I tried your setup tonight in my yard... After 20 or so hunts... I guess I've about got it all! LOL Oh my is that a noisy program. I'm getting tones nearly every half step. I dug a total of 9 rusty nails and one modern nickel. If you were to open up the right corner on the coins program and continue to discriminate out the high # Fe's the way the coin program does... What is the best way to get good depth and still keep the discrimination of iron and maybe quiet the program? Any suggestions. I noticed that in air test, that the basic coin program tends to poop out at about 8. What adjustments would you recommend to get to the ~10-12 range with the coin program?
