FORCE FINS for...

SCUBA
and
Free Diving

Extra Force Fin is our most powerful scuba diving fin. Thrust and efficiency are maximized when the water is channeled, focused and accelerated behind a long, snappy blade that's powered by your strongest kicking muscles.

Extra Force Fins feature our toes-free foot pocket that reduces cramping and leverages power from your strongest kicking muscles, for a most efficient and powerful kick.

Clean edges that cut through the water without turbulence. An ultra snappy blade designed to move a high volume of water behind, giving you maximum per kick acceleration.

Sculpted trailing edges and Vortex Generators keep water fast-flowing. Extra Force Fins are adaptable for optional Force Wings (pictured with Whiskers), which allow you to control the way the water works for you. When rotated inward, they draw water a large column of water to the center and behind you, accelerating it similar to the way in which water accelerates through a gorge, and create a ramjet effect to catapult you forward.
