Apeks RK3 Military Rubber Fin with Adjustable Stainless Steel Spring Straps

For decades, the RK3 fin design has been the preferred choice of Military, Special Ops, Coast Guard, and Public Safety Divers. It is a traditional all rubber design known for its durability in the most challenging environments, extreme temperatures, and tough conditions.

The RK3 blade material is specially formulated to withstand these harsh conditions and abuse that divers often face. Its short and wide blade design allows for maximum forward thrust while still providing excellent maneuverability. Additionally, the vented blade design reduces resistance on the upstroke and enhances thrust on the downstroke, further improving performance.

What sets the RK3 fins apart is the inclusion of stainless steel spring straps as a standard feature. These straps make it easier to put on and take off the fins, especially when faced with cold hands or when wearing thick gloves.

Originally based on one of the first vented rubber fins sold in North America, the RK3 design has gained popularity among military and professional divers. Its compact size and ultra-rugged construction make it perfectly suited for use in harsh environments.

Overall, the RK3 fin design has proven to be the go-to choice for military, special ops, coast guard, and public safety divers for many years. Its combination of maximum thrust, maneuverability, and durability has made it the standard gear issued fin in these sectors.
