I got the GT about 2 weeks ago and notice that it falses in the wet sand even when Sens is turned down to 3:00 position. I am hunting Jacksonville Beach. Do you guys hunt mostly in AM Mode rather than Discriminate on the salt water beaches? I run iron mask, volume full clockwise, sens 3:00, threashold just bearly audible, Discrimination at notch 3, no notch. Dry sand no falsing. My Mxt falses less then the gt in wet sand. Wondering?
