The choice of the worlds elite fighting forces. Specifications: *Less silt up and turbulence. *Up to 25% reduction in air consumption. *Energy and muscle fatigue reduced by up to 40%.

Not all split fins are equal. Apollo was the first to visualize and introduce the split fin technology to the diving public. There are now more than a dozen alternative split fins on the market. Look closely before you decide. While some are produced with a plastic rubber compound, the Apollo Bio-Fin series is the only split fin produced with 100% rubber.

100% rubber provides a soft comfortable foot pocket and the perfect amount of weight and flexibility for top speed with the least amount of effort and strain on your body

* 20 degree angle of blade ensures that the fin works with the natural resting angles of ankle and knee
* Split fin design allows for more power and less effort than any other fin
* Increased maximum speed and reduced fatigue
* Consistently rated as the fastest fin in the water
* Easy quick release buckle system with finger loop
* Color: charcoal black (pro model) or metallic blue (pro metallic model)
* Sizes:S / M / LL

Split Fin Overview
Speed, comfort, and maneuverability; you can have it all. Extensive field testing has shown that each participant was able to reach and sustain higher speeds when using the Bio-Fin than they could achieve with conventional paddle type fins.

Divers state that when swimming with underwater speedometers or on timed runs along a measured underwater course in full scuba gear, the fins are so efficient that they can swim easily at a relaxed pace without any fatigue or strain.

Improved cruise speeds combined with reduced effort and decreased air consumption greatly increase the distances that can be covered in a dive.

Every level of diver , from the student to the most advanced technical diver, will benefit from using the Bio-Fin.

History
Apollo was the first manufacturer to visualize the benefits of "propeller fin" technology. With any new technology a product must do more than just look and sound good.

The Bio-Fin had to stand up to our claims. After years of product development we introduced the first split fin in late 1998. The lightweight synthetic material was buoyant and fairly rigid. It could outperform any traditional paddle fin!

Our designers felt that the flexibility and lack of buoyancy inherent to rubber would make it even better. Six months later the original Bio-Fin Pro was introduced. It has been "Tester's Choice" every year since 1999.

The proven performance of the original PRO model moved industry leaders to embrace the idea of propeller fin technology. Inspired by "the best new diving product introduced in over a decade" Rodale's Scuba Diving, Feb 1999, others began to produce their own synthetic variations of the Bio-Fin.

Amongst some stiff competition the 100% rubber Bio-Fin Pro has been awarded "Best Overall" every year since 2001.

Frequently Asked Questions
Would a stiffer fin be more powerful?
A stiffer fin will give the feel of more power. However, this feeling can be deceptive. Divers have often commented that they cannot feel the fins when kicking and some have equated this with a lack of power. However, if they were diving with others that were not using all rubber split fins more often than not they found themselves far ahead of the pack. The same result has occurred time after time in fin tests. It has been proven that Bio-Fin divers are moving quicker while using less effort and less air!

We have also heard the comment that the PRO is not stiff enough to work well in current / surge. Again look back and see how much effort your buddy is making in comparison to you. If for some reason he is actually ahead then take a moment to consider how you are kicking. A stiffer fin or paddle type requires a wider kick to get moving. Divers that have used paddle fins or stiffer split fins in the past are conditioned to kick hard and wide when faced with current or surge. Subsequently, they are using much more effort and air to move which decreases comfort reduces time underwater.

The Bio-Fin requires much less effort. A small kick creates a propeller type effect; if your kick is too wide then you will lose the momentum and power the fin is designed to provide. The Bio-Fin series allows you to relax a little. Don't try so hard; it is no longer necessary. The series was designed with the optimum angle, weight, and stiffness. It requires less effort, less air consumption, and will in reality provide far more power and speed than the wide kick required with other fins.

Pro vs. Pro XT: which one is right for you?
The PRO and UNI Bio-Fins have an average* durometer (stiffness level) of 68. This durometer has been proven to provide the highest degree of comfort, speed, and forward thrust. The only drawbacks of this durometer level are that turn response is a bit lower, and alternative finning such as a frog kick does not respond as well.
*There is a very slight change in durometer within models due to color additives. However, the difference is so minimal that performance is not significantly affected.

We created a stiffer model, the Bio-Fin XT, to accommodate the diver that prefers to fin with a frog kick, requires the ability to stop and turn quicker, or simply prefers the "feel" of a stiffer blade.

The XT is also produced of 100% rubber. However, the durometer has been increased to 75; to provide a stiffer blade. We could have chosen a plastic or plastic rubber compound to build a fin with the same stiffness. In fact some of our discontinued models were produced in these alternative materials with this in mind. After extensive testing we found that rubber would maintain the highest level of comfort, speed, and performance that could be derived from a stiffer fin.

What about the other brand rubber split fins available?
While there are a few brands that are produced in a rubber / plastic compound; Apollo is the only manufacturer to use 100% rubber.
