Carbon fins, are they worth it???
« on: May 04, 2014, 10:06:12 AM »
This is only my second year diving, but I am now getting down past 30; negative buoyancy. I'm wondering if carbon fins make that big of a difference, to justify the price. Any and all input is welcome, thank.

Picasso "Black Team" and Omer "Sting Ray". Just picked up the Picasso's used and haven't really tried them out yet.

Carbon blades will be a lot more responsive than plastic blades, so they will perform much better when diving deeper.  Maybe not the best choice for shallow water, but I use them exclusively.  I have the Riffe plastic fins, which are probably similar to the teams, and I prefer the carbon even if they are twice the price.  But that's just my opinion.

This is probably why I don't find them a whole lot better.  :-X Haha

Lol.  One way to look at it is how many kick cycles it takes to get to depth.  For instance, a kick cycle is kicking once with each leg.  If you dive to 50 feet with plastic fins and it takes 9 kick cycles until you fall to the bottom and 16 kick cycles to get back to the surface, but the same dive in carbon fins takes 7 cycles until you're negative and 13 to regain the surface, the math shows the fins to be 20% more efficient.  That makes a huge difference diving to depth when you're doing a lot of kicking.

The same comparison in 25 FOW where it takes half of the effort to make the dive, the difference isn't that great. 

But that's just one way to look at it.

If you decide to go carbon, here's the link to abyss. They support our site and you can get a set of blades with foot pockets for around $300.

There are other benefits too; they are lighter.  More responsive blades allow for a less aggressive kick so you can use less energy while swimming under water.  I think they are faster.  Mine have an angle built in that makes for easier surface swimming.  They come in varying degrees of stiffness for those of us who may be diving very deep or for bigger/heavier guys.  All of which may increase bottom times.  Probably most important, they look way cool in the fish porn pics!

Thanks for all the input, perfect example of why this club is so great!!! I think I will start saving for a pair. I am currently diving at 30-33 feet, but hope to be able to comfortably dive 45-55 feet. Hopefully I will be able to test a few different pairs out over the next few months.
Joshua, I will check out http://www.abyss-diver.com/ .

I went from plastic fins to carbon,and my diving improved immediately.
My drops were Easy and my depth got at least 15'more for the same effort.
Leg strain and fatigue went away as well.
Well worth the money,but they are not cheep.about $450.
I agree that the biggest difference is below 20'and the kick cycle comments are right on.
Less kicks less air used.
I went with Blue tec flames.
My buds have: c4 ,diver R,mako,and spiero flames.
Chuck
Stay calm and dive on
