GotAU?

Wow Rob, my first detector, a Micronta 3001, could have found that nugget. Probably just like the guy who found the Boot of Cortez lunker nugget in Mexico with a Radio Shack beeper. So why buy a GPZ?? 😃 Interesting backstory on your friend's nugget - what a beauty! It is inspirational seeing these and knowing they are still out there...somewhere.

That’s a nice coil. There’s others from more dealers for $137. Was it listed for less? I bought mine from Jim McCulloch with my 24k.

Any updated links for your project or plans? Can’t open your Google drive ones. Would like to see them! Thanks!! -Anthony

An embedded processor could analyze signals and filter out EMI that has a pattern to it, that type of digital signal processing DSP is currently used for radio communications and sound analysis. When I worked as a wildlife biologist, I used to use a bat detecting system that would analyze bat calls and it could filter out other signals and noise using DSP algorithms to enable it to identify various bat species by their calls.

Too bad Minelab didn’t get the patent on these, they would’ve been awesome coils! https://www.hammacher.com/product/metal-detecting-sandals

Wireless coils would be expensive and very limited. And the used market for wireless coils will be very risky, internal lithium batteries and more electronics to go bad. That would be a terrible idea.

So you give me an idea, I collected a big chunk of that hematite that was giving me issues. I’ll have to try out that experiment as well.

I’ve tried ground balancing on top of a hematite rock, but that was like putting it over a solid iron plate, it was way too big. I will try putting it over a collection of smaller ones with soil, and bump up the SAT to 2, that sounds like a good idea, thank you for the suggestions! I really like ‘your’ detector and appreciate all you’ve put into it. It’s done really well in some of the areas I’ve taken the gold monster to where it had issues with hot rocks and I guess what you would call cold rocks mixed in. I have since sold my gold monster and haven’t regretted that one day. This thing has become my gold detector of choice and my Equinox has been my coin and relic detector ever since I got it.

You know what this means? The GPXRF coil is coming and there will be no more lead detecting! 😁

Good grief, I was so intent on finding small gold that I didn’t even think of trying a different coil! I think you’re right, you were using the DD in that stream bed that you posted about earlier, right? I have to go read that post again. I think you said you were using metal discrimination as well?

Oh my, that’s a bunch of carrots Simon! I was going to say I keep mine on one of those retractable keychain holders clipped to my collecting pouch, That way I use it and just drop it and it retracts by itself back up to the pouch, but it looks like you came up with a good solution for when you pull a bunch of them out of the garden!

That was a good experiment Simon, and I found similar results with mine. I always use the 6-inch over the Coiltek, and have even considered selling it. But you do have a good point, that tip would be useful in several situations such as getting it down between cobble on a stream bottom, and sensing a bit deeper under boulders and in narrow crevices and ledges. As for using the 11 inch coil for gold, it certainly does sense things deeper than the Coiltek or the 6 inch, and it can pick up small stuff, but most likely not as well as the other two can. I’m pretty amazed with its performance though, I found a pulltab in a sandy stream bottom over a foot and a half down once that the Coiltek missed, that was impressive.

I was recently using my 24K to detect in an old drywashing area littered with hematite hot rocks and it was quite difficult to gain any ground because they were plentiful and of all different sizes including pea sized in all the tailings and header piles. The ID numbers weren’t coming up when I did hit those so I started ignoring them where it didn’t show up and continued. This method worked as I was able to pick up small bits of lead that did have ID numbers. It was pretty slow going andI finally switched over to my 3500, but if there was any small gold present I might’ve missed it with that as well (at least I know there aren’t any larger nuggets there). I plan on going back there With my Vlf when I have more time. So I’m curious, what setting or technique do you do with a vlf when you encounter this situation? I tried lowering the sensitivity as low as five which helped a bit, but it was still overloading on some of the rocks. I lifted the coil off the ground as well when I did hit a target which seemed to help. I was also using my smallest coil already also (6-inch).

Nice finds! Cows are trouble. They could have damaged even more than the tent. We had to report a cow licking incident to a rental agency once. A whole herd of them were standing next to the work truck when a coworker returned to it; they found that the cows licked the paint down to bare metal all over it! Glad you weren’t sleeping in the tent when that happened!

There are free 3D printer design files on thingverse here https://www.thingiverse.com/thing:4106131 for folding Equinox head mounts, in addition to coil ear stiffeners if anyone has access to a printer.

I just heard back from Doc. Yeah the markings on mine are gone and he commented that the switch position is not reliable, it would have to be tested under a load. He described the pin outs for me so I could test it too. What a great and helpful guy!

Back in the early 80’s, a construction site got robbed of a lot of blasting camps and explosives, some of which were used to blow up the Harvey’s casino at Stateline, NV. Well the perps supposedly dumped their extra caps in the headwaters of a reservoir where I once worked, so when the waster level went down for the summer, we found hundreds of electrically fired caps hanging on old once submerged trees and boulders. It was a mess and we helped to collect them for the SO to detonate. They were pretty powerful and shot shrapnel around from the metal casing when fired. I wouldn’t keep one of those things around, you should give it to the SO or put it in a hole and burn it (a safer way to get rid of TNT, etc.)

Ok, this should help- I need to know on a Doc’s Gold Screamer (with toggle switch model) what direction to set the toggle to for my GP 3500:

Thanks for the reply/ no white mark though- what is it for, voltage? Any idea what direction it should be? I will post a photo for reference.

Ah, I will have to check voltage then. I should also ask one of the “older” (more experienced who may have had one) guys here too. I tried googling it and watching an old Doc’s and AZO video also but they don’t mention it either.

Hello, can someone explain what the toggle switch is for and how it works on the GP series gold screamer? I recently got a GP 3500 that came with one, and for the life of me I can’t figure out what that switch does. Thank you!

I’ve also seen ripple marks with black sand between them at the beach, that may be part of it too but you are probably right, his targets are buried in it. What I meant about the settings issue about his detector was maybe it’s not working correctly due to how he’s using and setting it.

I posted a geology link above about ripple marks, and wonder if his coil flooded or something. He should test it with known targets. Hope it was just a settings issue!

Hello, are those ripple marks in the sand you drew or how your detector sounded? Test it out on some targets you bury to see if it is working right, maybe your coil is faulty?
