Often incorrectly called a Hawaiian sling, a polespear is an underwater hunting device that doesn’t require a trigger system to deploy. Polespears are one of the earliest tools of primitive spearfishing. The basic make up of a polespear is a long, straight rod. At the front there is a pointed tip. Attached to the rear is some type of elastic or other material that acts as the power source. This elastic material is held by the user and stretched the entire length of the polespear. When a user wishes to “fire” the polespear they simply release the polespear. The elastic then contracts. As a result, the stored energy in the stretched elastic propels the polespear towards the intended target. All polespears work on this concept. The JBL one-piece polespears are made of aircraft aluminum for increased rigidity. There are a variety of polespears on the market ranging from economical fiberglass one-piece designs to advanced models that feature cutting edge materials and design; such as The Shaka. Upgraded features like carbon fiber deliver unmatched rigidity and in turn provide maximum energy transfer for the fastest shot possible.
