HOW SPLIT-FINS 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-Fin TM 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.
