 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. 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. How to use the SplitFins Don't worry about how easy the SplitFins are to kick. There is nothing wrong; you're probably already going just as fast as you did with your old fins. Although they work with a variety of kicking styles, you should adapt to a smaller range, more frequent flutter kick for maximum performance. The smaller-range rapid flutter kick also keeps your legs within the slipstream of your body so that you punch a hole in the water that is only as big as your shoulders and your tank. Remember, less drag means more speed and less effort. The SplitFins are designed to produce maximum power with a smaller and more frequent flutter kick. Paddle fins are not. The smaller the range and the greater the frequency, the greater the power and speed. How to swim against a current. The Atomic Aquatics SplitFins virtually eliminate muscle strain, fatigue and cramping to enable you to swim longer distances against stronger currents. Divers have reported being able to make headway against currents they would not normally be able to overcome with paddle type fins. Whatever the speed of the current is, you need to swim faster than the speed of the current to make headway. The true indication of power is actual speed. A small-range rapid flutter kick with the SplitFin delivers the same or greater speeds than any paddle fin without the strain. In order to reach and sustain high speeds, you need to be streamlined. The reduced kick size of the SplitFin allows you to maintain constant speed, power and momentum throughout the kick cycle. In contrast, the wide kick used with paddle fins extends your legs above and below the slipstream of your body creating drag which slows you down just like swimming around with outstretched arms would. In a fast current, kicking any
