Hey you guys I need to ask a question. Can I metal detect on beaches with my Ace 250 although it is not a beach machine? I don't want to ruin it with the beachy elements. And if I can, what is the best way to clean the coil? Can I submerge it in water and clean it that way? Thanks for your help. Oh and another question...if I can do the beach thing can I submerge my coil a little ways in the water as long as I keep the housing box out of the water?
