Efficiency and power
At Subea, we have developed a "fin robot". This robot is a test bench for measuring the fin's propulsion output and the energy required from the diver. From this we can deduce the efficiency of a fin.
We use this robot throughout the development of our products to correlate our sensations in use with a scientific measurement.
Each fin prototype is tested until we obtain the product that meets our expectations.
Slippers
The part of the fin where the foot is positioned.
The SCD 900 fin shoe has been specially designed to fit snugly over the foot. Its central "X" keeps the foot firmly planted in the fin, so there's no sensation of losing the fin during use.
The rear pull tab on the heel makes it easy to adjust the fin.
Canopy
The flat part of the fin contributes to its power.
The SCD 900 fin has a bi-material blade with two different hardnesses.
The use of a softer material on the three channels maximizes their deployment and increases thrust. Their "accordion" shape also increases the volume of water displaced and thus increases thrust.
The side ribs are sturdy and thick to transmit muscular power along the entire length of the fin.
Dimensions and weight of fins (size 42/43)
Length: 73 cm.
Width: 22.5 cm.
Weight: 2kg (pair).
stability
The lateral ribs, the fin position centred in the middle of these ribs, and the fins on the sides or tip and under the fin ensure excellent fin stability, whatever the finning technique (classic, scissor or frog-kick).
Sole
The entire area under the foot is ribbed and made of soft material to limit slipping on the point of the boats.
The size marking is made extra thick with soft material for easy reading.
