Apeks RK3 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 oversized foot pocket to accommodate dry-suit boots and a spring strap for easy donning and doffing. The RK3 is available in three sizes: Medium, Large and Super.

Apeks didn't give the RK3 fin a shoe size range, as this can be very misleading.

The environment in which an RK3 is used dictates the fin size you need. For example, do you dive in a warm environment wearing wetsuit boots, or are you walking across pebbled beaches and wearing a drysuit and rigid dry boots? Both forms of footwear may be a size nine but will take up different amounts of space in the fin foot pocket.

Apeks RK3 Fins Features

  • The RK3 is based on one of the first vented rubber fins sold in North America and is popular among military and professional divers.
  • Compact and ultra-rugged for use in harsh environments.
  • Improved foot pocket with spring straps for easy use with cold hands or thick gloves.
  • The design has been the standard gear issue fin for military, special ops, Coast Guard and public safety divers for decades.
  • A short, broad blade provides maximum forward thrust while maintaining excellent manoeuvrability.
  • The 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 like split fins eliminate the vortex.
  • The blade material is designed to withstand temperatures and abuse in demanding environments.
  • Two large grommet holes designed to fit most karabiners for easy storage of the fins while accessing the dive site.
  • Spring straps are standard.
  • The custom-designed buckle holds spring straps in the optimum position.
  • A simple push pin design allows for simply replacing springs if necessary.
