The Atomic Aquatics SplitFin

A radical new approach to diver propulsion. With the slightest kick, the split blade deflects to form a pair of wings that slice through the water with reduced drag, creating lift in the forward direction to propel you ahead. Compared to conventional fins, the SplitFin swims with less effort, stress and strain resulting in greater sustained speed, power and comfort. Independent testing has shown that this design can significantly reduce air consumption!

Why SplitFins are better than regular fins

Because you can swim faster and further with less effort, stress and strain! Compared to the conventional style fins that you probably own, the SplitFin operates more efficiently that the "paddle" type fins that you're used to. They deliver more propulsion with less drag and kick with less effort. Using hard kicking paddle fins can result in leg strain, fatigue and cramping. This reduces your ability to sustain high speeds for long periods of time. A fin that is hard to kick is often falsely perceived by divers to be an indication of power. However, tests with underwater speedometers show that these divers are often actually moving relatively slowly, even though they "feel" like they are moving fast. Kicking effort has no direct relationship to speed or power.
