Split fins have become the most popular style fin in diving today. Just look around when you are out beach diving or on the charter boat and you will soon discover that more divers are making the switch to this style fin. Why are they so popular? They are popular because they work, and you, work less! A split fin performs more like the combination of a whale's tail and a propeller. When you kick the two separate blades twist and create more of a propeller surface which will increase your propulsion and lift. You feel as if the fin is not strong enough to keep you moving as fast as you are accustomed with your full bladed fin, yet you cover the same distance in the same time. Less Drag, More Thrust and most important Less Strength is Used. The Split Fin Design is not only unique; it uses the Latest Technology in Composite Plastic Polymer Materials to give a Light Fin (Great Travel Fin) and one that Increases Thrust and Reduces Fatigue. Extensive R&D and Testing yielded the perfect formula of Flexibility and Rigidity for Efficient Propulsion. Atomic Multi-Composite Plastics result in a Powerful Kick that requires Less Effort, Stress and Strain meaning Less Air Consumption. The Power Rails are Highly-Resilient and Perform as the Backbone of the Split Fin, Storing and Releasing Energy with Every Kick. The Semi-Ridged Flex Battens set in the Soft Elastomeric Blade, Control the Precise Wing Shape to Optimize Thrust and Reduce Drag.
