Omer Sub's Master Torpedo Buoy is made of high visibility orange 420D Nylon with an inside air chamber manufactured in very resistant PVC material. Buoy comes equipped with a removable Red and White Dive Flag for added safety. The Torpedo Float is the ideal Buoy for spear fishing from the shore were surf conditions are present. Its Hydrodynamic shape and removable flag reduces the drag one may experience with a buoy that is round and will create more water resistance when in tow through the surf zone.
