A Little GPZ Gold - Part 2

01 Jul 2015

Following on from Part 1 of this blog which covered how I use a GPZ  with GPS to cover ground more effectively, I'd like to share some more techniques and detector settings I use for finding gold with my GPZ 7000.

I continue to follow the various posts around the world about the GPZ 7000 and people's experiences with it. Mine are pretty boring. I turn the machine on, maybe do a quick ground balance routine, and go detecting. I may not even go through the ground balance motions. I just turn it on and pick up from where I left off the previous day. I usually run in High Yield, Normal Ground, Gain of 12, Smoothing Off, Ground Tracking On. I leave most audio settings alone. The detector will often run noisy with these settings, especially in alkali locations. I may lower the threshold to 20 to knock out some excess noise, or just lower the overall volume level using my headphones. The GPZ lacks a master volume control that lowers all sounds at once, and so benefits from the use of an external booster with master volume control. The problem for me is that is one more battery operated gizmo, and so I often just use my headphones instead to gain the overall volume control I crave. I tend to run my detectors noisy but like it to be quiet/noisy not loud/noisy.

When the ground responses get a bit much, as is the case with ground salt, I react more by slowing down and modifying my swing than changing detector settings. So far I would say about half the gold I found was pulled out of fairly high salt response ground with the attendant moaning/groaning or hee/haw responses the GPZ produces in that type of ground. That seems to be a show stopper for a lot of people but I don't pay much attention to it myself. I have this theory that killing those responses might kill my gold finding capability on this ground to a certain extent, as I know some of these locations have seen other detectors that ignored the salt. They also missed the gold. Coincidence? Maybe. I have plans for more experiments regarding this but have had a hard time tearing myself away from my limited detecting time to do more comparative tests. Later.

Anyway, I have quietly picked up just over a couple ounces of gold with my GPZ 7000 so far this spring. The largest nugget is 3/4 oz and there are several other nice pieces I am very happy with. Nice solid, clean gold, my kind of stuff. An odd mix from very worn appearing to rough. I am unfortunately getting waylaid again with things I must attend to before I can go prospecting again and so I decided I may as well post this update now. It could be weeks before I get out prospecting again. Until then, here are some happy pictures to enjoy.
