beach hunting the 505

The couple of times I took my 505 to the beach, the wet sand had me falsing everywhere. How do I fix this problem and still find jewelry and coins? Forgive the question if it is too basic, but I am going to a beach for a short hunt on Saturday. I don't want to waste any time fighting my machine, which works great every other place I have tried it. Thanks in advance.

You can try lowering the sensitivity, but you may not be able to get it stable on wet sand (saltwater beach).
