SCUBAPRO's Jet Fin set the standard for power and durability when it was first introduced 50 years ago, and it still holds true today. The distinctive fin design sets the standard for power and durability with its sturdy rubber construction and beefy shape. A proven vented design decreases drag on the upstroke and enhances thrust on the downstroke, helping you go farther faster. Find your perfect fit with the self-adjusting stainless-steel spring heel strap, which conforms snugly to your foot. The Jet Fin is ideal for tech divers, deep divers, military divers, commercial divers, dive instructors, and old-school recreational divers. Driven to constantly innovate and improve the diving experience, SCUBAPRO builds high-quality equipment for the work, sport, and lifestyle of people whose passion is found below the surface.
