Apek's RK3 HD fins
The Apeks RK3 HD fin is the new professional solid rubber fin from Apeks, an upgrade of the popular Apeks RK3 rubber fin, a very high performance Apeks fin for technical diving and professional divers. The RK3 HD fins are test-winning open heel fins that outperform the Apeks RK3 heel strap fins in performance and material resilience, and were developed and tested in conjunction with the US military and experienced technical divers to meet the highest standards.
Manufactured to withstand the toughest diving conditions
Military divers, rescue divers and divers from special operations forces, coast guards and security organizations have sworn by this fin design for decades as these fins were developed to perform in the harshest environments. Therefore, the Apeks RK3 HD fins are not really suitable as entry-level fins or fins for divers who like to take it easy and relaxed, but are fins that "accelerate", fins with which you still have good propulsion even in strong currents or surf, hard fins that strain your leg muscles and get you moving forward in every situation, even at great depths and with extensive equipment.
The Apeks RK3 HD fins are made of durable thermoplastic rubber with a perfect balance between elasticity and thrust, a material that was also chosen because it is absolutely impervious to salt water, extreme temperatures and mechanical stress. Compared to the RK3 fins, the material of the RK3 HD solid rubber fins has a higher density, which means that the RK3 HD fins are even harder and heavier. This makes the RK3 HD fins the perfect fins for dry suits, as they have negative buoyancy, which is particularly beneficial for dry suit divers.
All other components of the RK3 HD fins are also trimmed for maximum durability, from the unbreakable buckles made of special plastic to the tear-resistant and rust-proof stainless steel spring straps.
Perfect thrust in all conditions
The short and wide shape of the blade of the Apeks RK3 HD fins ensures maximum propulsion and excellent maneuverability. The blade of the Apeks RK3 HD fins features flow slots that reduce resistance in the upward movement and increase the thrust of the downward movement while preventing the occurrence of turbulence and ensuring a smooth and even water flow along the fin.
Perfect fit and easy operation with any dive gear
The foot pocket of the Apeks RK3 HD fins has been cut extra wide because the fins are often used in extreme conditions where divers have to wear drysuits or heavy-duty neoprene boots. But the fin straps of the Apeks RK3 HD fins, consisting of robust stainless steel springs, ensure that the fins adapt to any type of boot and always provide a good fit. In addition, the RK3 HD fins are very easy to don and doff, even with thick neoprene gloves, thanks to these high-end steel straps with partial rubber coating.
For easy transport to and from the dive site, the RK3 HD rubber fins can be attached to the equipment with a suitable fin bracket or carabiner, as the fins are equipped with special transport eyelets.
