Gerry in Idaho Posted March 6, 2022 Share Posted March 6, 2022 21 hours ago, Tom T said: I’m new to the monster (thanks Gerry)? so correct me if I’m wrong, but I “think” I’m “hearing” a difference in crispness of tone between different types of targets. It could be that this is just a remnant of memory from my time using the Explorer but gold seems to have a cleaner (crispy) sound as opposed to the “growling” that ferrous signals seem to have at the beginning and end of the tone…it could have to do with the size of target too. I haven’t tested this thought yet because I’m only slightly over a week deep into the monster…Lots to learn Welcome to DP Tom and hoping your new GM-1000 is as productive as you can make it. As for different pitches of the tone on the Monster and between it being iron and nonferrous. Yes some iron targets can give a scratchy or shorter chirpy sounds, but please do not rely on that 100% as you'll get bitten. I've had found tell me they can hear the difference of lead and gold. I call BS. I have folks who think they can hear the difference of bullet casings and gold, again I call BS. With a detector like the Monster and so many other gold machines, you should not rely on what your ear hears as much when it comes to IDing targets and trying to differentiate the difference. Now I will give an example of how my ear can help me ID some gold from other undesired targets. Say a particular site has small half grain of rice nuggets across a bedrock shelf or bottom of a gully and all these nuggets are about the same size. Lets also say a rabbit hunter was in there with a 22 rifle and there are casings scattered on the same area. At that time an experienced ear might hear the signal strength and width of the half grain rice gold nugget vs the .22 shell casing as they are different in size and density. Now if there happens to be a 1 gram nugget mixed in with the smaller nuggets and .22 casings...and you still tried to use the signal strength/width strategy, you'll miss the 1 grammer. Above is a prime example of the Equinox 800's identification capabilities as it will easily read and give different ID #'s of the small 1/2 grain rice nuggets vs the .22 casing. So with the NOX, I get the same signal with/strength and also VDI #'s. But as mentioned by others....when in doubt-check it out. 7 Link to comment Share on other sites More sharing options...
GotAU? Posted March 6, 2022 Share Posted March 6, 2022 Hey Machineman, You didn’t mention which coil you were using for the test - The larger one in Auto 2 will punch the deepest on the GM, yet it is also very sensitive on small stuff. Which coil were you using, both? I switched to the larger coil for soils and only used the small one when directly on bedrock or in tight places. 3 Link to comment Share on other sites More sharing options...

Thanks Gerry, I’m sure it will be. I also have a nox 800 but need to ease into it. No, I’m not going to try differentiating targets by tone quality alone. I’ve already found a little piece of gold in my yard area along with several #6 shot, some foil, screws, solder etc. ETA: I just referred a Robert Brown your way…. 1 Link to comment Share on other sites More sharing options...
IDMineralSurveys Posted March 7, 2022 Share Posted March 7, 2022 I haven't noticed anybody mention something I had learned during a trip to a good gold area in Alaska with my GM1000 - even large pieces of gold, whether shallow (4 in.) Or deeper (10 - 14 in.) typically always read to the iron side of meter most times initially, but sometimes would only briefly blip to gold side. So I ignored the indicator on first soundings, then would get much better accuracy reads by doing a couple extra passes reading strong iron and then immediately turn 90° and check the same target. I found much better accuracy of the meter reads were indicating gold upon turning direction. Iron tagets would still read iron (I dug them anyway) and were verified, but the little blips to the gold side turned up some really nice pieces of gold (72 pieces) - up to 1/4 oz at 14 inches. Later returning to Idaho, I have found this works quite well here also, so it has become a habit to NOT dismiss a target without multiple passes and in multiple directions checking with the meter indication. BTW, brass, aluminum, copper and lead targets read the same indications for me as if gold. 2 Link to comment Share on other sites More sharing options...

Any nugget no matter the size can be fooled by every detector known. There is always a certain depth that ID machines can not properly identify the target. The other thing to watch is the matrix of the soil and the more mineralized the soil the less accurate and depth the ID machine has. Part of the reason I prefer to hunt bigger gold in tailing piles is the lack of mineralized soils to mess with the ID of a detector, especially VLF. On the flip side hot rocks can mask a good chunk of gold as well. 1 Link to comment Share on other sites More sharing options...
Amgminingco Posted November 24, 2023 Share Posted November 24, 2023 I had a signal on my gpz7000 take me down to 2.5 feet which I know from experience in my area generally means huge gold, I swung the monster over it with 4” of dirt cover and it overloaded on iron with that nasty grunt and I ignored it, 6 lb 7 oz specimen with no iron oxides or sulfides of any kind in it. It didn’t swing to the right on the bar until I had the specimen out and put the detector right on top of it. Rule #1 don’t trust it lol Link to comment Share on other sites More sharing options...
phrunt Posted November 24, 2023 Share Posted November 24, 2023 Reacting to the ground I guess, I've never liked the meter on the monster, very unreliable unless the signal is rather obvious. Link to comment Share on other sites More sharing options...
