These are highly suitable for users who prefer a hard fin and who frequently dive up to 30 m (98 ft) within varying open water locations and also for those who whilst diving against strong natural currents require a bit of extra thrust.

A revolutionary new design and structure of fin with variable blades, harder around the foot at the top and softer at the end towards the tip. Our ultimate carbon layer positioning inside each blade created using the latest LASER technology ensures that every blades is almost identical. The power and feedback from each kick allows for continuous fluid movement without any dead spots even during vertical assent; they offer the ultimate feedback of nerve and speed.

Fibres: 100% high-tensile carbon
Resin: specially formulated epoxy resin used in marine and general industrial composite areas. All systems are Germanischer Lloyd approved.

BLACKTECH water rails with variable height and high efficiency designed to decrease all the turbulence in bending phase made of special rubber highly resistant to abrasion and which allows blades’ high reactivity and efficiency. They allow higher stability and better handling underwater. These water rails come in a recognizable blue color.

Blade tips are shaped to give the maximum amount of thrust with the smallest amount of energy consumption.

Much attention has been paid even to the smallest details in the aesthetics of BLACKTECH fins and blades, including their high-end finish. The extraordinary mirror surfaces of our blades both front and back is BLACKTECH’s unique difference. Waterrails are blue. Modern and attractive designs are used throughout. We offer everything you need to fall in love with your fins.

Advanced VRTM (Vacuum Resin Transfer Moulding) technology is used in the production of BLACKTECH carbon fibres blades, high temperature and high degree of applied vacuum, which lead to a component with 0% void level, without defects, with a uniform matrix/reinforcement ratio across the whole blade. Constant ambient temperature and humidity is used in compliance with the most demanding and modern standards. The blades are subjected under 14 hours post curing process in temperatures controlled through PLC (Programmable Logic Controller) with a deviation of less than ± 0,1°C in the chamber.

3 years of written warranty on breaking.
