The Apeks RK3 HD Fins are a stiffer version of the popular RK3 Fins. Tougher material improves the performance of the fins so you can move through the water faster and small kicks will have a greater effect. Modeled from the trusted Military Rocket Fins The RK3 were designed in collaboration with public service divers who need a tough and reliable fin to do their duty in the harshest conditions.


Solid Rubber Design has no joins or hinges to split or break. The compact vented design has been standard issue fin for military, special ops, coast guard and public safety divers for decades and is popular with professional divers around the world. Made for the most rugged environments the RK3 are great for technical divers for pure reliability and cave divers from their compact design and transportability.

Two Hanging Loops that make storage on pegs easy and transport with karabiners capable without having to customise the blade.

Vented Design improves efficiency by reducing the resistance on your ankle on the upstroke and enhances thrust on the downstroke by channelling water by eliminating vortices along the back of the blade.

Apeks RK3 HD Fins - Features

FeatureProduct Specification
Blade Type
?Advances in design, materials and manufacturing techniques has allowed the development of various differenet types of fin blades which control the movement of water in different ways.

More advanced blades, including split and hinged blades, can dramatically increase efficiency, helping to improve propulsion but also lower the amount of energy required to operate the fins.
Fin Length (mm)
?The overall fin length of a medium sized fin
Fin Weight (Pair kg)
?The overall weight of a pair of medium fins including buckles and straps
Foot Type
?Fins are available in two fitting types, open heel and full foot pocket.

Open Heel are typically used for scuba diving as they are able to provide better propulsion due to their increased strength and weight.

Full Foot Pocket fins are usually worn by snorkellers who produce significantly less drag when moving through the water compared to a scuba diver. As a result the fins are generally smaller and much lighter.
Open Heel
Quick Release Buckle
?Quick release buckles aid fitting and removal of the fins by allowing rapid fitting and release of the fin strap.

Rather than having to loosen the fin strap off before pulling it over your heel to remove the fin, the quick release buckle allows you to disconnect the strap and slide your foot straight out.
Strap Type
?A number of different fin strap styles can now by found on fins including the traditional adjustable rubber strap, metal spring straps and also bungee straps.

Rubber straps can be easily adjusted to suit each individual diver and are typically fitted with quick release buckles.

Spring and bungee straps are generally not adjustable and are sized to suit the fin size, however, they offer an extra level of comfort and flex better during the kick motion.

Excellent fins

These fins are excellent. It very simple to don them on and off, they feel really secured and are very comfortable. One point to keep in mind for the trim conscious ones out there is that they are on the heavy side and "slightly" negatively buoyant, so they might be better suited to people diving with a dry suit. If not, the non HD model should take care of that.

De très bonnes palmes

Après avoir lu des tas d’articles et d’avis positifs sur ces RK3 HD, je m’étais décidé à les acheter.

Franchement, leur épuration n’est pas usurpée : elles sont déjà très bien dessinées et la qualité du plastique est perceptible au toucher, on sent déjà une très nette différence avec certaines palmes de qualité et d’un certain prix ...

Ensuite, une fois sous l’eau, on sent clairement la différence avec avant, la poussée est plus forte, plus nette, plus tranchante.

Sinon, elle sont très confortables aussi.

I use the fins with a dry suit and they are very small fitting. My dry suit boots are a 6 but I need a large size fin. Very easy to use fins when in water and relatively easy to pull springs to remove and put on.

These fins are like the Scubapro jet fins (amazing btw) but they have better and more comfortable features like the bigger foot pocket, the karabiner holes, the better spring strap, the drainage holes in the foot pocket, and the fact that it is small
