Atomic Aquatics Open Heel HEC Splitfins with Spring Straps Designed for divers who demand performance and precision, the Atomic Aquatics High Energy Compound (HEC) Open Heel SplitFin pair a high-performance compound with the trusted Atomic Aquatics Spring Strap Assembly—delivering unmatched comfort, control, and buoyancy. SPRING STRAP SYNERGY The integrated Atomic Aquatics Spring Strap Assembly ensures a secure, adaptive fit that moves with your foot. This system allows for quick donning and doffing, while maintaining optimal positioning throughout your dive. When paired with the fin’s buoyant compound, the spring strap enhances hydrodynamics and eliminates unnecessary drag—making every kick count. HIGH ENERGY COMPOUND ADVANTAGE Crafted from a lightweight, high-energy compound (HEC), the HEC SplitFins remain neutrally buoyant in both fresh and salt water. Unlike standard compounds that sink and strain your kick cycle, this advanced formulation boosts thrust and reduces fatigue. Originally developed for elite divers, this compound is now featured in Atomic Aquatics’ boldest fin design. PERFORMANCE MEETS STYLE Whether you’re navigating coral reefs or gliding through kelp forests, the HEC SplitFins deliver high thrust with low frequency kick cycles, making them ideal for long dives and strong currents. The sleek design and premium materials reflect Atomic Aquatics’ commitment to innovation and underwater excellence. Engineered for divers who demand precision, comfort, and performance, the Atomic Aquatics HEC SplitFins combine a buoyant, high-performance material with the trusted Atomic Aquatics Spring Strap Assembly—delivering unmatched control and effortless propulsion.

SPLITFIN PERFORMANCE The split blade design of the HEC SplitFins delivers high thrust with low frequency kick cycles, making them ideal for long dives and strong currents. The split fin channels water efficiently, reducing resistance and enhancing speed with less effort—perfect for divers who value both power and endurance. __ Aerodynamic, Hydrodynamic, Simply Dynamic Not all SplitFins are the same. Atomic Aquatics SplitFins have a flexible blade designed with Propeller-Fin™ technology so kicks feel very easy and slice through the water with very little drag. Even fish envy SplitFins when divers efficiently swim with more propulsion and less effort. And that means less air consumption. FEATURES Power Rails The highly resilient power rails perform as the backbone of the splitfin, storing and releasing energy with every kick. Proprietary and exclusive to Atomic Aquatics, this material will not deteriorate or lose its resiliency. Flex Pattens Semi-rigid battens set in the soft elastomeric blade controls the precise wing shape to optimize thrust and reduce drag. Split Blade The split blade deflects with the slightest kick to form a pair of wings that slice through the water with reduced drag, propelling you forward. High Surface Ratio Blade Large surface area blade improved pivoting, turning and alternate kicking styles. Hinge Points Thin, yet strong and highly flexible hinge points between the semi-rigid battens cause the blade to react quickly and efficiently to the slightest kick. Anatomically Correct Foot Pocket Contoured to fit your foot without stress points, with semi-open toe for added comfort. Power Plate Internal sole plate creates rigid platform beneath the foot for greater power transfer to the blade yet allows soft, comfortable foot pocket. EZ-LOK Buckle System Totally new, patented buckle system design features easy, one-handed quick release of the buckle from the fin. Re-attachment is simple and secure. U.S. Patent #6,463,640.
