Absolutely.
Worn on your wrist or ankle, one Sharkbanz unit will help reduce the risk of an unwanted shark encounter, as the deterrent field of a single Sharkbanz unit is approx. 1-2 meters (about 3-6 ft).
However, wearing two Sharkbanz (one on your ankle; another on your opposite wrist) will increase the overall deterrent field size and thus provide greater coverage – similar to how other safety devices work. If only wearing one, we suggest wearing Sharkbanz on your ankle, as the majority of shark bites occur on the ankle and leg areas.
