Full-foot model of the Atomic SplitFin is lightweight yet delivers results comparable to the larger open heel fin for snorkeling or scuba diving. Proven to be the highest performing full-foot fin in the world.
Sizes:
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!

Designed to deliver the highest performance ever achieved by a full-foot fin, the Atomic Aquatics Full-Foot SplitFin meets and exceeds user expectations whether being used for snorkeling or scuba diving, and has proven to be the highest performing full-foot fin in the world. Using the patented Nature Wing design Atomic Aquatics has added a unique light-weight batten and blade design that delivers incredible performance and more power.
Scuba divers traveling to remote warm water destinations choose the full-foot model because it's extremely lightweight, more comfortable, very attractive and simpler to transport. The fins are easy to pack and dont take up as much space as traditional, heavier open heel fins.
The performance it delivers is simply amazing making this model a favorite among divemasters and instructors in resort areas around the world.
Now theres no reason to carry heavy open heel fins when traveling to warm water destinations.
The Atomic Aquatics Full-Foots dont have cumbersome buckles, are less bulky and even double as snorkeling fins when desired.
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.
How SplitFins work
Your conventional paddle fins are just that. They work by pushing some of the water rearward like an old paddle wheel steamship. As a paddle fin is pushed through the water, much of the water spills over the top surface of the blade and sticks to it, creating drag. Extra kicking effort is needed to overcome that drag. In contrast, the SplitFin slices though the water with two wing shaped surfaces, creating lift and forward propulsion more like a propeller. Any water traveling over the top of the blade is funneled into and out of the opening (split) between the blades. Drag is reduced, effort is reduced and efficiency is increased. The Atomic Aquatics SplitFins use Propeller-Fin Technology, which delivers ultra-high speeds with a small-range rapid flutter kick in the same manner that increasing the RPM on a boat's propeller accelerates a boat to high speeds.
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. The backbone of the splitfin, the highly resilient power rails, store and release energy with every kick. Propietary and exclusive to Atomic Aquatics, this material will not deteriorate or lose its resiliency.
