My Goodness. I read all these threads about detector recovery speed, mineral reactivity, how an iron nail might hide a nickel, what happens when a aluminum tab is near a silver dime, this mode, that mode, Iron Bias, Auto Ground Tracking, Horseshoe button this, sensitivity, EMI issues, masking, what is the best frequency for this and that, what freqs are transmitted / received in various detecting modes, etc etc etc.
I am SO GLAD I can turn on my simple, obsolete AT Pro and go out and find coins, relics and jewelry. With the mineralization about the same in my geographic area, it is turn on and hunt, Pro Zero, Full Sensitivity, nothing Disc'ed out. Oh... and 1300 silvers, 6500 wheat cents, IHPs, Largies, 9 Silver Dollars, 100+ silver rings / jewelry going into my 7th year of detecting with this machine. I'm not the sharpest tool in the shed, so I am grateful to have a detector that only needs to be powered up to find good stuff.
