Split fins come in a variety of shapes, sizes and stiffness which contribute greatly to overall comfort and performance. A fin with short, soft blades will kick easier than a longer, stiffer one, but will require many more kicks to travel the same distance. A blade that is too stiff will require too much effort to kick comfortably. The Atomic SplitFins were specifically designed to optimize all these variables. They are easy kicking fins that deliver high thrust, speed, and efficiency with a comfortable, low frequency kick cycle.

Why SplitFins deliver more propulsion with less air consumption

All it took was watching the tail fins of fish – except that we couldn't keep up with them because our traditional fins took too much effort. Using hard kicking paddle fins can result in leg strain, fatigue and cramping. Because of the kick resistance of a paddle fin, divers often “felt” like they were moving fast. But underwater speedometers proved that these divers were actually moving relatively slow. 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.

Not all SplitFins are the same.

Maximum thrust in flutter, and stability in alternative kick strokes with the latest aerodynamic technology.

Tough and durable natural rubber defies the elements

Adjustable, quick fastening stainless steel buckle system. Generous foot pockets fit all sizes of wetsuit and drysuit boots.

POWER RAILS

The highly resilient power rails perform as the backbone of the splitfin, storing and releasing energy with every kick.

FLEX BATTENS

Semi-rigid battens set in the soft elastomeric blade controls the precise wing shape to optimise thrust and reduce lag.

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 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 your foot without stress points, with semi-open toe for added comfort.

Why Multi-Composite Plastics?

Extensive R&D and testing yielded the perfect formula of flexibility and rigidity for efficient propulsion. Atomic multi-composite plastics result in a powerful kick that requires less effort, stress and strain…meaning less air consumption.

How Atomic Aquatics SplitFins Work
SplitFin Wings “Slice” Through the Water

Traditional paddle fins work by pushing water rearward. 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 required to overcome that drag. The Atomic SplitFin slices through 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 funnelled into and out of the opening (split) between the wings. Drag is reduced, effort is reduced, and efficiency is increased.

Propeller-Fin™ Technology Moves You Faster

Atomic Aquatics SplitFins use Propeller-Fin Technology to deliver ultra-high speeds with a small-range rapid flutter kick. This works in the same manner that increasing the RPM on a boat propeller accelerates a boat to high speeds.

Multi-Composite Plastics And Other Uniquely Atomic Features

The Atomic signature is our use of exotic materials specifically designed to improve performance. We developed multi-composite plastics for the SplitFins to maximize the efficiency of the kick with less fatigue. Flexible side rails and a stiff foot pocket are combined with stiff battens in the blade to control the flex pattern for optimum performance. Our patented EZ-LOK Buckle System is one of those distinct Atomic features that make divers love us even more.

How To Swim With Atomic SplitFins

Don’t worry about how easy the SplitFins are to kick. There is nothing wrong, you’re probably already going just as fast as you did with your old fins. Although they work with a variety of kicking styles, you should adapt to a smaller range, more frequent flutter kick for maximum performance.

The smaller-range rapid flutter kick also keeps your legs within the slipstream of your body so that you punch a hole in the water that is only as big as your shoulders and your tank. Remember, less drag means more speed and less effort.
