We have a lot in common. Yep, BFO. Mine was the Garrett Master Hunter BFO with all the accessories...I was in England with the military. Oldest coins...Roman. In the US oldest coin was Chinese. I have had many detectors as well over the years...Garretts, Whites, Fisher, Minelab, Tesoro, Bounty Hunters, and can't think of any more at the moment. Got my start in detecting in the 70s and was a detector dealer/magazine article writer for the National Treasure Hunters League, Mesquite, TX. You might remember Ray Smith...owner. Been in and out of detecting over the years...keep coming back lol...I am hooked. We also seem to have the same Son as a Brother and the greatest Father anyone could have.
