Apeks RK3 Open Heel Fins

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 four sizes: Small, Medium, Large and Super. 

Features:

- 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 is designed to hold up to the toughest environments, temperatures, and abuse.
- Two large grommet holes designed to fit most carabiners for easy storage of the fins while accessing the dive site.
- Spring straps as standard.
- Custom designed buckle holds spring straps in optimum position.
- Simple push pin design allows simple replacement of springs if necessary
