Twin Speeds

By closely observing nature, our engineers have designed this exceptional fin. It is a revolutionary concept that exceeds today's traditional fin performance by 30%, while reducing diver effort. Revolutionary new look and feel: a true blend of style and performance. Works like counter-rotating propellers to reduce drag and turbulence. Achieves 30% more efficiency than conventional fins.

* Semi-rigid yet elastic spine

Creates a supporting framework for other components.

* Soft, pre-shaped webbing sections

Channels the water efficiently to create maximum forward thrust with less wasted downdraft. Reduces effort required for power stroke.

* Elastic semi-rigid side ribs

Increased elasticity, which helps the return of the blade. More power, less effort.

* Soft, semi-rigid, closed-toe foot pocket

For optimum leverage and exceptional comfort for extended dives.

* Patented tri-compound construction

Optimum use of 3 different materials achieves superior performance

“My favorite fin, whether with my short boots while snorkeling or with a full boot working against a current, I find I have less calf and hamstring fatigue and need to stretch much less often due to the power and ease of the Twin Speeds” Ian Barclay NAUI Diver
