I've gone over most of my sites and the year's been slow. Now as I was thinkin' about the situation, I got to thinking (I know, dangerous thing.) So why should I be concerned about depth-and it's probably an overrated topic.. So I come up with this combination: sniper coil (never take it off) - a/m mode-2 bars sensitivity! Couldn't believe I didn't get hardly any iron signals at most areas. And the teeny trash was mostly bypassed-although small wads of foil still came in (gold ring area). It was like using the old TR's only not having to worry about mineralization. Couple of coins at 3" along with a pulltab at that depth for the deepest coins. But the a/m mode made up for any shortcomings as there was no hesitations on the signals. It was simply awesome-I can see a gold ring coming! Also noticed some costume jewelry that was rejected at most settings. I think I'm gonna be using this at my sites all the time-it's really unbelievable. Almost forgot-using Ace 250.
