The Apeks RK3 HD fins are made from a higher density material than the standard RK3, which makes the fin stiffer and heavier. The new compound of the RK3 HD adds more weight to make it negatively buoyant.
Apeks RK3 HD fins are 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.
