Just don't dunk it when you go to dig. Listen closely to what sandman said, because if you set the detector down wrong water on the coil and shaft will run right down the shaft and into the coil connector. If freshwater hunting really interest you get a Tiger Shark and then you won't have to worry about getting it wet. If you want a good price on Tiger Shark use one of our forum sponsors like Miller MDZ. If you call him he can give you a great price.
