When did you stock the fish ? Boat mounted e-fishers should only be used by experienced operators - way to dangerous for others and the fish. Back pack e-fishers are for very limited use in small streams and waters and can be very dangerous. As Theo noted seining is a much better method for folks like us as is trapping. Electricity and water when mixed can be a real shocking experience !! \:o

Others here can better address hand crank phone systems.
