How the BIO-FIN Works

Bio-fin provides lift and propulsion with less effort and more power.

Unlike old style fins, which "push" water up and down, the Apollo bio-fin provides power, lift, and forward thrust on each stroke.

The bio-fin directs water flow over the leading and trailing edges of the fin blade.

The result is lift and acceleration just as in an aircraft wing.

Natural Rubber Is the Best Material

Additional Kinds of Propulsion

Apollo bio-fins have the advantage of 2 additional kinds of propulsion in comparison to blade or paddle fins.

Firstly bio-fins have great downwards force propulsion generated during the down stroke.

Much the same as your classical style blade or paddle fins.

Secondly the bio-fin creates additional propulsion when water pass's through the split blade during both the up and down strokes. This is "lift".

Due to its flexibility and ease of use the bio-fin also generates similar propulsion on the upstroke that can't be achieved by the blade or paddle fin styles.

In summary, the bio-fin is propelled by both up and downward propulsion, and then this speed accelerates even further with lift.

Fins Stoke Efficiency

The new bio-fin works like a propeller-fin ™ , and is far more efficient than the traditional paddle style fins used by many divers today.

The propeller-fin ™ design improves the fin's effectiveness while reducing the amount of energy the diver must expend while finning.

Speed, comfort, and maneuverability ... you can have it all!

Extensive field-testing showed that participants were able to reach and sustain higher speeds when using the bio-fin than with conventional paddle style fins.

Voted "Best Overall" (2001-2005) and "Testers Choice" (1999-2005) in Rodale / Scuba Lab USA's annual independent fin review.

BIO-FIN - Ergonomic Design

The bio-fin is designed with a 20º angle to accommodate a diver's natural tendency to bend slightly at the knees in addition to the obvious bend at the ankle.

This angle is crucial to top performance and comfort.

The result is better propulsion and the least amount of stress on the body.

Apollo's choice of superior material and intelligent design provides divers with quick acceleration and the ultimate in power, speed, and comfort.
