there was, you would see a patent filed for it. My best guess is Algoforce is just refining existing PI discrimination by using digital processing to refine existing methods. There is however another possibility. I will refer you to a statement by famed metal detector engineer Dave Johnson. It is part of history now only available on the Wayback machine but has been in my mind for a long time: DS: Are TID pulse units the hobby future? Or, what do you think will be the next great advancement in metal detector technology? Dave: "About 1985 I built a real sweetheart of a discriminating PI unit, not very hot in air test, but it was simple, lightweight, powered by one 9 volt “transistor battery”, ran quiet in bad ground, had no bad habits, and you didn’t have to dig any trash. It morphed into a fully static TID machine which Fisher came close to releasing about 1989, but its reliance on fully static operation which was supposed to be an advantage, was in fact a fatal flaw for a TID machine. Stripped back down, it became the Impulse which was strictly all-metals. I always wondered why Fisher did not see the obvious, that a non-motion PI discrimination methos could be used as a pinpoint mode, where non-motion is the norm. That is exactly what is going on here with Algoforce and is a defining difference between what Minelab and Garrett are doing. Their methods require the coil is in motion. The Algoforce method requires the coil stop moving, just like Dave described many years ago. Has Algoforce rediscovered and employed the same method Dave discovered? Regardless of the method employed the main difference between PI and VLF discrimination remains. The key difference between PI discrimination and VLF discrimination is it is based on signal decay instead of phase angle. This means for ferrous small items read low numbers and large ferrous items read large numbers. So imagine a normal VLF target id scale with ferrous overlaid, small to large. With PI discrimination there is basically a ferrous target possibility for every non-ferrous possibility. There is no such thing as ferrous versus non-ferrous with a PI. The best you can do is cherry pick certain locations based on the overall target mix. In some locations with small ferrous only and coins you can pretty much dig the coins while avoiding the ferrous. If there are lots of large bent nails in the ground however they read high on the PI disc scale, and will be found in the same numeric region as coins. Conversely, if you are chasing small gold nuggets, you will find that small ferrous trash overlaps with small gold. In the most simplistic sense with PI discrimination small targets have small target ID numbers and large targets have large target ID numbers. Keep in mind that from a detectors perspective a low conductive target tends to being a small target, and a high conductive target is like a large target. Perhaps it is better to talk in terms of weak targets versus strong targets. Weak ferrous and non-ferrous targets deliver lower target id numbers while strong ferrous and non-ferrous targets deliver strong target id numbers. Again, I must emphasize PI discrimination is not the same as VLF discrimination. There are different aspects to it that require a savvy operator. There are a lot of half truths and incorrect statements tossed around by people who don't know much on the subject. One of the most common claims I hear is that PI disc only works at shallow depths, and that the things you have to do to implement it give up the extra depth that is the reason for using a PI in the first place. This is based on some versions of PI discrimination and so can be true, but also reflects that the person making such statements is not well versed in all aspects of the subject. You can indeed discriminate to full depth with a PI, and in fact that is the only way I have been doing it for over 20 years now. For more details on how pulse discrimination works see my long analysis at the thread below. No, it’s not VLF discrimination, but you’d be amazed what good PI operators can do with the capability they do have. Algoforce has certainly steeped up what is possible in that regard with an affordable hand-held metal detector. We have a winner in the Under 4 Pound, Under $2000 GBPI Challenge!

Is the Algoforce actually a Dual Detector, a P.I and a VLF, if so is it simultaneous or switching from one to the other, if switching is it manual or auto.? I seem to recall at least rumors of a Dual machine that Whites was working on, but never heard anything else about it.
