The Apeks RK3 HD fin is the latest in the RK3 range. It is made from a higher-density material than the standard RK3, which makes the fin stiffer and heavier and is therefore the ideal fin for drysuit diving. The new compound of the RK3 HD adds more weight to make it negatively buoyant.
Compact, and ultra-rugged for use in harsh environments, the Apeks RK3 HD features an improved foot pocket with spring straps for ease of use with cold hands or thick gloves. The short, wide blade provides maximum forward thrust while maintaining great manoeuvrability, and the vented blade design reduces resistance on the upstroke and enhances thrust on the downstroke.
