The Farallon Shark Dart is a unique and innovative product designed for scuba and snorkelling enthusiasts. Created by the brand Farallon, this Shark Dart is a defensive device that can be used to protect a diver/snorkeller from a shark attack. The device accommodates a small compressed C02 gas cylinder which is activated when the dart is stabbed into the shark. The dart can have an extension tube screwed into its base so that there is greater distance between the shark and you. Full instructions are included.
