The Apeks RK3 is a rugged thermoplastic rubber fin with an oversized foot pocket for drysuit boots and a spring strap for easy donning and doffing. This listing is the black fin in size M.

Main features

• Based on one of the first vented rubber fins sold in North America, a design long issued to military, coast guard and public safety divers.
• Compact and very rugged, for harsh environments.
• Short, wide blade for strong forward thrust and good manoeuvrability.
• Vented blade that reduces resistance on the upstroke and adds thrust on the downstroke.
• Foot pocket sized for drysuit boots.
• Spring straps as standard, easy to use with cold hands or thick gloves; a push-pin design makes the springs simple to replace.
• Two large grommet holes that fit most karabiners, for carrying the fins to the dive site.

Good to know

Apeks gives no shoe-size range for the RK3, because the footwear you dive in decides the fit: a wetsuit boot and a rigid drysuit boot of the same shoe size take up different amounts of room in the foot pocket.
