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 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 maneuverability.
  
• Vented blade design reduces resistance on the upstroke and enhances thrust on the downstroke.
