The Floatline Clutch is an amazing piece of equipment that speeds the recovery of your fish as well as allows you to adjust the length of your floatline. It autolocks the float in place as you retrieve your fish, preventing them from taking back all your line when they do a second run. It automatically locks the instant the fish puts pressure on the clutch. It can also be used to adjust the length of your floatline. When you are diving a shallow reef you can move your float up your line. Lets say you have a 100' floatline. If you are diving a 40' reef you can adjust the placement of the float so it sits at 40'. If a fish is shot, the clutch will prevent it from taking your 100' line into 100' of water. Brilliant!!!
