I know most people on here are primarily coin hunters. I was hopeing someone could tell me if there is any difference in depth on lead bullets, ex. Civil war 56 cal. minie ball. between the Exp 2, Exp SE or E-trac. They are really trying to push the Fisher LTD as the deepest relic detector in mineralized ground. Still waiting for someone to prove its the best. For now, I will keep useing my Exterra 705 for relics until someone shows me something deeper. Anyone done any relic hunting with any of the top end Minelabs? Thanks, Mark
