ProteusCarbon fins are very fast, aggressive and one of the lightest fins on the market. We have specialized in creating the best option for spearfishing, in depth freediving competition and for free swimming. 

With the flexibility and reliability of ProteusCarbon blades, they allow you longer apnea, sleek and effortless movement both on and below the surface. They provide you energy saving movement, due to extreme responsiveness of special carbon and other high end material. This is the result of several year studies and applied research in the field of hydromechanics and research of technical materials.



Our journey into breath-hold spearfishing has begun in year 1998. At that time only plastic fins were accessible. We had the feeling, that someting is missing, that they are not good enough. We became eagerly desirous of achieving or obtaining something that is different and much better. We were searching for appropriate material, superior than plastic. We found the best solution in carbon fibres. This is how the engineering of invention began. 

We created the first carbon fins in 2003.

Through all these years we were constantly improving our carbon fins in cooperation with world class free divers, spearfishermans and other various people from scientist to ordinary divers. We were even producing blades for other world known brands under name ProteusCarbon. With them we achieved great success together and a lot of world and national records.

Now we have decided to step away and to offer the blades under our own brand.

We call them ProteusCarbon fins. 



Due to optimal blades curve and very fast responsiveness the energy of a stroke is transferred to the fin extremely fast, creating a strong accelerated thrust of water towards the tip of the fin. This is especially beneficial in ascent from depths when saving energy is of crucial importance.

The bottom part of the fin is sharkskin. This means you get optimal flow of water on this bottom part of the fin and at the same time the movement on the surface is silent. With matt surface you do not scare fishes underwater.  

All this can be achieved with best autoclave production technology and waterjet cutting technology.

This give us the privilege to create every fin:

- world class

- bubble free and

- exactly the same. 

Every blade is inspected with microscope, so we can provide you almost bubble free and only superior fins.
