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.
