White's 24K Issue?

I am new to gold prospecting and nugget hunting and just recently purchased a new Goldmaster 24k. To learn more about this endeavor I have been reading as much as possible on this and other forums. I have read comments on this forum that one advantage of the VLF detector is its ability to discriminate between gold and junk in areas of past or historic mining activity. And I have also read that the conductivity of gold will vary depending upon its purity. At the risk of sounding dumb and having missed the obvious, my question is this: How do I use the VLF to discriminate, find gold and avoid the trash in a trashy area that may have iron scrap, bird shot, empty 22 shell casings, aluminum foil and other modern and old trash? Thank you to all of you in advance for your patience and help.

I watched the youtube video of the guy from whites demonstrating the iron discrimination ability to wrap around to the 99 range by pressing the lock button while in discrimination mode. However, on my gmx it keeps only adjusting the ground balance offset, which is what happens normally when you press and hold the lock button. Any thoughts on what I am doing wrong? Id love to knockout 99 numbers. Nate

With all the money Minelab made in Africa it seems they should give this machine a good look since it is a very good machine for gold.I would like to see them bring out some epoxy filled coils too in a lot of different sizes. A 9 by 12 concentric first for water hunters or 8 by 11 dd .

False signals every time the coil touches anything. Twigs above the coil touch the wire that plugs into my coil and it gives a false signal. If my coil touches the ground while I sweep I get pounded with false signals. I’ve cleaned the coil, lowered sensitivity, raised and lowered Vsat, locked ground balance and manually grabbed ground, discriminated. I’ve tried new frequencies, factory default, but it won’t stop. Any bump gives a signal. Any suggestions? My first nugget is so close I can smell it! Here are my last finds after 3 or 4 hours but had to stop due to the chatter from my detector.

When I use my Gmx with the 6' concentric coil in a beach section with a high concentration of black sand it is overloading all the time and I have to raise coil about an inch to have it go away.I then go for the nice zip sound and I usually get a coin because all the light stuff has been swept away. This 48kz machine is very hot with this coil.Would a bigger DD coil stop this overloading?
