Apeks RK3 HD

Built for demanding diving conditions, the Apeks RK3 HD is a rugged, high-density thermoplastic rubber fin designed for divers who need stiffness, powerful propulsion, and excellent manoeuvrability.

Based on the iconic vented RK3 design, the RK3 HD features a stiffer blade and negative buoyancy, making it particularly suitable for wetsuit diving. Its compact, short, wide blade delivers powerful thrust while maintaining excellent control underwater.

The oversized foot pocket accommodates a variety of diving boots, including drysuit boots, while the standard stainless-steel spring straps make donning and doffing quick and easy, even when wearing thick gloves.

The durable construction is designed to withstand harsh environments, and the two large grommet holes allow the fins to be attached to suitable karabiners for convenient transport and storage.
