Prospecting with the Garrett AT Gold Metal Detector

Some facts about Garrett Metal Detectors , and today we’re up here in gold country with the new Garrett AT Gold. We’re out on these dredge tailing piles and the reasons that they’re here is because of that water. Those dredges couldn’t get anywhere other than the valleys and the cricks down below in the rivers is what allowed them to get up here, forming these dredge tailings. What we’re trying to do today is find some of the specimens that the Boise Basin has. We don’t have a lot of big gold up here as far as nuggets, but we do have some pretty good size specimens. Again, a specimen is quartz with gold in it. What we try to do is hunt more of the gravel piles, the finer materials like this here.

The reason is because there’s going to be more smaller pieces than in these bigger, rounded rocks over here, like the cantaloupe size and above. Most of your smaller pieces of gold are going to work their way down in there and that’s not good because of the machines lose depth and sensitivity. So, when we hunt the finer gravels, that’s where you’ve got a better chance of finding the gold. One of the other great features about the AT Gold is it’s waterproof. Having a waterproof machine, and the only waterproof gold metal detector right now on the market that’s VLF, I can take it in the crick and totally submerge it. Not only can I submerge the coil but the whole control box. Yes, folks, that’s right, the whole detector can be totally submerged.

When you’re going to hunt in water, rivers, streams, cricks, always try to get the gravels around the bend. If you see when we get up on top, you’re going to see a bend around the corner. Get on that inside bend where those smaller gravels are. Keep that coil right down on the bottom, slowly moving it back and forth. That’s how you’ve got a better chance of finding one of them nuggets out there or up here in the basin, a specimen. That’s the typical gold that a high-kilohertz VLF machine will find. You definitely want to use a small coil, the smaller coil the better. And, you can get that in a lot of places out west in the gold fields because a lot of the machines will miss them.

Especially pulse induction detectors. You start getting a little bit bigger pieces of gold, something like this that’s probably a couple of grams, okay, PI machines are fabulous on that. You can get them at great depths of 14, 16 and 18 inches, possibly. But it’s a good, solid, chunky pieces of gold. VLFs will hit that just as well, just like the one on my neck, okay. That was found with a VLF gold machine. But, up here, what we’re looking for is these. Pieces of quartz with gold in them. And lots of times it’s just little speckles of gold. Okay, and they’re in the tailing piles up here.

It’s not what we call a nugget. It’s what we call a specimen.And some of them will have different thicknesses of gold in them. So, that’s what we’re going to be looking for. And hopefully, we can find some of those.One of the features on the new AT Gold is the adjustable iron disrimination. The good thing about it is, we can adjust how much iron we want to discriminate or the size of iron targets. And the reason you want to have that capability is some areas, such as here, where the gold is in quartz, could read a little bit lower. Or, a smaller nugget could read lower.

┬áSo, what I’ve got here is a piece of iron and you can hear the grunt mixed in with the good target. Right now, my iron ID setting is at 40 and next to it I’ve got some quartz with a piece of gold in it. And you notice, even though it’s broken up a little bit, it still has a good, clean signal. Here’s the iron. And here’s the gold specimen. Now, some people say, “How come you can’t clean that up more?” Well, you could and you could miss these. Every detector on the market has a capability of making a false reading at times due to either the size of the target, the mineralization, the depth of the target. So, rule of thumb, when it doubt, check it out.
