E-Shark Force show info...

E-Shark Force is used by scuba divers and snorkelers, surfers, ocean swimmers, and Stand Up Paddlers. It is safe for marine life and safe for human life, too. The electronics emulate a defensive system found in certain fish that naturally keep sharks at bay. The E-Shark Force Device keeps sharks at bay without hurting them, either. When they get within range of the device, they just prefer to leave, quickly.
