Apeks RK3 Military Rubber Fin with Adjustable Spring Straps

The RK3 fin design has long been the standard choice for Military, Special Ops, Coast Guard, and Public Safety Divers. It is a traditional all rubber design, with the blade material formulated to withstand the toughest environments, temperatures, and abuse. The short wide blade offers optimal forward thrust while still allowing for excellent maneuverability. Additionally, the vented blade design decreases resistance on the upstroke and enhances thrust on the downstroke. The fins also come equipped with stainless steel spring straps.

Originally one of the first vented rubber fins sold in North America, the RK3 design has remained popular among military and professional divers. It is compact, ultra-rugged, and ideal for use in harsh environments. The improved foot pocket accompanied by spring straps allows for ease of use, even with cold hands or thick gloves. As a result, this design has been the standard issue fin for military, special ops, coast guard, and public safety divers for many years. Its short wide blade continues to provide maximum forward thrust while maintaining great maneuverability.
