Great Fins for both recreational and tech diving. Can be used with both dry suit and wet suit boots.

Great colour and in excellent working condition. Been worn so a few marks on them.

The adjustable strap allows it to fit a lot of sizes. I am size 9 and fits great and can fit far larger with the extended strap.

Feel free to ask questions or request any further photos.

DESCRIPTION

The Apeks RK3 HD Fins are made from a higher density material than the standard RK3, which makes the fin stiffer and negatively buoyant, ideal for drysuit diving.

The RK3 HD fins are based on one of the first vented rubber fins sold in North America and popular among military and professional divers. The design has been the standard gear issue fin for military, special ops, coast guard, and public safety divers for decades.

Features of Apeks RK3 HD Fins

Short wide blade provides maximum forward thrust while maintaining great manoeuvrability.

The blade material is designed to hold up to the toughest environments, temperatures, and abuse.

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.

Two large grommet holes designed to fit most carabiners 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.

Fin sizing

Apeks didn’t give the RK3 HD fin a shoe size range as this can be very misleading. The environment that an RK3 HD is used in will tend to dictate the size of the fin that 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 UK size 9 but will take up different amounts of space in the fin foot pocket.
