Apeks RK3 HD Fins Grey

Apeks RK3 HD Fins

The RK3 HD is the next fin in the RK3 range of fins. The RK3 HD is made from a higher density material than the standard RK3, which makes the fin stiffer and heavier. The RK3 HD was developed in response to feedback from divers who prefer a heavier fin. The new compound of the RK3 HD adds more weight to make it negatively buoyant.

An ideal fin for dry suit diving.

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.

The environment that an RK3 is used in will tend to dictate the size of fin that 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 9, but will take up different amounts of space in the fin foot pocket.

• The short wide blade provides maximum forward thrust while maintaining great maneuverability.
• 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 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.
• Stainless spring straps as standard.
• Custom designed buckle holds spring straps in optimum position.
• Same screw system as the Rocket.
• Simple push pin design allows simple replacement of springs if necessary.
