Nautilus NS carbon fins AKA Leader fins

I have never tried Speardiver, but I have tried the Leaderfins. My lasting impression of the Leaderfins is that they were very heavy and I do a lot of shore diving and ended up selling them.

They are waching you.... :rolleyes1:

Leaderfins Carbon Price Update - Spearboard Spearfishing Community

Several months ago, I was at Nautilus and asked Andrew about the difference between the NS blades and the leaderfin blades. He told me that the NS series are made by leaderfins, but they have a higher ratio of carbon fiber to resin than the leaderfin carbons. Something like 15% if I remember right.

hmm interesting^^.... want to hear more on this

you can try out my c90's next time we go out.

I keep hearing that about Leaderfins that I think was an error in translation that keeps getting thrown around. The Carbon and Fiberglass are both "fibers". The epoxy used to wet it out is the "resin".

If they had to adjust the amount of "resin" they're using by 15%, their quality control issues are way beyond anything Dan has alluded to. :@

too late... i think im ganna head up to Dan 2morro if he is around and just buy the damn things.

What model do u have Ronny? i remember yours looking different than Brian's C90's.

After speaking with Andrew, this is in fact what I was trying to say. Leaderfin carbons have a 50/50 ratio of carbon fiber to fiberglass, whereas the NS blades are 60/40, making it 10% difference as opposed to the 15% I originally mentioned. My understanding is this production option is not currently available, but will be again in the future. IMO, since there is a difference in the two blades, a change in price is justified.. whether the increase in performance that comes from that extra 10% is worth $25 is up to the customer.

I think what your trying to relay is a higher percentage of carbon fiber to fiberglass. The Leaderfins are made up of a couple layers of fiberglass sandwiched between two (or more) pieces of carbon fiber. Varying the fiber to resin ratio will also adjust the properties of the composite but in a different way than changing the type of fiber. If the NS blades actually have a higher percentage of carbon then they should provide better performance than the "regular" Leaderfins. It would also be justification for a price difference.

The fiber to resin ratio is more a result of the manufacturing technique than anything. Hand laid composites will have a slightly higher ratio of resin to fiber than a vacuum layup. Generally you want less resin and more fiber.

you just have to believe in it.

Holy Prepreg.....you see the light

Need I need to say it? BS.

I then pledge to any one person with NS blades, to come come to me and I'll exchange the NS blades for Pursuit carbon blades. Then break the NS blades and show you exactly how much carbon is in there.

Does this mean i should go buy some NS blades before stopping by to save me some $????

im jk...

Yeah to type with more than 3 fingers

I used to believe this for the most part as well. I had a rich friend send me a pair of C4 Mustang 3-40's
that I wore a few times. I loved looking at them in the Dive Den....thought they might be a chick magnet.:laughing:.....but after getting Dan's C-90 meds and hammering the Shite out of them on shore dives and deep water at the Butterfly Bank they were sold to fund a vintage speargun.

Your welcome to take my Speardiver fins for a spin before the Mud craw begins.;)

Thanks for your help with the training, I already lost 5 lbs.

Cheers, Don

That sounds like a plan to me.
Nice job on the -5 too.
