Hi.........I'm still waiting for my silver uMax to arrive from Dixie metal detectors. I know the boxes on the uMax are not water proof so i don't want to get it wet but the uMax manual says you can put the coil in water. So there saying you could use it shallow waters without a problem? Have any of you with silver uMax's used them in water with any luck? What about shallow ocean water? Thanks for your help.
