Jet Fins Open Heel Fourth Element Tech

Jet Fins Open Heel Fourth Element Tech

Fourth Element’s new Tech Fins have taken inspiration from nature and evolution to optimise efficiency. The turbulence disruptors on the top of the blade work in the same way as the nodules of the leading edge of a humpback whale fin, which disrupt the water as they move through it. The resulting turbulence enables the whale to swim with more efficiency. Fourth Element has adopted this evolutionary concept to improve the performance of this classic fin.

Utilising natural rubber in a unique density gradient, the dive fin delivers an ultra- comfortable foot pocket combined with optimised stiffness for finning performance. The vented design allows water to flow along the blade reducing drag and fatigue, whilst the stiffening rails and ribs ensure that the blade of the fin is driven through the water to maximise the return on effort.

The Tech Fins, with a slightly negative buoyancy characteristic, were developed with technical divers in mind but are suitable for all levels of diver looking for a high-performance rubber fin. The wider blade gives manoeuvrability without compromising the power, while the shorter length improves agility and makes stowing the fins for transport more convenient. Spring straps with comfortable heel pads keep the feet securely held in place. These straps can be removed and changed easily with everyday tools if required.

The Tech Fins are supplied with a hanging/carrying strap and a marine quality bolt snap which may be used to attach them to a bcd or harness for carrying, leaving both hands free for climbing ladders or carrying other gear. The natural rubber material of this fin is extremely durable, and all components are recyclable at end of life.
