Hi all!I,m new to this site and to metal detecting in general but am very interested to get started.I don,t have a detector yet but am saving to get one as soon as I can.Got my eye on a Garrett Ace 400.I,m in S.E.Arkansas,Dumas.We have a lot of old tenant and farm worker home sites here that I located by old map study,I,m pretty good with maps and aerial photography thanks to the USMC,was a FO for 81 mm mortars once a long time ago.I,m learning a lot by perusing this site and gaining knowledge about how to proceed once i have my detector in hand.Thanks all of you for your informative posts.Jim Campbell.
