I narrowed it down to these three. Omega, AT Pro, and Whites Mx5. Live in Maryland, hunt coins and jewelry, Have mild soil, don't do water hunting, but maybe occasional beach, 68 years young. and have detected for 8 years with the ace 250. Give me some opinions but only about these three. ( I 'm suffering already from information overload). I know the Mx5 is new but I like what I read about it. I need information about true depth in mild soil on lets say dimes and quarters. Also depth on gold rings in the ground. I know there is a lot of knowledge out there so please help me decide.
