Atomic Aquatic’s SplitFin is 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 Split Fin propels you 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 Atomic Aquatics Split Fins virtually eliminate muscle strain, fatigue and cramping to enable you to swim longer distances against stronger currents.
