Monte -
Thanks for the advice and all the thought that went into the reply, much appreciated. I am relatively new to the hobby and purchased a BH Platinum a few months ago. So far it has been mostly parks, sports fields and a couple of cellar holes for me. I still have a lot to learn about the hobby and the Platinum.
I was just doing a little due diligence in planning for a future upgrade in equipment. I travel quite a bit throughout New England in my work and am interested in a versatile machine. I like the Platinum in most respects, it is more of a Teknetics than a Bounty Hunter, that's why the question about T2 v G2. The Platinum seems to have trouble identifying targets accurately if more than 2-3 inches deep; a nail can bounce from iron through pull tab and all the way into the coins region on each swing. It also has trouble seeing a coin smaller than a half dollar at 5- 6 inches. Like all hobbies, always look for the next best thing!
Thanks again for all the info.
