Havillah, I use pro-custom, zero iron disc, nothing notched out, sens 2 down from max. Gb is usually 11 or 12. It will false when a wave swirls around my feet carrying all that sand, but a good target will always come through. I sometimes drop the sens down another notch. I use pretty much the same settings for dry land. I auto gb and run the sens 1 notch from max. It's a busy setup, but I like to hear everything. I dig my fair share of pull tabs and foil, but that's part of the game.
