SPORASUB SPITFIRE KELP FINS

2017 SEMI-TRANSPARENT NOVELTY

For 2017, Sporasub takes the field with some excellent new features including the new spitfire kelp fins. They have interchangeable polypropylene blades characterized by an eye-catching dark green colour and by the fact of being semi-transparent.

In addition blades also have a drop-shaped hole (10cm x 3.5cm) in proximity of the footpocket which actually is a drain valve allowing the leg to avoid fatigue during kicking while maintaining the expected high thrust properties.

The blade is well finished and has grains (4 above and 3 below) that strengthen it while keeping an excellent elastic responsiveness. The end tip is dovetail shaped with two small flaps (one on each side) that are 7cm in length and 1,3cm in height. The latter together with the drop-shaped hole help to avoid fin drifting during kicking.

Another very important aspect of the blade is that the polypropylene it is made of, is enriched with a substance that protects it against UV rays and the manufacturer also ensures that this material has an excellent performance at both low and a high temperatures, such property clearly guarantees a slow deterioration over time.

The footpocket is characterized by thermal rubber in two colors which represent two hardness types. To ensure the best comfort for the foot and to better support the spearo performance, the green thermal rubber (softer) is used for the top part of the heel and  the ankle contour, besides the tip of the foot, while the black thermal rubber, (harder), it is used for the bottom of the heel, the instep and the water rails.

The blades are 64 cm long from the bend under the footpocket to the tip while the width is 13.2 cm (measured between the water rails) and reaches the maximum value of 21.3 cm towards the tip. The full weight of the fin is slightly greater than one kilo.

It 'a product suitable for long surface displacements and ambushes at depths within  15mt.
