Anchors Anchors help you stay where you are. Useful for diving and kayaking when you want to venture away from the kayak or when you are hooked on a fish. In general, our 1.5 lb anchor is used to hold the kayaks position during snorkeling and freediving. Anything over 3 lbs is sufficient to hold your position. The drift shoot allows kayakers to reduce their drift in windy and strong current conditions. Anchors are also used to position your kayak in the direction you want; the drift shoot is used to properly position your kayak in the current.
