tusa xpert zoom fins : 6 results priced between £25.00 and £150.00

Without a pair to hand to make a direct comparison, I was hard-pressed to see the difference between these fins and their forerunner, also still available. Perhaps it is the technopolymer mix that is different. They have the same split blade, augmented by stiff side supporting bars that dip away from the line of the foot-pocket at around 30°.

When using the standard traditional blade fin, with the leg completely extended, there remains an angle of 27 degrees 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 degree angle has been designed into the fin. This means that 100% of the energy expended during the kick phase is directed toward the propulsion...

Unlike traditional fins which create propulsion only through repulsive force, the SF-8 attains propulsion by creating a pressure differential in the water flow. 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. The SF-8 Xpert Zoom fin's eye-catching design is causing quite a stir in the diving world! TUSA's production...

This unique fin features Propeller-fin technology which delivers the ultimate in performance and comfort. The water is propelled backwards instead of up and down and provides more power and less effort. Reduced fatigue, decreased air consumption and more speed are just a few of this fin?s great features. The angled design offers maximum kick effeciency and gives you longer time in the water.
