  1. Patience in life is a virtue! But, even I was running low. Nice Spring days run into hot Summer day’s fast to be sitting around tinkering. Truck was all maintenance up before the lock down, RZR with new oil and filters, it was eager to roll. My detectors had a little dust on them, but batteries charged. I touched base with the Crew and 6 of us loaded up and stormed the desert of Northern Nevada. Heading to our camp spot, I noticed the desert was full of other Freedom Seekers mending their Soul for the need of the outdoors, a normal calling shared by all on this Forum. We set up camp and hit the nearest patch to Camp, with the skunk off our backs and with the setting Sun and cold breeze we headed back for some conversation, food and libations! 🥃. We strategized the following morning Gold Mission over the flickering flames 🔥 of our campfire. We decided to leave Gold to find more gold, not always the smartest move but, it was the first full day of the hunt. We hit the dirt roads to a spot I had in mind, leaving a dust trail seen for miles. Even the Antelope and Wild Horses wondered what the rush was about in the mornings cold temperatures. We finally arrived to a spot, I eyeballed years ago. We geared up and spread out amongst the hip high sage brush. 15 minutes or so, someone breaks on our Walkie Talkies, I got one as I seen a waving coil in the distance! The hunt was on, as our seasoned crew swung our coils to the first location of color. Another, call on the radio was from someone behind me and below in the dry wash scored a nugget! Well long story short, we all had a great time and I found the perfect rock to name the new patch “The X Patch”. The Crew slowly departed back to their Critical Jobs and the Weather changed on me, rain and wind I tossed the towel in. I did manage to flatten the curve of the lock down with 5 pounds lighter on the scale. Always, good to be back home, yet can’t wait to get out for the next hunt! LuckyLundy

  2. Was brutally windy today so figured I would hit a patch of woods where I have found other old coins but this time wanted to test out and see how the 3 tone mode in 19khz can handle probably one of the worst trashy spots in the area. There is a fire pit that goes back to the boyscouts and over the years people have burned their trash and littered the place so it has a healthy mix of aluminum, aluminum slag, old iron nails etc. Kept the MK at 85 gain, iSat 5, Disc at 4 (for the rust), and used n2 on Fe Vol. With some med/quick swings I would hit on a target then go over it and let the machine lock in. Still amazes me the separation and recovery speed on this machine in this mode. Targets aren't deep but it is certainly a good way to pick through the top layers of trash and reveal stuff in between. The V nickel was in a root tangle on a path about 6-7" down and small silver chain piece in with some aluminum can slaw. V Nickel is 1884 I believe but in rough shape but nice to know there is stuff still in the area.

  3. Had an unusual, and great day. First thing that happened was I found a silver ring...my first! 30 minutes later Dave dug his first Barber dime, an 1893 S in great condition. 30 minutes later I got a nice, clean signal, and was amazed to unearth a 14k gold ring! How weird is that on that old trail. And the stretch we were working has almost no traffic now, other than the occasional hunter. So hunting along about 15 minutes later, and the DFX gives a solid nickel reading, and out pops the 1903 V nickel. All of this in about 250 yards of road, of the .77 miles we covered today. My best day, EVER! Jim

  4. First of all, "power" is a wrong metric for metal detectors. A single-frequency VLF with a perfect TX coil will transmit zero power since all the current gets recycled. A traditional PI has a total loss transmitter but even then "power" doesn't make much sense. For the "transmit strength," yes, it is current that matters along with the number of turns of the TX coil. We call that the "ampere-turns" (N*I) and the TX magnetic field is proportional to N*I for a given coil size. It doesn't matter what the driving voltage is except that it is part of the system design. As Pimento suggests, you can't look at the battery current and tell anything. TX pulse width and pulse frequency also combine with peak TX current to determine average battery draw. And once you know the peak current, that doesn't necessarily reflect actual performance. For small nugget detection you need to be able to sample early and the higher the peak current the harder it is to do that. Early sampling isn't important for an Atocha bar detector so you can dump 100 amps of current through the coil, but that same system might not be able to detect any nuggets smaller than, say, an ounce. At all. Finally, there are methods of energy recycling in PI detectors, although not yet prevalent in production models. Another reason why you can't look at battery consumption and determine anything.

  5. Well, perseverance, study, asking questions, and dogged desire, are slowly paying off! I was going to go to an old park this morning, but the weather was crap, so I didn’t make it. Things settled down in the early afternoon, so I went and hit the parking strip here and the next door neighbor’s house. I wanted to apply some of the things I’ve learned from some questions I asked here on the forums, and from reading Andy and Clive’s books. It was a good afternoon! I found my second Merc - a 1943D, my first nickel - a 1963 Jefferson, AND my first Buffalo nickel - 1928. I’m feeling much more confident, and starting to correlate what I’m seeing and hearing from the Equinox to what’s coming out of the ground. Looking forward to getting out to that park!

  7. Slipped out yesterday for a few hours. This spot is close to home. A short drive and a walk just a little over a mile to it, most of the walking is in the water so I got my workout, with treasure. Love this ring, a big surprise when It came up. Nine grams of 14k with a big beautiful red stone. Another surprise was the silver walker, no date. A silver rosey ........... then the two war nickels. Good luck to all and Be Safe! Gold Ring #39 FTY

  9. These newest two updates add a lot to the Simplex's already great performance. The new Park 1 one mode was awesome--very clean audio that gave a nice centered high tone on coins. Kind of reminded me of the Anfibio in how it brought up the round, solid objects really well. Actually had to turn down the Gain but the machine was still getting nice depth. I was working with a pinpointer and used the Mute feature several times to prevent any sounding off. My favorite set of phones were actually too loud on the higher Volume settings settled on "H2". By checking my targets on the cross sweep and in pinpoint for size I was able to dig mostly coins including this '35 King George the 5th cent. This is an amazing detector--and not just "for the price." It has a lot of punch, great audio and the features to make for pro-level versatility. Can't wait to see how this machine does in the salt water. Great job, Notka Makro!

  10. Yesterday evening was a beautiful day to hunt. Didn't get to hunt long. The school was mowing the lawn, or rather the acreage. Might not look like much but the war nickel is the 3rd in 4 months. Not bad for a presumably hunted out site. Oh, by the way a site is never hunted out. There's always something left, waiting for the next generation of detectors or the detectorist that my be an unconventional hunter. I might explain that statement at a later date.

  12. Jeff, I suggest picking one mode to start with, the is exception gen mode. I have some pretty goofy soil here in PA and It's full of iron inside the clay. I like 3 tone and don't loose any depth with the disc up to 20. Learn on one mode and then transfer the knowledge to the others after time. One trick that will help you focus in on good targets is flip flopping your tones run your fe tone at 15, your gold/non fe tone at 70 and your non fe tone at 35. This will give you a distinct break in the sounds that will give you another level of discrimination (by ear). Test it in a garden with silver and copper and you will hear a low tone on those targets (it will not sound like iron). Gold and aluminum will have the same high tone. When I hunt in bad soil that is combined with EMI, I lower the volume and work through the chaos. You will find that the MK will give you a very strong sound on a good target even though the machine is going crazy. At this point do not watch the ID's let your ears tell you what it is. Thats where the tone flip comes in. Also when it rains like crazy here I run beach mode to take care of the wet mineralized ground and it works quite well. Running 85 gain will take some of your problems away and once you get a faint target, bump up to 95 and play with the target to get a better idea on what it is. Here's a good starting set up 3 tone, Gain - 85 Disc - 08 Notch - 01 Fe. vol. - N2 Tone break 04 - 70 Tone - 15 - 70 - 35 isat - 02 When you change settings do it one at a time to see what it does to your machine in your soil and record all the info. Once you master one mode you will have mastered them all, other modes just require small setting changes. And there is nothing wrong with 14khz

  13. I read it and it is awesome (but then again as an electrical engineer by training, I guess you CAN call me a propellor head). Explodes a lot of myths and shows that the number of variables in detector design combined with the number of variables in the detecting environment means there are very few absolutes in detecting. In other words, it is a heck of a lot more than about the amps, the volts, or the watts.

  14. Responding to Peter in SA. Back in the mid 1980s I had been involved in the introduction of the Minelab GS15000 metal detector at Wedderburn in central Victoria. The early Minelab crew were a bunch of clever people from Adelaide university who got together to produce an Australian made metal detector which could challenge the big American companies. Wedderburn was chosen for testing and development due to its reputation of having very mineralized, difficult soil conditions. A number of Australian built detectors had failed to live up to expectations, defeated mainly by the hot soil conditions in Western Australia and central Victoria. The GS15000 proved to be a better machine for these conditions than its competitors and soon gained acceptance throughout the gold detecting fraternity. Craig Hughes, who was part of that early team came up with the idea of a coil towed behind an ATV. An area near the famous 'potato patch' just out of Weddurburn was chosen for testing, using a Honda three wheel ATV (horrible unstable beast of a machine). The coil was fairly small, but I can't recall the exact size. A GS15000 provided the electronics, and although noisy, did work with a small bit of gold recovered. (a few grams) Even though the manual ground balance made for uncomfortable detecting, the concept had been proven, much to our surprise. In 1987 I was involved with the testing of the GT16000, which was the first ever automatic ground tracking. This machine was a major breakthrough and really put Minelab on the map as a serious contender for the title of the world's best gold detector. It dawned on me that the feasibility of tow detecting was a reality now that a detector could stay balanced automatically, and I contacted Don McCoy, one of the original Minelab team and asked him to build me a coil suitable for towing. The result was a rectangular coil about 3' x 2' which was very stable and sensitive. I purchased a Yamaha 4 wheel ATV as a tow vehicle and with the addition of a suppressor managed to keep the EMI to a minimum. The first day of testing yielded a 6oz lump, which was a big surprise, and paid for the ATV in one hit. I sent Don some nice specimens as payment for the coil. I later sold that coil through Miners Den in Melbourne when the SD2200 was introduced. The SD2200 was of course the first auto ground tracking pulse induction detector, and naturally I soon made plans to adapt this concept to 'sledding'. John Hider-Smith, Ian Jaques and myself had been involved in prototype testing of Minelabs first pulse induction detector, and Bruce Candy had taught john how to wind mono coils. One of Johns coils was used in the first PI tow coil testing where we discovered that a 4 stroke engine was not feasible due to the high susceptibility of PI to EMI. With experimentation we discovered that diesel was the way to go as no spark was required for the engine to run, and an isolation switch for the alternator solved any EMI problems. We later used a GPX4000 which worked even better. I have to close now due to having to shut down internet but will add further details later.

  15. Just out of work at the moment because of all this Corona Virus stuff. I bought a detector to get me out of the house and I figured outdoors, good exorcise, and sun. Just me and my detector and hopefully some silver and a few gold nuggets. Away from all the Corona crowds.

  16. Spent another day out in isolation in Gold Basin, it was warm at sunup but thankfully never got unbearably hot. I picked up a few more meteorites including one so tiny I didn’t realize what it was until getting home and seeing it under high magnification there I could see a tiny and tinier nickel sphere fused together with a small bit of the brown matrix circling the seam where they joined. At the end of the day frustrated with no gold to show I went exploring for someplace new to hunt and just a few minutes before sunset hit a nice signal in a wash under the edge of a small bush and roughly 12” down out popped a bright yellow chunk weighing 2.7 grams to chase the skunk away.

  17. From what I’ve seen with Equinox a dedicated Multi-IQ prospecting machine will be something. I’d kind of like to putter with a Tarsacci for nugget detecting but would again rather see a machine made for that use rather than force a beach detector to do something it was not designed for. Single frequency for nugget detecting however has not changed substantially in decades. This is the genuine truth whether people like it or not. When it comes to depth on larger gold nuggets and target id no single frequency detector made since does any better than my 13.77 kHz Compass Gold Scanner Pro did in 1990. And for smaller gold nothing has changed much in single frequency since my 50 kHz Goldmaster II in 1992. The machines have gotten more stable and lighter, with things like wireless and waterproof. But single frequency depth and sensitivity plus discrimination accuracy are basically the same as 30 years ago. All this marketing about more depth and more sensitivity is mostly an illusion, with the same old tech endlessly repackaged. My iPhone is an amazing thing, but does it really make a phone call better than a 30 year old dial up land line? Actually, maybe not as good. That is why most of my VLF reviews the last twenty years have eschewed competitive depth tests and focused on features. Because in most cases that’s all you are buying, and thinking some new single frequency VLF is really going to change anything... I’m way past believing that. These machines actually were game changers..... Bud Herschbach with original 19 kHz Fisher Gold Bug and 3-3/4" coil In 1990 The Gold Bug was 19 kHz, “S” rod, super light, hip or chest mount, elliptical coils... revolutionary physical design for the day, but no discrimination. Steve Herschbach with 13.77 kHz Compass Gold Scanner Pro in 1990 The Gold Scanner Pro had great depth on larger gold in particular, and was mixed mode - full metal audio with separate full range visual discrimination meter at same time. A nugget machine way ahead of its time but unfortunately touchy and unstable, very knock sensitive. Makes a Gold Monster look rock solid for coil knock sensitivity by comparison! Steve with White's Goldmaster II in 1992 The Goldmaster II at 50 kHz was the first true high frequency nugget hunter, and blasted previously low producing locations wide open with its small gold capability. The Gold Bug 2 at 71 kHz in 1995 bested it on tiny gold but at some sacrifice on larger gold at depth. Recent designs have again validated the 45 to 50 kHz range as offering the best balance overall for depth on larger gold while retaining small gold sensitivity. Anyone who actually puts one of these machines up against the best made today would be shocked at how far we have not come with VLF in the last 30 years. The real advances were made in PI and frankly when it comes to the most serious prospectors Minelab has owned that market ever since the SD 2000 in 1995. Even there, put a good 18” coil on a SD 2000, people would also be surprised at how little has been done since to advance depth on multi ounce and larger nuggets. PI capability on small gold advanced by leaps and bounds, but the lunker nugget capability not much at all. That’s why we read all those tales from twenty years ago and why new huge nugget finds are so rare.

  18. Running any detector (except maybe an F19/G2+ in disc mode) at full gain where I detect is next to impossible due to the mineralization. I can run most detectors including the Kruzer between 70% and 90% of max. It is just kind of weird that the 3 Tone mode on the Kruzer simply will not work here unless it is at 90 gain. It will not hit a 4" target with any kind of decent audio or numerical target ID. Below 90 it is a jumpy, crackly, static filled mess. It makes 4 Tone sound lovely by comparison. At 90 the tones are crystal clear and the numbers are fairly stable. At 90 however, it will also make an 1/8th inch piece of 3" deep aluminum sound fantastic. That is a big problem in my opinion since I bought this detector especially for coin and jewelry. I can run the discrimination at 5 or 6 in any mode on the Kruzer and it is quiet enough to detect even with the gain at 90 in 3 tone. I had similar problems with the T2, F75 and Omega but in the opposite direction. I couldn't run them over 60% without them going absolutely nuts so they got very little depth and awful target IDs. Steve is right as usual. There are many places in the Western USA where single frequency detectors are just unreliable. I was in the Colorado mountains today at a well known gold producing site trying to run my GM24K. Luckily I took both coils since the 6.5 inch concentric was overloading with gain at 3 and VSAT at max. The 10x5 DD worked okay at gain of 5 with VSAT at max. Of course there is pea sized to marble sized magnetite all over the ground. I should have had my Nox 800 and TDI SL. I will take the right detectors next time. The picture below is some of the small stuff. I just hover my pick magnet an inch above the ground and this is the result. Jeff

  19. I'd say we can!...LOL Fortunately for me, the alkaline soil here may turn them red, but it doesn't chew them up. The first coin I ever found was an 1889 V, and I found one other just inside the CA border from Nevada. it was laying on gravel and not in contact with the soil, so is nearly perfect. It's a1900. Jim

  22. Welcome to the forums. I see you snagged an AT Max. I am a long time AT Pro user and Good friend runs a Max. Good machine but if it tends to eat up batteries you can snag a set of rechargeable AA lithiums like BlackUbe which I use on my Tesoro or the RnB battery pack made for the AT series. I have the RnB on my AT Pro and get a good 40 hours on them. Performance wise the BlackUbes will do the same but I think the RnB will give you proper read out on battery level. BlackUbes will run flat out then run out so the battery indicator might not be accurate. RnB are pricier but either option will keep you going strong for much longer.

My wife refuses to check my pants pockets so they went through the wash. The sharp edges of the nuggets were rounded off, i guess it was from tumbling around in the (front load) washing machine.

  30. Thanks everyone for contributing to this topic which I guess more appropriately could be titled "High Mineralization And Single Frequency VLFS. Steve, I am starting to miss my Tesoro Lobo Super Traq. It was simple, basic all metal operation and it could handle mineralization pretty well at 19 kHz, I just dug everything and really had no expectations. The Gold Bug Pro, F19 and Teknetics G2+ are in that same boat too. Simple to use, very effective all metal modes and fun to swing. So, I did a re-hunt of the area that I have been testing with the Makro Kruzer 14 kHz and Makro Racer 2 (they are both really nice detectors btw) which is a baseball/soccer field I have never hunted on until I got the NokMaks. I used my Nox 600 and casually hunted the same area. By casually I mean I was not overlapping sweeps or being particularly careful. I was just out walking my dog and swinging my 600. I should have just used my Vanquish 440, the Nox 600 was overkill!!!! Unfortunately, I found a lot of legitimate targets. I guess I will have to hunt this whole area again. On the left side are the targets that really bug me. Lots of low to mid conductors that should have been easily and correctly detected by the NokMaks and could have also been gold jewelry. None of the targets on the left were deeper than 4". As I said before, in 3 Tone which is the Kruzer's designated trashy park coin/jewelry mode, those targets will either not be detected in the default settings or their audio was so weak and blended (meaning I got low mid and high tones at exactly the same time, so one really mixed up tone) and their numbers were so jumpy in the 60s to 90s, that I probably considered them to be just past the edge of detection or junk targets. The targets on the right side of the plate are also troublesome. I can only assume that some of them were wrapping around into the iron range or again, their audio was so weak and filled with static that I just walked over them. With the Nox, all of these targets were no brainers. I knew almost exactly what I was digging. Even the pull tabs sound different from the nickels enough for me to know when I'm digging one or the other. The only target that fooled me was the junk ring which I expected to be a zinc penny. So, this is not about the shortcomings of any single frequency VLF detector that operates below 15 kHz. This is about bad soil conditions and what those conditions do to perfectly good detectors. It is also about how well simultaneous multi frequency detectors with plenty of recovery speed and target separation do in bad dirt. Like kac said in a previous post, Gen mode on the Kruzer and the Racer 2 would probably work really well in my dirt. Yes they do even though they still up average targets. However, I expected (since I just can't believe it without way too many hard life lessons) all of the great detectors that I have tried in the last few years to actually work in more modes than a threshold based all metal mode. I did not buy them for their all metal mode. I bought them for their discrimination capabilities..............

  34. Steve, I don't have nearly the experience or knowledge of guys like you and I keep making dumb mistakes by thinking a beautiful, recently designed VLF single frequency detector will actually work here. I give up. Even the 24K drove me nuts yesterday. I did manage to find a .3 gram nugget but I got lucky since it was in the hole with a fragment of tin. I reburied the nugget by itself at 2" and it read a 0 to 33 (solidly in the iron zone) on the 24K because of all of the magnetite. The same nugget air tested at 65 to 80 (solid non-ferrous numbers) all the way out to past 4". I gave up using Iron Cancel and just dug anything with a short zip after that...... I really want to support our metal detector manufacturers and like everybody else I love a new toy! Hopefully NokMak, XP and our US manufactures can come through with more versatile, modern multi frequency VLF detectors that can operate in our western USA dirt soon meaning before we all die out here.

  36. You are correct, a war nickel usually comes from the ground with a distinctive white color. The nickel was in bad shape when it first came out of the ground. To start with I was not sure what it was, green on one side, more like the very old copper coins I dig in my area. No idea why the corrosion, maybe some sort of fertilizer the county used in the past. This time I used the Equinox. One thing I can say for sure, the signal was awful, couldn't get a repeatable but the sound was just different. The ID was in the 11ish range but an in the ground nickel will usually read a 12 if I'm hunting in Park 1 presets. Since I've been hunting mostly with the TDI, it has me thinking about this area and why I'm finding stuff where I thought there was nothing, hunted out.

  39. I still need to try the tone flipping here. I do use 19khz more mainly because my pinpointer hates 14 lol. 14 is better on silver and better for relic. I find the 19 has a nice spread on mid range targets giving you more number spread between nickels and square tabs etc but you also nail bits of foil too hard. Overall there isn't that much of a drastic difference between the 2.

  42. I have not used an oval or rectangular pulse induction coil, only round ones, and this means that the horizontal placement of the coil is irrelevant and usually decided by the position of the lead. The shorter the lead the better the performance, so the point at which the lead enters the coil should be orientated as close to the tow vehicle as possible. With a large round coil shallow or surface targets will give a double 'beep' as the windings pass over, whereas a deep target will give a broader single signal (whuuump). Unlike swinging a coil, where a signal can be tested by multiple sweeps, sledding only gives you one opportunity to analyse that signal and decide whether or not to mark it. The occasional false signal from bumps or EMI spikes can be a nuisance, but good tight fittings will keep these to a minimum. In the vast areas of Western Australia a sled can be used as a prospecting tool, following reef lines, patches of quartz, or tertiary gravels, whereas in Victoria it is mainly a means of eliminating planned areas by systematic gridding. One definite advantage of tow detecting is that paddocks of crop stubble or long grass can be scanned which would be impossible with a hand held detector. The sled simply folds flat the flora without causing damage and it stands up again after passing over it.

  47. The concentric is exceptionally hot on tiny gold and still works fine in the worst ground, just not as good as a DD. When nugget detecting 1/4” or 1/2” is a big difference one way or the other. And most people who buy nugget detectors never really do that much detecting or know the difference anyway. As I have noted much of my ground is mild and the concentric would be my main coil. A lot of ground in the U.S. is not that bad. My haunts in Alaska were like New Zealand, very low mineral, and concentric the way to go. But there is magnetite serpentine ground in the Sierras as bad as anything in Australia. That’s when the DD comes in handy.

  48. Modified Minelab Excalibur's,............. Yes, on the direction of the winds and sea currents..then add in the tides, the matrix of the bottom, and direction the beach faces...So many more factors.......... And yes to the concentration of targets. specially out deep....Each beach has different concentration of targets based on there history.. Just a idea of one of the 10 spots I hunt...2017 I got over 40 gold rings from this spot. It still gives them up but much harder...Interesting this spot was dredged for gold in the 80's, but yet with all moving around it still has given many gold rings....I'm deleting/removing these files in a week also... I think the Fisher "AQ" will do well here... THEN 1950.......................................................AND NOW....2017.....
