Atomic Split fins are certainly the Gucci of the split fins range. 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.

Reviews
A speed demon on the slalom course, Atomic's SplitFin is pretty fast flat out too. This robust fin's rather stiff, longer-than-average blade doesn't fold up in a power stroke like some other splits do - good for when that eagle ray flaps in out of nowhere and you want to accelerate. For close work, the fin is both nimble and efficient despite its length. A well-shaped foot pocket ensures stability and comfort. We found the SplitFin to offer the best buckle system of all the fins we tested, with a special buckle that slips over a mounting post on the fin. To detach, you simply squeeze both tabs and slip the buckle off the post. To attach, slide it onto the post where it clicks into place. Couldn't be easier!

FOOT ROCKETS - SCUBALAB FIN TEST
RODALE'S SCUBA DIVING MAGAZINE
JULY 2003

The first time I tried Atomic Aquatics' SplitFins®, I knew that my ideas about kicking would have to change. These fins ate up distance without hard work. Due to a lack of ankle strain, I felt like I was wearing no fins at all. The most dramatic difference that I noticed was when surface-kicking on my back. My legs felt much lighter on the upbeat and follow-through with the SplitFins® than with paddle fins. I also found that the SplitFins® work best with a short, fast kick as opposed to a long, slow one. It isn't often that a revolutionary product comes along that changes the way we dive. The SplitFin® is one of those products.

While it excels in performance, no other adjustable fin comes close to the scores Atomic earns in fit and comfort. The foot pocket maintains a grip on your foot that virtually eliminates wobble. Even female test divers were able to achieve a good fit.

Kicking out from shore requires power and acceleration and the Atomic SplitFin delivers both. The best buckle system in the business makes it literally a “snap” to put these fins on and take them off when entering the water. And a well-shaped foot pocket ensures stability and comfort.

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.



How SplitFins work



Your conventional paddle fins are just that. They work by pushing some of the water rearward like an old paddlewheel 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-FinTM 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.
