Fourth Element Tech Fins | High-Performance Natural Rubber Diving Fins

Maximum Propulsion. Minimum Fatigue.

The Fourth Element Tech Fins are a classic vented fin, completely redesigned for performance. Built from natural rubber in a unique density gradient, they deliver a comfortable foot pocket with optimised blade stiffness — giving you powerful, efficient propulsion whether you're technical diving, recreational diving, or freediving.

Why Divers Choose the Tech Fins

• Vented blade design — reduces drag and fatigue by allowing water to flow along the blade
• Stiffening rails and ribs — maximise thrust and energy return on every kick
• Wider, shorter blade — excellent manoeuvrability without sacrificing power; easier to stow for travel
• Slightly negative buoyancy — ideal for technical divers; suitable for all levels
• Soft natural rubber foot pocket — comfortable for extended dives
• Stainless steel spring straps with comfortable heel pads — removable with everyday tools
• Hanging/carrying strap included — attach to BCD or harness, keeping both hands free
• Fully recyclable — all components recyclable at end of life

Limited Edition: Military Grade Green

The Green colourway is a limited edition military-grade fin with no metal parts and a double bungee cord replacing the traditional spring strap — ideal for environments where metal components are a concern.
