Fourth Element - Tech Fin
A classic vented fin, redesigned to maximize performance. Utilizing natural rubber in a unique density gradient, this fin delivers a comfortable foot pocket combined with optimized 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 maximize the return on effort.
The Tech Fins were developed with technical divers in mind with a slightly negative buoyancy characteristic but is suitable for all levels of diver looking for a high-performance rubber fin.
FEATURES:
- Natural rubber heel strap
- Stainless steel spring strap
- Soft foot pocket
- Hydro-flow vents
- Turbulence disruptors
- Strengthening ribs
- Stiffening lateral rails
