Completely clear without imperfections, specifically designed for spearfishing in shallow water - where excellent camuflage is essential and ideal for freediving to depths of up to 30 m / 100 feet.

BlackTech Variable width blades are made using the latest laser technology from high tensile fiberglass material for reduced noise during fining.

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