I am over in NWFL. The sand is very similar to that in Gulf Shores, AL. My DFX has never ground balanced in the beach sand since I have had it the last 6 months. There just isn't any mineralization in the sand to balance out. I also do my ground balance over the wet sand. It appears to cut down on some of the false alarms. I have the factory coil and the DD1400. Both beep when they touch the sand.rixdfx said:i used my dfx this past week in alabama....mine wouldnt ground balance on the sand....if i touched the coil to the sand, it would beep....
