Technical information

Performance and power

At Subea, we developed a "fin robot". This robot is a test bench that measures what the fin renders in terms of propulsion, thus what it requires in terms of energy from the diver. We can therefore deduce the efficiency of a fin.
We use this robot throughout our product development to correlate our feedback in use to a scientific measurement.
Each fin prototype 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 of the SCD 900 has been specially developed to hug the shape of the foot. The central X holds the foot firmly in place in the fin to stop the fin from feeling like it is falling off during use.
The rear tab at the heel lets you easily adjust the fin.


The flat part of the fin that helps to generate the thrust.
The blade of the SCD 900 fin is dual-material with two different levels of hardness.
The use of a softer material on the three channels maximises their expansion and increases thrust. Their “accordion” shape also increases the volume of water displaced and therefore increases thrust.
The side ridges are robust and thick to transfer muscle strength to the entirety of the length of the blade.

Dimensions and weight of a pair of fins (size EU 42/43)

Length: 73 cm.
Width: 22.5 cm.
Weight: 2 kg (per pair).


The side ribs, the position of the blade centred between these ribs and the side wings at the bottom and tip of the blade ensure very good stability of the fin, regardless of the kicking style (regular, scissor kick or using the frog-kick technique).


The entire area under the foot is grooved and made of a soft material to limit sliding on the deck of a boat.
The sizing is done in over-thickness with a soft material to be better understood.
