  • The design has been the standard gear issue fin for military, special ops, coast guard and public safety divers for decades.
  • Short wide blade provides maximum forward thrust while maintaining great manoeuvrability.
  • Vented blade design reduces resistance on the upstroke and enhances thrust on the downstroke.
  • The vents also eliminate vortexes that can occur along the back of the blade much in the same way split fins eliminate the vortex.
  • The blade material designed to hold up in the toughest environments, temperatures and abuse.
  • Two large grommet holes designed to fit most karabiners for easy storage of the fins while accessing the dive site.

Designed in collaboration with the US military and renowned for outstanding performance and reliability, the Apeks RK3 is a rugged thermoplastic rubber fin featuring an over-sized foot pocket to accommodate drysuit boots and a spring strap for easy donning and doffing. The RK3 is available in three sizes: Medium, Large and Super.


This new version of Apeks’ RK3 fin is made from a denser, negatively buoyant material. Like the original RK3, its DNA can be traced to some of the first vented-rubber scuba diving fins. Its tec orientation is clear, and to be fair, that put it at a disadvantage in our more rec-oriented evaluation. But despite that — and its stubby appearance (19 inches) — it notched performance scores at the top. Scuba divers rated it very good for power vs. stress, acceleration and manoeuvrability. Fittingly, given its froglike appearance, it took top score for efficiency in frog style. The flutter, especially at speed, was a little more work given the fin’s weight (2½ pounds each), but still rated very good. Though on the boxy side, the foot pockets provide good support, and the fin earned very good scores for comfort and stability.” – Review by www.scubadiving.com
