Hi DeeCal,
I use my MXT on the wet sand & very shallows at the beaches in Daytona Beach, Fl. I usually run in the relic mode, Gain at the preset or just above (you may need to play with the gain a bit depending on your location),ground lock AFTER balancing in the "SALT" mode, "Dual" dial at about 2.5, Threshold JUST barely audible, and the trigger in the forward position. While not as good as a "underwater" detector I have no problem finding targets down to abt 10". If you are hunting the surf line, lift up the coil above the water when the waves come in. If you don't you WILL get the "OVERLOAD" alarm & it WILL definitely get your attention !!! When changing from dry sand to wet you will need to ground balance in SALT & then switch to Ground Lock. Do the same when going into the water. Note that the MXT is a bit "noisier" than some others but quite tolerable. I love the MXT and think it is one of the best and most sensitive detectors out there. I'm quite pleased with its performance. In just one month of using it on the beach, I've found abt $30 in clad, 5 silver rings, 1 gold ring, 2 gold braclets, watches, etc.
