A classic vented dive fin, engineered by nature and redesigned to maximise performance.

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.

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.

Technology

3D SYNQ: TUSA has developed a unique Fitting Ring that has been built into the Mask Skirt. This technology enables the Mask Skirt to mold to all face shapes providing the ideal fit, seal and underwater experience.

SWIFT BUCKLE 3D: TUSA has designed the perfect buckle and mask strap. The NEW low profile buckle is slim and light weight. The easy adjustment buckle and strap is silent and effortless when making adjustments.

FREEDOM TECHNOLOGY: Freedom Technology is a set of technologies to enhance fit and performance exclusive to TUSA. Freedom model masks feature a dimpled skirt surface with varied silicone thicknesses and stability ridges in addition to a proprietary low-friction skirt surface on the fitting line.

3D MASK STRAP: TUSA’s patented 3D Strap is a true three-dimensional design that snugly fits against the head’s natural curvature. The 3D strap offers unprecedented comfort and fit, unlike standard flat mask straps.

PANORAMIC VIEW: Panoramic View masks feature a variety of designs offering an incredibly wide field-of-view. Several designs incorporate minimum frame volumes, domed side-windows, reduced frame structures as well as three and four window styles for maximum vision.

ROUND EDGE SKIRT: TUSA’s Round Edge Skirt features a proprietary round edge cross-sectionally shaped skirt. This rounded edge results in a soft fit that suppresses pressure and reduces creasing left on the face. The “planar fit, instead of linear fit” silicone skirt maintains great fit and unprecedented comfort.
