The BLACKFIN Sand Spear combo is all you need for anchoring in shallow water. the sand spear was designed to keep your board in place while fishing atop a sandbar or in other shallow waters. Simply push the spear down into the sand or bottom until it feels secure. Use the BLACKFIN Push Pole to navigate shallow waters or free yourself if your fin(s) gets stuck on the bottom of the lake/river/sand bar. The BLACKFIN Sand Spear attaches easily by removing the paddle blade from your current paddle and replacing it with the Sand Spear. Learn more here. Please Note: The Sand Spear and the Push Pole attach to the shaft of your paddle, transforming it from a paddle into a spear. In order to have BOTH a paddle and a sand spear at the ready, we recommend purchasing an extra paddle. Shop paddles here. Height: 34.5" or 87.6cmWeight: 0.5 lbs or 0.22 kg
