Have you ever found yourself over a reef while fining and experience surge that causes you to damage the reef? Reef Sticks are commonly used by divers to control their buoyancy over the reef. The reef stick is there to keep the diver off the reef. These reef sticks are made of corrosion resistant stainless steel rod. Included with the set are one small 9" (22.9 cm), one large 16" (40.6 cm) and a stainless steel small double end snap. The top end of the Reef Sticks has a loop for attachment to the double ended snap. Snap easily attaches to BCD accessory D-Ring for quick access. Reef Sticks are made in the USA and come with a 60 month limited warranty.
