The Apeks RK3 Fins are super hard wearing thermoplastic rubber fins designed in collaboration with military and public service divers for performance and reliability in the hardest conditions.
Solid Rubber Design has no joins or hinges to split or break. The compact vented design has been standard issue fin for military, special ops, coast guard and public safety divers for decades and is popular with professional divers around the world. Made for the most rugged environments the RK3 are great for technical divers for pure reliability and cave divers from their compact design and transportability.
Two Hanging Loops that make storage on pegs easy and transport with karabiners capable without having to customise the blade.
Vented Design improves efficiency by reducing the resistance on your ankle on the upstroke and enhances thrust on the downstroke by channelling water by eliminating vortices along the back of the blade.
Also Available in HD. The RK3 have two versions; standard and HD. Both the same shape and design, the RK3HD are a stiffer version that are more efficient but use more energy from your legs. If you want to fight currents or shift gear faster then the HD version will get you through the water faster but you do need strong legs to use them for long periods. For a more relaxed recreational dive the Standard version will be more comfortable. They will still get you where you need to go but you're legs won't ache as much.
The Standard and HD version look almost identical except for a small number 70 inside the foot pocket.

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. We didn't give the RK3 fin a shoe size range as this can be very misleading. 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. Based on one of the first vented rubber fins sold in North America and popular among military and professional divers. Compact, and ultra-rugged for use in harsh environments. Improved foot pocket with spring straps for ease of 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. 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. Spring straps as standard. Custom designed buckle holds spring straps in optimum position. Simple push pin design allows simple replacement of springs if necessary.
