Apeks 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 oversized foot pocket to accommodate dry-suit boots and a spring strap for easy donning and doffing. The RK3 is available in three sizes: Medium, Large and Super.

Apeks didn't give the RK3 fin a shoe size range, as this can be very misleading.

The environment in which an RK3 is used dictates the fin size you need. For example, do you dive in a warm environment wearing wetsuit boots, or are you walking across pebbled beaches and wearing a drysuit and rigid dry boots? Both forms of footwear may be a size nine but will take up different amounts of space in the fin foot pocket.

Apeks RK3 Fins Features

The RK3 is based on one of the first vented rubber fins sold in North America and is popular among military and professional divers.
Compact and ultra-rugged for use in harsh environments.
Improved foot pocket with spring straps for easy 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.
A short, broad blade provides maximum forward thrust while maintaining excellent manoeuvrability.
The 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 like split fins eliminate the vortex.
The blade material is designed to withstand temperatures and abuse in demanding environments.
Two large grommet holes designed to fit most karabiners for easy storage of the fins while accessing the dive site.
Spring straps are standard.
The custom-designed buckle holds spring straps in the optimum position.
A simple push pin design allows for simply replacing springs if necessary.
