The Sharkbanz 2 product is a personal deterrent device. The deterrent field is approximately 3-6 ft (1-2 m). The unpleasant deterrent sensation becomes intense for the shark at about 3 ft (1 m) and becomes exponentially greater each inch/cm closer to the Sharkbanz.
People seeking to be within range of the Sharkbanz' deterrent field should wear their own personal Sharkbanz, either 1 on their preferred ankle, or 2 units - one on their wrist and the other on their opposite ankle.
