The Apeks RK3 HD Fins are a stiffer version of the popular RK3 Fins. Tougher material improves the performance of the fins so you can move through the water faster and small kicks will have a greater effect. Modeled from the trusted Military Rocket Fins The RK3 were designed in collaboration with public service divers who need a tough and reliable fin to do their duty in the harshest 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 Standard. 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.

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 weight to make it more negatively buoyant than the standard RK3. An ideal fin for dry suit diving. 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.
