The E-Shark Force Dive unit is the simplest shark deterrent device on the market, and guaranteed to work well. It wraps around the ankle of the user, much like a surf leash strap, and activates in salt water. The Nylon and Velcro straps fit snug when overlapped and can be easily pulled apart by hand, but won't come apart by themselves in the water. This is the unit a swimmer or snorkeler would want to wear, and it also works well for surfers as they sit on their boards, wipe-out or paddle.
The device charges on a small portable charging pad just by being set down on top of it, without having to open any part of the device. Included with the device is a rubber cuff. Some wearers will experience a sensation similar to a muscle stimulator, and this cuff helps block that further. Also, the charging pad can be plugged into a portable solar panel, if the user has one, in areas where there is no ready electrical current. It takes approximately 3 hours to fully recharge the E-Shark Force device. This unit weighs 9.6 ounces, and the complete box weighs 16.8 ounces.
