tried it yesterday at the beach at Galveston. First I had it on the regular beach program, man sens at about 22, very noisy and chirpy. Switched to the edit to seawater, and it was eerily quiet!!! Manual at 28 still quiet and in water about 6" with water breaking over the coil it never ever made a squeek! Got a dead on, no bounce, 12-13 nickel at 9" and a clad dime at about 5". Set another coin program as the flip and it did well but was noisy.
I wonder what would be the result if one could modify the 'beach' program with 'seawater' to a dry land trashy area program, with all the stuff like gone huntings??? I think I will do that and save it as a 'salt coin" program and see if there is any benefit to it.
