Well so far i have got out a few times with the Tiger Shark on the beach. Dry and wet sand as well as in the water waist deep. The machine is a work horse and will produce. The discrimination is very fine in adjustment. Some of the high doller discrimination machines have some form of ID but its so wide your going to dig it anyway. The depth seems to be on par as well as finding small stuff. It will false in the water and surf but you can tell a good signal from the little false squaks. The only real problem im haveing so far is getting it to balance on the wet sand. I may have to adjust the internal sensitivity to see if this will work. Next time out is going to be a controled setup and testing and we'll see how it go's.
