Model Number: SF-15

OVERVIEW

Over 5 years of research and development brought the highly regarded and best-selling SF-8 X-Pert Zoom split fin to market in 2003.  TUSA redefines the fin market again with the introduction of the SF-15 X-Pert Zoom Z3.  

The SF-15 further improves upon the performance, features and design of the SF-8 with the incorporation of 3 materials, 10% longer blade length, enhanced propeller-fin technology, reinforced blade rails and optimized blade scoops.  These new features along with TUSA's patented 27° Angled Blade Design and EZ strap buckle system make the SF-15 THE fin for divers.

TUSA's Angled Blade Design:

When using the standard traditional blade fin, with the leg completely extended, there remains an angle of 27° between the heel and the foot and the calf of the leg, causing a 10% loss of propulsion. Because the fin is angled below the body, during the kick phase, the body is pushed forward and down, instead of straight ahead.  With the SF-15 fin, that 27° angle has been designed into the fin.  This means that 100% of the energy expended during the kick phase is directed toward the propulsion of the diver.  To achieve maximum performance from this fin, use a small bent-knee kick with a light rhythm. This creates less strain on the leg muscles compared with traditional fins, reducing the diver's fatigue and subsequent air consumption.
