My first detector was a Tracker, I then bought an ACE 250, then a BH Pioneer 505 and finally bought the AT Pro. I really really liked the BHs. They are so light and the tones are very easy on the ears and soothing and compared to the others they were just as accurate on coin I Ds within depth range. My complaint was not a single silver coin with the BHs. After many air test telling me that both BHs just didn't come close to the Garretts I built a test garden in my yard to make it official. I planted silver dimes and quarters at six and eight and ten inches deep in moist soil. Neither BHs would see any of the coins not even the six inchers. The ACE 250 with stock coil gave a perfect sig on the six inch dime and quarter and silent on the 8 inch dime and jumpy on the 8 inch quarter. The AT Pro with stock coil gave a clean signal on the ten inch quarter and eight inch dime but was silent on the 10 dime. I recently redid the dime at ten inches and started backing off the ground balance till i could see the dime at ten iches. This works in my soil. Auto GB was 73. When I backed it down to 60 I could see the dime a 10 inches. Like many have said here. Knowing your go to detector like the back of your hand is a must. But you need a unit that will get you at least down to the six to 8 inch range to find older coins (at least where I live and hunt). The AT Pro will do it for you when you get it learned good. Give it time and you will learn to love it.
