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. Fin is equipped with EZ-LOK Squeeze-Style" Quick-Release Buckles which Snap-On-and-Off with Ease, yet Will-Not Disengage- Accidentally, and the Spring Strap that Automatically Compensate for Boot Compression and Adjust with changes in Depth. The Spring Straps are Rust-Resistant Stainless Steel Springs were designed with Variable Pitch Geometry. Divers get a more Comfortable Fit and Easy One-Hand Removal with the Large Rubber Thumb Loop, yet the springs are Resistant to Deformation if Overstretched. Included on the "Smoke on the Water
