This float has a bladder made of PVC material. It comes with 17m of orange rope + “Fox” flag, available in round or torpedo. The lead pocket has to be hanged on the edge of your double bladder buoy. When you place a 2kg weight inside, the buoy rise up like a beacon for a better visibility and safety on water. This beacon mode is usefull for spotting a rock or a drift hunting area. To get the buoy back to regular torpedo, just stuff the 2kg weight in the internal bladder of the buoy. This float is the perfect utility float for hanging gear from or marking a dive spot.
