Decathlon | SCD 500 SCUBA Diving Fins Black/Blue

These fins offer a bi-material blade which creates a "spoon" effect, withgreat guiding for the fin under the water, promoting supple finning. Itsergonomic shoes are comfortable **Key benefits:** * Power: 3 * Power: Side ribs of variable thickness. Bi-material blade with flexible channel * Easy to move: SOFT Comfortable and fluid finning * Compact design: 3 * Compact design: Fin length in 42/43 = 66 cm * Stability: Side wings for stability regardless of the kicking technique.**Technical information:**Performance and power: At Subea, we developed a "fin robot". This robot is atest bench that measures what the fin renders in terms of propulsion, thuswhat it requires in terms of energy from the diver. We can therefore deducethe efficiency of a fin. We use this robot throughout our product developmentto correlate our feedback in use to a scientific measurement. Each finprototype is tested until we obtain the product that meets our expectations. ;Foot pocket: The part of the fin where the foot is placed. The foot pocket ofthe SCD 500 fin was specially developed to hug the shape of the foot and tokeep the fin firmly in place on the foot. This means that you will never havethe feeling of "losing" your fin and it enables maximum energy transfer to theblade of the fin. ; Blade: The flat part of the fin that helps to generate thethrust. The blade of the SCD 500 is amazingly flexible while providingoutstanding power under all conditions. SUBEA has developed this blade toprovide maximum thrust (fin power) while retaining a soft blade to providemaximum finning comfort. Its central channel flexes to maximise thrust. Try itand you won't go back. ; Dimensions and weight of a pair of fins (size EU42/43): Length: 66 cm. Width: 22.5 cm. Weight: 1.4 kg (per pair). Positivebuoyancy (it floats lightly) ; stability: The side ribs, the position of theblade centred between these ribs and the wings at the side and tip of theblade ensure very good stability of the fin, regardless of kicking technique(regular scissor kick or frog kick).
