High quality hand crafted carbon fins from BlackTech.

Specifically designed for professional and experienced freedivers, diving to depths greater than 30 meters (100 feet) who prefer softer blades.

BlackTech Variable width blades are made using the latest laser technology from 100% high tensile carbon material for optimal performance during a vertical dive.

Featuring Variable height rails which reduce water turbulence, improve handling underwater and allow optimal stability, reactivity and energy efficiency.

The blades are produced by advanced VRTM (Vacuum Resin Transfer Moulding) technology using specially formulated Epoxy resins for marine use, ensuring zero crack propagation throughout the blades, extraordinary resilience and flexing properties and highly efficient fluid kick.

Supplied with a 3 years warranty for materials and craftsmanship.
