Freediving/ spearfishing fins

[Mateo Dalmato]

So the greatest thing ever ( innegra ) is nothing more than plastic and carbon . That's crazy for 800 $ price .. But if they are durable it can be worth it .

I hear all kinds of crazy stories that people willingly rub them to ocean floor and use them to jump from the floor and move etc on floor .

I mean , it's durable , but it's not of steel .

I have Mares Razor Pro and they are VERY durable , but they also can , as any fin , scrach and damage , bit by bit , and I do not want to accumulate damage .

But I buy Innegra I would take care of them even more than Mares Razor Pro which is cheap fin compared .

But there is no need for Innegra , when I have option of fiberglass and carbon/ fbg for cheap - performing better than Innegra .

Durability ? Relative thing ..carbon is the most durable in performance - but it's relative because it will probably damage . Plastics ? Lose performance sooner ? The worst ? In theory yes - but in real life they last so long that you extract more from them than from any other type of fin . And for 50-150 euro nothing can beat plastic and fiberglass .

that's what seller told me that new fins are coming without those ribs ..

it's making fins heavier and it's not adding performance ..

but still I think I didn't made mistake with Razor Pro , they are FAST and durable , and well made , even iron parts didn't rust , it's just so well made I am amazed .

not designed thou

without those ribs , and with more carbon etc would be better

I’ve been using the carbon leader fins now for 8 years, spearfishing. I abuse the **** out of them and have had no issues at all. Great blades, and especially considering the price.

I've had the older Leaderfins in the carbon/fiber composites for years and they were bullet proof. They came out with the short rib Forza foot pockets and I didn't like them it at all. I had a pair of Mako fiberglass fin that were amazing, my son talked me out of them, hahaha. I'm currently using Nautilus Phantom Carbons and they seem ok, they have Hammerhead foot pockets and they fit my wide feet perfect.

I think I would go to fiberglass now , from Mares Razor Pro .

I must choose online store etc to buy good fiberglass fins , in harder stiffness , with propet footpocket .

And there comes the problems , how to choose , sizing is different among brands etc ..

But I am okay with Mares Razor Pro so I do not hurry .

Revisiting this topic
Fiberglass fins are theoretically very close to carbon fins, IF made well. However most fiberglass fins aren't that well made. The manufacturing quality is good, but the fin mechanics not so much, I mean they are weaker or chuggier and the performance isn't as good as it could be. So realistically a carbon fin can give as much as 20-25% performance above a fiberglass fin (which is already much higher compared to plastic). To a significant extent this is because of the carbon's additional lightness on top of springiness

So unless fiberglass fins are significantly more economical than a pair of carbons, I'd go with carbons now that I've tried several pairs within a short timespan. For context, all pairs I tried were with short "nerves"/longerons on the footpocket so maybe that was the reason, and with traditional longer side nerves fiberglass can perform even closer to carbon
