Through design optimisation of a fin’s length, stiffness, size, and material, Atomic Smoke on the Water Split Fins deliver high thrust, speed, and efficiency with a comfortable, low-frequency kick cycle. In comparison to a blade fin, SplitFins deliver more propulsion with less drag and kick with less effort. Reducing the stress and strain of the kick results in greater sustained speed, power and comfort. Independent testing has also confirmed that the SplitFin design significantly reduces air consumption, potentially making for a longer dive.

SplitFins differ from traditional blade fins in the way they work, but in also how the diver uses them. For maximum performance, more frequent flutter kicks are best. This keeps a diver’s legs within the slipstream of their body, making the diver more hydrodynamic. By reducing drag, the diver has greater speed and less effort.

Atomic Smoke on the Water Split Fin Features:

• Power Rails – Stores and releases energy with every kick, as well as channels water to blades
• Flex Battens – Semi-rigid battens set in the soft elastomeric blade controls the precise wing shape to optimize thrust and reduce drag
• Split Blade – Deflects with the slightest kick to form a pair of wings that slice through the water with reduced drag, propelling the diver forward
• High Surface Ratio Blade – Large surface area blade improves 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 the diver’s foot without stress points, with semi-open toe for added comfort
• Power Plate – Internal sole plate creates a rigid platform beneath the foot for a greater power transfer to the blade, yet allows for a soft, comfortable foot pocket
• EZ-LOK Buckle System – Patented buckle system design features easy, one-handed quick release of the buckle from the fin. Re-attachment is simple and secure, and practically eliminates missing buckle pieces or buckle jams
• Spring Fin Strap – Guaranteed to make putting on and taking off fins easier, especially with comfort grip pull loop. Spring Straps also keep the fin fitting snugly onto the boot. These also won’t perish over time like traditional rubber fin straps.
