Apeks Tek RK3

Product description Apeks Tek RK3

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 RK3 is available in three sizes: Medium, Large and Super.


Based on one of the first vented rubber fins sold in North America and popular among military and professional divers.
Compact, and ultra-rugged for use in harsh environments.
Improved foot pocket with spring straps for ease of 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.
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 karabiners 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.

Very good fins


Good fins, I recommend.

Really good fins for the light setup


Just buoyant, good power for single tank wetsuit setup. Easy maneuvering in tight spaces I use HD version for twin set and drysuit, slightly heavier (negative buoyancy) and stiffer = more thrust

The best choices ... and the best of the price

After dozens of fins, these were the perfect ones, the relationship impulse effort is goodness, weight and size to store ideal, the best of them are indestrictible and of neutral flotability pulling a bit of positive. the momentum is so good that I even recommend them to dive in currents.
