Make that two. On the Deus, how do you add your own programs. Do you chose one of the preset programs , make adjustments and then how do you save it?. I read the manual but its kind of confusing to me. The e trac was easier to program imo. Second is the coil water proof or not. I want to use it at the beach in the shallow salt water. I don't see it being dunk in the water in the vids. Kind of leary about dunking it in the water since these coils are expensive to replace. Thanks for all your help. Albert
