I think these pictures sum up the GPX 6000 very concisely and also how I feel about those people who continue to suggest my input is biased or just marketing hype!! Tiny piece at stupid depth for its size, a typical target for a GPX 6000!! 2 Deep 2+ ounce gold content specimens retrieved at 2 feet with the standard 11” mono, both were very good signals at surface. How I’m made to feel when all the nit pickers come out of the woodwork at a product launch!!

FB GPX 6000 is showing many interesting finds including this one from Ian Butler. "GPX6000 Gold - Target about 17" deep, could get approx 10" - 12" above surface. GPX5000 in fine got response but not as defined. GPZ7000 gave less response approx 8" above ground in HY/difficult but performed better in General/difficult."

When you move the cable while it's pointed at your car you are causing the coil to wiggle and pick up the metal in the car. If it was just the cable causing the problem, it would cause the detector to sound off when the cable was moved no matter what the coil was pointed at.

Certainly possible, but difficult. All detectors operate on a frequency, and a transmitter running at the same frequency will jam it. But there are many machines running at different frequencies, and they have ability to adjust in a range. Option one would be a shotgun transmitter putting out a broad spectrum signal to jam all the range of frequencies detectors operate at. I can't imagine this working in the city as you would be jamming more than detectors, but maybe on a ranch in the middle of nowhere. You could also use a frequency scanner to locate a detector in use within range, and then have the jammer work only against that frequency, so much more targets. Still no idea on the legalities, but technically it should be possible. Cost effective? I have no clue. Simple example. Turn on a Minelab GPX 5000 in the middle of a field. Nobody will be able to get within 50 feet of that machine with another detector, as the GPX is basically throwing off it's own portable jamming field. So there is an at least 100 foot diameter circle that been effectively jammed. Expanding the concept for range is the problem though, as power requirements escalate rapidly. Kind of related. It is possible to block cell signals. It is also illegal in many places. Police jammers, same deal. Jamming is as much a legal issue as anything, and I'd cross that bridge first, before worrying about the tech aspect.

100% this! I know people out my way who kill it on gold every season with old GP extreme's. I know people out here who find bucket loads with their 45's. I also know people who find an ounce or 2 every couple of months with their 7000's and 2300's, mainly in many small bits. The whole thing for me personally boils down to if physically I can be bothered going out for a few hours. With the 7000, which I still love, I umm and argh most weekends simply due to the pain I know I am going to end up in after 3 hours. The 6000 will change that for me....Patch hunting with a decent chance of finding any sized gold, with much less agony! We did some work with machinery on one of our leases last August and I swung the 7000 for 5 days straight. It almost ended up wrapped around the nearest tree. Took 6 months before I could move my shoulders normally again 😞 For me, its a hobby. I dont want a hobby to kill me. Thats not fun at all.

You are not bringing me down at all Jason, and I never claimed you gave me any flak. Your questions are entirely reasonable, as are people’s desires to get what they perceive as totally unbiased reporting. What that means is you are the better candidate than I to be doing a bunch of critical comparative performance testing. I’ve already told you what I think, and don’t have anything to add at this time. The problem with honesty is it does not deliver the black and white answers people crave. Reality is a bit more of a bummer, in that nuance and gray areas rule. Everyone has their own set of needs, and different machines match those needs differently for different people. I’m willing to ditch the GPZ 7000 for the GPX 6000, and JP is not. Why? JP pays bills with gold, and in his opinion the GPZ 7000 is what he has to use as a primary machine. Other machines like the 6000 are secondary for him. That seems equivalent to your situation. Me, I made the move from paying bills with gold, to being a casual detectorist. So I’m more in the boat with a different crowd than you. That’s the basis for my opinion, but it’s nothing more than that... my opinion. Some people I’ve just told them they should get a GPX 6000, no worries. You are a more serious operator, as are many here, and I’m not going to assume I know your business better than you do yourself. In my opinion, if everyone would just read all the Minelab info, including the star chart, and accept that it is all ballpark accurate, a lot of this fuss could be avoided. Some of the star chart positioning does involve intangibles, like will easier learning make for better operators. It simply is what they say it is, no big mystery, but like everything when you try to be simplistic, a little wiggle room is left on the table. From what I’ve seen, Minelab has nailed the positioning here very well, below GPZ 7000 but above the rest. But do not beat me up if somebody finds gold with a Gold Monster that a 6000 will not see, $900 versus $6000. That could happen, so does that make the Monster the better machine? Maybe, for some people, especially those with small gold and a ton of trash. In a trash pit, the Monster operator could wipe the street with the 6000 owner. The world is not black and white, and almost every machine has a tiny area that it really excels at, where others are weak. As far as Geosense, we know the GPX 6000 has far fewer settings than the GPX 5000, yet it claims better performance across the board. People say that can't be done with fewer controls. What if the machine was reading the ground and adjusting the timings for you, instead of requiring you to somehow know what the ground and gold is like before you've even started? I'll never claim I really know how Geosense works, but it should be obvious that it is this feature that allows for so many settings to be removed. Part of our thinking on how to choose a proper 5000 timing has been built into the 6000, so we do not have to make that choice. With the 5000 odds are casual operators are not tuned for optimum performance. This is hard to do with the 6000... you'd actually have to purposefully misadjust it.

Normally I use USPS but they had stopped all deliveries to some countries during that time.... the endcaps would have cost about 35 dollars...to the land downunder. I remember one time I shipped GG head phones over night to Shizuoka Prefecture Japan .....someone in great need ..it was FEDX 285.oo. And it ended up being 2 day shipping time. He did getting several Plat...and killer golds. Him to me.. Still keeping up with you on the ring count, just. Good to have some friendly competition brother.

One thing ML is really good at is to diversify their machines to fit various needs. IMO all current models have individual applications that are not matched by any other ML model. There never will be one-fits-all detector, ever. But what the 6000 appears to do is to sum up all that has been learned from the 5000, GM and SDC to feature an intelligent automated machine in a light weight format. To me, a good day prospecting is not just measured by how many grams I have recovered (if any...), but rather whether I had fun and a good overall experience. The 6000 appears to be perfect for that. But of course, I am in the fortunate position to have multiple options to choose from, based on the circumstances and how I feel that day. It appears though the 6000 is thus far the most overreaching detector WRT to applications, also indicated by the fact that it is the only high-end ML detector that comes with coil options (aside the 19 inch for the Z). This tells you that it is supposed to be an all rounder, with emphasis on handling and smart automation. I am still really curious though if the Geosense technology will give you yet another niche not matched by any other ML detector. But to be honest, I would not really care if not.

Concealed same cameras do wonders. Nobody should ever assume they are not being seen these days.

The Federal Communications Commission (FCC) here in the USA has strict controls over these kinds of things. And some local laws even prohibit (or at least used to prohibit) scanning police frequencies (i.e. automatically searching multiple frequencies to pick up a police communication), so it's more than just transmitting that can be illegal. How are metal detectors legal? Because their RF range is limited due to their low power, for starters. (Metal detector manufacturers must go through certification with the FCC before they are allowed to sell a new model of detector. It's not just the low range that allows their use.) Building a device capable of jamming (at a distance) is unlikely to fit under the low range allowance. And that seems likely to be just the tip of the iceberg of laws that such a device would break.

Yes! This!! 100% I did pretty well with the GPZ 7000 with 19” coil. I also, despite harness and bungee, after days of use, felt my shoulder go “boink” and that was that. And now, no more of “that!” I've got zero issue admitting I'm not the tough young buck I used to be, and taking it easier with what I have left is key to keeping the game going for me. The youngsters do not quite get it, but plenty of you know what I'm talking about.

Those are calcium sulphate and silica veins, gold has only been found in trace amounts by Curiosity so far. Minelab tried to get NASA to put a GPX 6000 prototype on the Perseverance rover, but their marketing team couldn’t get spacesuits in time for their prospector models. 😉 https://www.nasa.gov/jpl/msl/nasas-curiosity-eyes-prominent-mineral-veins-on-mars/

How about a good old fashioned stakeout? Just remember to have eyes on the site!

It looks like some type of commercial resin mix! Like used in making bowling balls! 👍👍

Bluetooth sweep frequency jammer might knock out their headphones if they are wireless. Not sure what kind of range they have. Wouldn't be easier to put in some motion sensing lights and an alarm?

Looks like it is falsing off your car. If it was your cable it would also do it in the air.

As far as I know I can neither confirm nor deny that question. I will reveal now I was involved with Vanquish, but after Equinox I kind of decided it’s pointless for testers to get involved in direct release commentary. I put in huge effort, and took not a small amount of risk to get people early info on Equinox, but looking back I unfortunately remember the rocks that were tossed my way when I said Equinox was the real deal. Just another shill, after over twenty years of accurate reports. Funny those same people now agree it was a game changer, but I’m still the suspect one? How does one fight being accused of lying by omission? I'm guilty for what I've never said, but that someone imagines I should have said? Basically, it's either be a calabash style "basher" (it's in the name even ), or be accused of being a shill. It puts a guy off the entire exercise, as despite rumor to the contrary, Minelab does not require testers to ever say a thing. Just the opposite really. It seems best when I just stay in the background, and stick to posting photos, specs, manuals, and other general info. How about this? The GPX 6000 has no threshold adjustment (just on or off) for $6000.00. No coil smaller than 11" round, only three coils (one that can’t be had yet), no disc. That's makes it shite, no reason for anyone to buy one. Minelab says the GPZ is still top dog anyway, so the right combo of prior models is all you need. There you go. I can take a piss if that’s what people prefer. Maybe I have street cred now. You’ve said it’s a simple equation for you Jason, ergonomics do not matter to you, only pure power, plain and simple. I see no reason why a guy with a GPZ with full coil complement would be considering a machine that Minelab says is a step down from a GPZ. Other than that you are conjecturing that the machine is better than Minelab has let on, because we know they have a long history of understating things? Or something to that effect, that maybe there is some niche where the machine will best a GPZ? That’s honestly something I can say about the Gold Monster versus GPZ, so why would the 6000 be any different? Salt mode exists on the GPX 5000, and why would that not work on the salt areas where that is an issue? There are even salt coils made for the 5000. SDC has a salt mode - who uses it? Have these possibilities been exhausted? It’s not like the capability does not already exist. The GPX 6000 is packaging its own performance mix, but none of it cannot be achieved by at least one other machine set up right. It does get dicey trying to compare small gold performance. Nobody is saying the SDC 2300 is bad at small gold, but the chart below gives only one star. Well, think about it, SDC 8" mono versus 6000 new type 11" coil. Might the 6000 be getting similar size gold, but just a little deeper across the board due to the coil? These are the things that go into the charts, not a basic this inches versus that inches. It's a sales guide intended to help sales people ask some simple questions that direct people to a better choice. The trickery and games people assume are counterproductive to getting people into the proper machine for what they are actually doing. That creates happy customers, not tricking them into buying things they do not need. Minelab has made zero claims of new absolute performance benchmarks, though again, it gets fuzzy in small gold land, where we are dealing in millimeters, not inches of depth. Minelab are just saying there is more gold finding capability packed into a couple groups of settings with the 6000 than exists on a 5000 in any one setting, that might better suit a lot of people than some of the other options. Number one clue about the chart below... only Minelab coils figure into the equation, and aftermarket coils can change the equation. I could make a sales pitch to you on the GPX 6000, but every discussion with you comes back to efficiency. Do you need a 6000 for salt areas, really, even if it kills salt signal completely? What effect does killing salt signal completely have on depth - are you really ahead, or better off at a crawl with no salt setting? Are you going to find enough extra to make that worth the extra machine and it’s cost - and the time spent finding out maybe those salt areas are not hiding as much as thought? That’s really not a machine question, but a strategy calculus. In general, saying all you’ve said, with a GPZ and full coil complement....... even Minelab is not saying you need the 6000. You seem well covered for your situation. Me, I am at the point where efficiency matters less than just having a damn good time. I like puttering with new things, even if I’m not finding much. That means I use what I like, and I’m not worrying one way or another over an inch. I do well enough to make me happy, and that’s all that matters. So a different perspective and reasons for needing a detector from yours. The GPX 6000 could have been custom made for me, and actually was in a tiny way. That being the case, it should surprise nobody, that just like Equinox, I’m GPX 6000 fan number 1. But maybe that enthusiasm makes me a poor candidate for the type of reporting most people seem to crave. Me, I’m more the giddy kid with a new toy, and don’t need anyone bringing me down. Life is good. The general consensus, which I can’t disagree with, is people wait about six months after release, to collect reviews from regular purchasing consumers.

I know that this is used to protect those historic areas here. Very effective. And when it comes to archeological research they remove the cover layer with the scrap metal and do their job, as the first layer of soil has to be removed anyway. Effective, cheap, and very annoying for the tomb raider.

Oh, regarding cameras. They are just no deterrent. People cover their faces, police are often slow to respond to such crimes and archaeologists don’t usually have the funds to finance private security. Saying that, three people were recently identified from footage taken with wildcams during the day after their mugshots were plastered all over Facebook.

I use cellular deer cameras for security. If someone tried to steal or damage them it would be too late, the photo would already be sent to me. They are easy to hide. They are relatively inexpensive and some last a long time (up to a year) on lithium AA batteries. Non-cellular cameras are less expensive. All can be bought with a steel box that makes them tougher to get to or damage.

Hi EL, It was my first run with the DEUS and it was pretty warm out in the sun. I managed to find a complete and in very good shape pick, a small two piece button and a few musket balls and lead pieces. One thing I keep finding are wads of thin lead sheets. I would guess that was what they bought to melt for pistol/rifle balls? I need some time with the DEUS to get it down and I bought it with the 11 inch coil when the 9 inch was probably what I needed.

It kinda looks like western Australia without bushes and trees... strick

Hey Jason there are drone hacks that can remove that height limitation. I only have the Mavic pro that’s fully hackable. I’m not sure about full hack-ability on the 2.

?? That is some kind of easy. If it was my property I'd pepper it with scrap metal. May be there is a milling company close to you. Asking them for scrap metals made of brass, copper, iron, aluminum, etc...and what they want for, and then sow this. Will be fun to watch them...lOl 👀😜😂🤣 oops...forgot this...: Welcome aboard, WhiteRabbit.😊

Would love to see that piece after an acid bath.

There are these style that don't include the glasses, but still let your hear the environment too. Unfortunately not AptX either though... I stopped using headphones entirely because of rattlers and I like to listen for my dog in case he hurts himself. I dig the concept of having phones that let you hear the environment. I can see XP making something like this for some reason.

They will work, just not low latency - bummer.

I've done well with the 8x9 concentric especially in parks with bottle caps and trash but finding any concentric for a Tesoro is really tough. The 3rd party companies seem to only make dd's. I currently swing the 10x12 widescan. Mars Tiger is probably the closest you will get to that. Nel has a sharp shooter that might be good but with all dd's, flat iron can give you fits in some cases and bit trickier to tell apart with a single tone machine but not impossible. About the noise, does your machine chatter if you tap the side or wiggle the coil cable? See if your getting noise near the coil end or maybe it's the connection at the control box. One easy way to check for emi is by dropping the sensitivity down and see if that makes a difference. The Tejon has all metal mode that I can clearly hear any fluttering from emi and the larger coil is more sensitive to that. At one point I had an odd flutter and thought it was emi but turned out to be the ground balance pot that I seemed to have fixed with some cleaner made for pots. The Mojave has an auto gb so doubt it would be that.

As a guy with glasses and hearing aids... I like! I may order a prescription set as polarized sunglasses, could be great for wading work as well as the desert.

Forget the GPZ, you may need to use some discrimination for gold due to all the meteorites, and it will be getting harder to detect as it’s mostly non-ferrous metals like aluminum and titanium that we have also been trashing Mars with so far:

Me. With electronics, I reject the premise, which is that multiple functions cannot be implemented as well in a single device, as in many. I’ve gone from needing at least six detectors to now needing three. The Equinox had a lot to do with that. The 6000 for me takes it down one more machine, as with the 6000 I no longer feel I need a hot VLF like the Gold Monster, 24K, or Gold Bug 2. So I sold the 24K. If I need disc while nugget hunting, the Equinox covers it. The 6000 will also probably serve as my Tahoe beach detector, which previously I’d been trying the Impulse AQ. After looking at the situation, I started selling off excess machines again a few months ago. Not counting machines I’m playing with, I’ll be relying on three detectors going forward. GPX 6000 (nuggets and beach), Equinox 800 (everything), and DFX (to run Bigfoot coil).

The importance of using a good quality metal detector suitable for prospecting has been widely explored in great detail. The introduction of the GPX 6000 highlights the gains in technology and thank goodness, ergonomics. Weight and Balance, at last. Matched by performance and cutting edge technology.. The one fact remains that at the end of the day the key is to get the coil over the gold. Some truly magnificent gold that has been found, could have been detected by any half decent prospecting machine. Still we should invest in quality and the new Minelab sounds superb. We need to utilize every tool at our disposal. Often after extensive research, Google Earth images, maps, books and word of mouth can all lead us to a certain goldfields. When we arrive there is a lot of suitable ground to explore. Perhaps too much ground and not enough time to give it the attention it deserves.. In an effort to narrow the search I have started to use a drone when exploring a new area. It allows me to gain perspective, to more clearly focus on areas and features of interest. When the terrain allows it, this will same me a lot of time and increase my odds of putting a coil over a target. Viewed from the ground vegetation can mask features which kind of pop up when viewed from the air, the drone allows me to focus on a smaller area of interest.

Has anyone tried them with a metal detector? I came across an article which displayed some Bose audio sunglasses. The concept was not something I had really considered but when you read about them they are built for athletes that need to be aware of their surroundings to avoid accidents. We detect in areas where we need to avoid accidents and critters also so hearing outside of headphones is beneficial. This would also have the potential of eliminating hot and or uncomfortable headphones for me in the desert. I don't think they could work well at the beach with crashing waves. Maybe we can begin a review of these Bose and other audio sunglasses here. Of course there would need to be some with LL and other technical specifications to work with our equipment but it could also be a new product idea for one of these companies. https://www.bose.com/en_us/products/frames/bose-frames-tempo.html#D61A74D4CFE947DB6685D4D8CE1982FC

Joined this forum and wanted to say hi. Started detecting in January when I purchased an Equinox. Have only been detecting on the beach areas around Fort Myers so far and love it.

For sure police are too slow to respond, my county has a 45 minute response time because we have so few of them. We have a few options here, so it is still safe. However, my cameras have not only identified suspected home invaders, but they also cause early "turnarounds" in my half mile driveway. I see the turn marks almost weekly. Takes em a few seconds to realize they should have smiled. 😀 There are flash options to let there be no mistake. Sorry to see so much disrespect for the law and decorum in general where you are.

👍👍 ty for that answer. I hadnt really paid em much mind other than the necking,as i was studying where entrance ways etc may be and or what mayve came 1st. Naval rifle range or p.o.w,s? Together? Yes it is a p.o.w site,im havin limited success findin location specific info on this particular 1,thisun didnt house the officials but id think thered still b few coins or relics to b had and lots an lots of practice on purrrrfect plugs,after we dry up lil bit. Ive done more walkin lookn last few days as try to go with the flow of mother nature. Im not native to this location,they once boasted of the worlds largest pickling company here,along with turpentine an timber,matter of fact i found what appears to used to b purty good size turpentine distillery yest by looks of refuse an concrete pads. There was literally a small hill of ol collecter pans an scrap iron. I tried lil detectin where it was drier to no avail,except fer broken whiskey jug an ol rootbeer bottle and a lil copperhead,it wasnt rainin so it was all in all just a most enjoyable day,and ima do same thing 2day. Only diff is,i have no planned destination this morn,except to see whats over yonder. Thought bout beach but,ill wait lil bit an see if the better half mite b interested in a few days at beach,may even bring the pup. Kinda waitn on creek waters to recede an warm lil,bcuz thats what i think i like most bestest. I spent all my life at sea,or biggest part,nowadays im partial to freshwater an shade😁 cupla col beers. No worries mate. Gday😉

Having worked around heavy machinery and loud tools most of my life (farmer), I am used to having earplugs in, so not a problem for me. My hearing is still very good by their test but have lost some high frequency which is normal as we age unfortunately. I hate earphones in our temps and the loss of normal ambient sounds can be dangerous. Have used external speakers exclusively but they are a pain in windy conditions as volume has to be turned up and didn't realize how fatiguing the extra noise is until I used these. Please Note, I am not recommending these to anybody, just that they suit me very well.

Your a lucky man! You don't even need a detector to find treasures in your front yard!💩👍👍

I have a Mavic 2 Zoom that I use in the Rockies and Arizona. It's been a real time saver scouting prospect, mines, and outcrop up in the mountains. I can see which have features that interest me, it's high enough resolution to tell the difference between ore piles and waste piles. Resolution is good enough that I can pretty easily identify outcrops. The zoom is actually surprisingly good too. The height limitation sucks around the high mountains, but I find a high spot to launch and combined with the zoom I've been able to see whatever I've sought. It hasn't been as useful to me in the desert flats. But I did use it to track thieves down, and you can see 2-tracks left by trespassers offroading around fences and see where they came from, or easily monitor thug compounds from the air, stuff like that. I've flown it almost 5 miles each way, so it's possible to cover quite a lot of land and distance as long as you have a line of sight between the control and drone (another reason I find a high spot to launch).

When I had a Tejon I only like the concentric coils for it. I didn't care for the dd coils on it but if you have mineralized ground you need to use dd coils.

I actually have some hogweed in back of my house, only reason I know is because I didn't know what it was. Never got any on me. I do have a good amount of poison ivy front of my yard, I left that for one of the neighbors that had a little fluffy dog that liked to sniff around it and leave treasures there. Ivy now keeps the owner and the dog away so there is a benifit to it 🙂

Thanks. On this beach the regulars hunt for gold as well. Gold is rare for me to get here on dry land. So I concentrate for silver and sometimes something gold shows up 🙂 Don't waste your time on digging like me, keep hunting for gold under water!!! All the best to you on your next hunt!

I have a Buddy that bought them for fishing videos! Problem with Prospecting is when looking around your giving away your area. Other than that they work fine and we’ve made some great videos with them.

A friend of mine who is a bat biologist uses a drone to look for open adits to find potential bat habitat, and I just recently used mine to see the extent of an old drywashed area. They provide very good high resolution images of hard to access areas, and definitely can be a benefit when surveying a large area more quickly, but they won’t replace boots on the ground.

We've all seen them. There are these pages that make you click and show you treasure and say greatest ... This link is to a site that shows mostly the best finds from the UK. I learned a new way to rank the finds by viewing these. https://www.msn.com/en-us/news/world/metal-detectors-led-to-these-stunning-treasures/ss-BB1esUcZ?li=BBnbklE

lets all hope for a good season with good gold prices and lower fuel prices

We have from 1 foot to 4 feet of muck then we hit gravel top of gravel to bed rock is about 8 feet some times more hardly any big rock in the gravel . The big rock has been pushed up to the top due to the frost with the freeze thaw most of our gravel is thawed if we strip off the muck in the fall the blue berry bushes will have solid ice under them I don't even know how they can grow we always hit flowing water when we get close to bed rock

As I stated recently in a different thread, I want to recommend something to ease the swinging burden of nose heavy big coils. Start with a unit like docs detector buddy, or get a 2” wide strap make a foot long loop at one end which arm goes through. The other end goes around shoulders and stops about a foot above detector arm cuff. Now add an 8” or so length of elastic or thin bungee to the strap end. Put attach a hook at end of elastic with zip tie. Add a U-hook to center of arm cuff strap with zip ties. Now just Adjust the strap length until when hooked up the coil is suspended by the elastic 2” above the floor. Now the detector and coil will seem weightless. Attaching at the cuff strap provides perfect up-lift in line with axis of your arm, unlike when the strap attaches to the shaft or handle, which demands wrist correction and effort. By using a hook the detector can be detached easily for target digging.

2/ The Anfibio’s Strengths: Audio Every Nokta / Makro detector I try seems to have better, cleaner, more informative audio than the last. The Anfibio is also what would be termed a “high bias” detector in that when you learn to listen for extension in the response--you can become very accurate. This sharp, clean audio lets you hear a real lot of detail about what is under the coil. There are several U.K. “YouTube” videos out of hunters placing nails right on top of coins and still being able to detect the coin with the Anfibio. This is a great demo of just what this machine’s fast processing speed and high-bias performance can do for your find count at old sites. I credit the operating characteristics of Nokta /Makro detectors with teaching me how to effectively use coil control target testing. This has found me a lot of deep gold and silver. With the speed and “clean” metal bias of a machine like the Anfibio this testing is much more effective--that is, when you use the coil to check a signal by going to the “cross-sweep”--iron and other corroded targets don’t “stay in.” Misshapen objects like scrap lead or “can slaw” are also more likely to give a broken tone. Again, good, non-ferrous responses have “extension.” What I learned was that there’s a whole other level of skill building, accuracy and effectiveness available to you with this clean audio and super-fast signal processing. Other strengths of this detector include a great display that lets you make fast adjustments for more exact tuning or “ID-ing” This also lets you jump from mode to mode instantly to cross check responses. You can move between different frequencies (5, 14 and 20 kHz), audio modes, and recovery speeds in an instant. There’s also a versatile Discriminate package that lets you manage your target selection with accuracy. This also a very deep and powerful detector with great small object sensitivity. The reason for this is because the Anfibio features high Gain circuitry. Gain acts to sample a tiny part of the returning signal and amplify it. This small sample is easier to manage in software and more of the distortion can be removed. So you have a cleaner, deeper signal. This means that small targets are amplified (or boosted) as they are received. Like many detector features--this is a “two-edged sword.” While small and deep responses are brought up to where there can be heard, other non-so good signals that are just across the “line” into the iron range are also amplified and may be “pulled up” to mimic good signals. For the beginner, this can be confusing as iron targets and even a few foils and crown caps are “hopped up” and may indicate as coins. However, the good news is that once you learn a few simple basic “fixes,” the downside of this tradeoff about disappears and this extra deep object punch becomes your best weapon. This takes practice, bench testing and time in the field. You could call the Anfibio a “Gain heavy” detector in that even at the presets-there will be good sounding false signals--from spikes, deep iron and some bottlecaps. As will be detailed further on--a good beginner strategy is just to “turn it down” and do some familiarization in 2 Tone audio mode. Even running at a Gain setting of “55” or “60” is a not a bad idea. This simplified less “amped up” audio will respond to these falses in more recognizable ways. An intermediate stage is to have one search mode with preset or higher Gain and a second weaker setting--to see how signals respond with less Gain. Going between the two is a great way to really get a feel for how Gain goes deeper--but at the same time brings with it considerable distortion. Targets sound fuller and better at high Gain settings. Where you see a response disappearing completely --or becoming broken in the low “checker” mode--suspect iron. Where a target just becomes weaker--this has a better chance of being a good, non-ferrous target. Gain also acts to “fill out” small responses--making them sound bigger, fuller and better. This makes for what I’ve heard termed a “steep learning curve” for the novice as there is the urge to go after a lot of sounds that are too small to be good targets. What helps is to gather more information than just “meter and tone” using the coil and the Pinpoint control. This lets you place your signals in context--to focus on the size, shape and location in the strata of each signal. When you learn to do this--each signal feature acts to confirm the others--giving your accuracy and conclusiveness a huge boost. For example there is nothing better than hearing a high silver tone, seeing a “92” on the meter and then getting the confirming narrow Pinpoint response that indicates a non-ferrous object. I call this the “In Keeping” method. (More on this later). Another effect of high Gain circuitry is that the detector is more likely to sound off on unusual variations in the ground. These can be patches of black sand or anything that represents a big change. So the ends of spikes, twisted wire or aluminum shards can all “sound off” on your first coil pass. This is where Another great thing about the Anfibio is its stability. Where there is not much interference from electrical sources it’s possible to run this detector at almost coil control comes in in that these are not consistent targets and will change or disappear on the cross-sweep or with varied coil passes. Where there is not much interference from electrical sources it’s possible to run this detector at almost full Gain.full Gain. However this type of setting has a downside too in terms of the false signals that it brings up. This is where learning some of the basic skills covered in this book can be of help--letting you mediate this high power with accurate signal type recognition and checking methods. Even where you do have a lot of interference--it’s possible to run a “balanced” signal so as to be able to hear good targets though the noise.
