Bio Fin Pro Series

 

Brand does matter!  Apollo Bio Fins are only split fins made from 100% natural rubber material.  The Bio Fin has proven to be a superior design for short and long distance water operations.  Its capability covers all aspects of military operations such as MCT (Maritime Counter Terrorism), MTO (Maritime Tactical Operations), MCM (Mine Counter Measures) and UBDR (Underwater Battle Damage Repair).

 

Operators prefer to use the Bio Fin Pro series because the natural rubber is negatively buoyant.  The flexibility of rubber increases thrust and reduces the risk of surface splashing.  If the operator is required to discard the fin, it will sink to the bottom so as not to alert the target of operators presence.  The design of the fin make it ideal for helicopter drops.

 

Independently voted the best overall fin in the world by Scuba Diving Magazine and the first choice of many Military Special Forces units worldwide.

Paddle Fins = Power on down stroke only

Bio Fins = Power on up and down stroke

Split Fin Technology Bio Fins provide lift and propulsion with less effort and more power.  Unlike other fins which push water up and down, Bio Fin blades direct water flow over the leading and trailing edges to provide power, lift and forward thrust on each stroke.  Apollo launched the original split fin in 1998.  Over 15 years of rave reviews and awards, no other fin has beaten the consistently high scores awarded by Scuba Lab and Scuba Gear Reports.

100% Natural Rubber - Only From Apollo Superior to any synthetic or hybrid material, Bio Fins are the only split fins made with 100% natural rubber.  Rubber can be a bit heavier to tote around in a dive bag than the plastics used for most fins but the comfort, flexibility and responsiveness while diving can't be beat.  Materials in design won Apollo Bio Fins over 9 awards since 1998 and is still used by testers as the fin to beat.

Ergonomic Design Apollo Bio Fins are designed with a 20º angle to accommodate a diver's natural tendency to bend slightly at the ankle and knee.  The angle is crucial to top performance and comfort.  The result is maximum propulsion with the least amount of stress on the body.  Apollo's choice of superior material and intelligent design provide divers with quick acceleration and the ultimate in power, speed and control.

 

Kicking It Wider kicks result in loss of momentum. Whether your cruising along or powering through current keep your kicks small.

Size chart is intended as a guideline. Actual fit may vary.  Recommendation is based on use of 5 mm boot with average sole.  If you are in between sizes and have a wider foot or thicker soled boot we recommend selecting the larger size.   *Weight and dimensions approximate based on black fins with rubber strap.

 

Customize Fit:  C-series fins are stocked and offered with a specific spring strap length. For example, size L is offered with a 300 mm spring.  If you prefer a more customized fit, springs are available to purchase separately in 250 - 350 mm.  See Fin Accessories and Spares for more info.
