  • Ergonomic Design

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

  • 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 blade directs water flow over the leading and trailing edges to provide power, lift and forward thrust on each stroke.


    Efficient Kicking  A wider kick results in loss of momentum. Whether your traveling at cruise speed or powering through current keep your kicks small.   You will move quicker and more efficiently.

  • Strap Type | Rubber or Spring

    • Rubber Strap is most common choice for military.  Strap adjusts in seconds to suit a wide variety of footwear and users.  Press clip to adjust length.  Quick release buckle.
    • Spring Strap is extremely durable and easiest to don and doff. Fins sold with specific length of spring. Additional spring lengths available.  T20 driver is required to change spring.  Auto adjusts to remain snug throughout dive.
  • Material

    Operators prefer to use the Bio Fin Pro series because the 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.
