Apeks RK3 Military Rubber Fin with Adjustable Stainless Steel Straps

The RK3 fin design has been the standard for Military, Special Ops, Coast Guard, and Public Safety Divers for decades. It is a traditional all rubber design, and the RK3 blade material is formulated to hold up in the toughest environments, temperatures, and abuse. The short wide blade provides maximum forward thrust while maintaining great maneuverability, and the vented blade design reduces resistance on the upstroke and enhances thrust on the downstroke. The fins come standard with stainless steel spring straps.

Based on one of the first vented rubber fins sold in North America, the RK3 fin design is popular among military and professional divers. Compact and ultra-rugged, it is designed for use in harsh environments. The improved foot pocket features spring straps for ease of use with cold hands or thick gloves.

For decades, the RK3 fin design has been the standard gear issue fin for military, special ops, coast guard, and public safety divers. Its short, wide blade provides maximum forward thrust while maintaining great maneuverability, making it a reliable and versatile choice for professionals operating in challenging conditions.
