Even fish are jealous of split fins
Why split fins provide better propulsion with less air consumption:
We only had to observe the tail fins of fish – the only problem was keeping up with them, as our traditional fins required too much effort. Rigid paddle fins can cause leg strain, fatigue, and cramps. Due to the paddle fins' resistance to stroke, divers often felt like they were moving quickly. However, underwater speedometers showed that these divers were moving relatively slowly. Split fins provide better propulsion with less drag and less effort. The reduction in stroke resistance results in the diver maintaining greater speed, more power, and greater comfort. Independent tests have shown that this design can significantly reduce air consumption.
Not all split fins are created equal. Split fins are available in a variety of shapes, sizes, and rigidity, which greatly influence overall comfort and performance. A fin with short, soft blades is easier to kick than a longer, stiffer one, but requires more kicks to cover the same distance. A fin blade that's too stiff requires too much effort to kick comfortably. The Atomic Aquatics SplitFins are specifically designed to optimize all of these variables. The fins are easy to kick and deliver high propulsion, speed, and power with a comfortable low-frequency stroke cycle.
