well, i use to hate the beach using the 11"dd coil, but i would run a 80 sens, 40 disc, +2 tone, manually ground balance, and set up the all metal mode with my hum at -3.........now, you get your salty chatter, but i would listen for the change in pitch tone and dig the solid signals......i use the 5.5"dd coil now at the beach and i run my sens at 99, disc at 40, +2 tone, any ground balance and you get no chatter at all with the small coil! i live in maine and im not actually digging in the fine beach sand but small pebbled rocky beaches that have old pilings there that once was a wharf, pier, or dock........alot of iron there too. salt turns the copper green, the silver a grayish color, but ive taken some old coins there as well as a 1857 hard times andrew jackson token......hope this helps........anyone planning on some salt water beach hunting should get the small coil as its a coin magnet much like the 4.5" sniper coil for the ace-250......art
