Aqua Lung RK3 Fins

Designed in collaboration with the US military and renowned for outstanding performance and reliability, the Apeks RK3 is a rugged thermoplastic rubber fin featuring an over-sized foot pocket to accommodate drysuit boots and a spring strap for easy donning and doffing. The design has been the standard gear issue fin for military, special ops, coast guard and public safety divers for decades. Traditional all rubber design. Short wide blade provides maximum forward thrust while maintaining great manoeuvrability. Vented blade design reduces resistance on the upstroke and enhances thrust on the downstroke. The vents also eliminate vortexes that can occur along the back of the blade much in the same way split fins eliminate the vortex. The blade material designed to hold up in the toughest environments, temperatures, and abuse. Two large grommet holes designed to fit most karabiner for easy storage of the fins while accessing the dive site. Spring straps as standard. Custom designed buckle holds spring straps in optimum position. Simple push pin design allows simple replacement of springs if necessary
