Hello Tim
I picked up the Gold model, arrived last Friday so haven't had a chance to use it for relic hunting. Do have a couple of days off coming up soon and if all goes well will hit some old dirt, hopefully hit a couple of sites give the gold a chance go find stuff we missed before.
Haven't ruled gold jewerly or coin hunting out been hitting parks and such before going to work. Have a feeling its going to be great for gold jewerly, haven't found gold jewerly yet but the tiniest finds its getting is amazing. I feel a thin gold chain will eventually surface, Have the patience so its just a matter of time.
For the most part the Gold would be for serious relic hunting and from what I'm seeing should be an excellent gold nugget detector especially due to getting more depth on the tinest finds. Here's something I am noticing with the Vista Gold on some signals close to the iron breaking point, now these are pieces of foil and if iron disc is too high they will read as iron or a combination of both Ferrous and non-ferrous. In this case a user needs to reduce the iron level because micro jewerly can be disc out, I set my iron disc at 9-o'clock which is the first marked setting. Sometimes even run it with iron off my Gold still discriminates smaller iron in the off position, and this may be my future regular setting for gold jewerly hunting running with iron off full counter clockwise to get thin chains and such.
From air testing, compared the gold with the T-2, MXT with the 6"X10" DD elipcial and AT-Gold with 8.5"X11" DD. The Deep Tech Gold was hitting stronger and deeper on a gold nugget, Even high conductive coins were deeper, should have been the opposite due to the 25khz but its hitting them stronger.
Anyway, have allot to learn but everytime I use the Gold brings me one step closer to mastering it.
Take care,
