SUBEA SCD 100 scuba diving fins blue/neon yellow

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.

The part of the fin where the foot is placed. It can be completely closed, like in full-foot fins, or open with an adjustable strap, like in adjustable fins.

The flat part of the fin that helps to generate the thrust. The longer and/or harder the blade, the more powerful the fin. The shorter and/or softer the blade, the less powerful the fin.
