Description & Details

IST Propulsion Rubber Fins

F4 Propulsion represents the latest evolution of Military-style Fins from IST.

Based on IST's iconic and military favorite F-1, the F4's wide blade design is slightly shorter – however, there is no power shortage here. That’s because of the expanded width rubber blade which incorporates unheard-of flexibility. Even more thrust is attained by 3 deep vents which force water backwards, emulating the effect of three synchronized turbo-powered water jets.

The F-4 is excellent for open water dive missions, but also shows its skill in assisting diver- maneuverability within confined spaces. As you would expect and demand of a military fin, the F-4 is durable and long-lasting; compatible with IST’s famous Universal clamp stainless steel coil spring fin strap. There’s a reason U.S. Military Personnel have made IST's exclusive F1 Deep Sea Scuba Diving Military Rubber Rocket Fins their number one choice. The F-4 is following the tradition, already a favorite with the U.S. Navy.
