Fourth Element’s has launched a new model of fin for technical divers. The ‘Tech Fin’ is a classic vented fin design, which Fourth Element says have ‘taken inspiration from nature and evolution to optimise efficiency.’
Turbulence disruptors on the top of the Tech Fins’ blades have been designed to 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, creating turbulence which enables the whale to swim more efficiently.
The fin is constructed from natural rubber in a unique density gradient, which Fourth Element claim 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, while 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 is designed to allow greater manoeuvrability without compromising the power, while the shorter length is aimed at improving agility and making stowing the fins for transport more convenient.
Spring straps with comfortable heel pads keep the feet securely held in place, and 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.
The Tech Fins are available in M, L, XL and XXL. These fins will fit sizes 4 (US5) to 14 (US15) and come in Black, Grey or Aqua.
