Twin Jet Scuba Diving Fins Large (9-12) Black

Twin Jet Scuba Diving Fins Large (9-12) Black. This secret lies in the patented design, which allows water to flow between and around each of the twin blades, which flex independently to produce propulsion in much the same manner as a propeller. Blades are also angled to provide symmetrical power on both up and down strokes to achieve seamless propulsion. Patented split-fi n propeller technology - proven to deliver more forward motion with considerably less effort than traditional blades. Drag-reducing vents substantially decrease resistance on both up and down strokes.

Result: more power with less effort and drag. All split fins employ a truly remarkable propulsion technology that uses an unconventional hydrofoil shape to produce forward motion with considerably less effort than any other conventional blade. All our stock ships from US-based warehouses.
