Here’s another one to add to the “only found in Florida” list… Shark Shield’s. This Australian invention is only available in one store in the US, and its located in Tampa Bay. The shark shield is worn around the ankle, or put on the back of a surfboard, with an antenna which faces towards the back of the swimmer or surfboard. The device uses an antenna which emits electrode signals, which claim to deter sharks in the area by creating an underwater electric field. The device does not harm the sharks, according to Shark Shields General Manager Amanda Wilson, “[Shark Shield] doesn’t cause any long-term damage. [Shark Shield] just causes the muscular contraction of their snout. As soon as they’re outside of the field, that spasm stops.” The device costs about $600.00. Although it sounds like something out of a sci-fi movie, I can see this bringing plenty of peace of mind to divers and scuba divers who spend a lot of time in the water.  MORE
