CETMA Composites PRANA Carbon Fin Blades - For CETMA S-Wing Footpockets

Love my fins! So glad they helped me fit them!

I chose these over the mantras or edges for a few specific readons. I typically spearfish the Northeast US, Long Island NY, and the diving we get around here has a lot of jetty entries and rocky structure underwater. These are slightly shorter than the other Cetma models, which is useful because in shallow, low viz, rocky areas, long fins have plenty of potential collisions, as opposed to using them in more open spaces like blue water and tropical deep reefs. And whereas other Cetmas are entirely carbon, these are ¼ fiberglass, which I figured would contribute a bit to their durability. Overall, these have proved great for the area. Despite being on the shorter end of Freediving bifins, I’ve had no issue in hunting 50-55’ deep during my occasional trips to block island (I’ve taken them as deep as 85’, but didn’t hunt at that depth). And, more notably, for shallow diving (12-30’) in rocky areas with strong currents, the reduced length reduces the chance you’ll accidentally kick a boulder you didn’t see.

Overall, while I’d consider buying a different fin if I was always diving bluewater or tropics, if I’m doing 50% or more of my diving in colder&shallower rocky areas, this is absolutely a great fin for that. Areas like the Northeast Coast of the US, any inshore diving on the west coast (lingcod, kelp forests, etc) or maybe even some of the low viz areas in the UK, these fins should be ones you consider.
