  • Alternative connection of shooting line to spear

    I think it's interesting the mechanics of how it would work, never mind that it's impractical in most situations. I wouldn't have thought of making an "articulated shaft" myself, probably because it's never been necessary, but it surprised me. I wonder if Marco is surprised that omer chose to market such a thing :)


    Along the same line of thought I'd like to see very clear footage of what a shooting line does when a shaft is released from the mech. Although whatever happens is good enough, I don't know that there's that much of a difference in terms of range and accuacy between freeshafting and using a shooting line. Or wait maybe that's why all those scuba freeshafters are such badasses <img src= " height="23" srcset="https://spearfishing.world/forum/images/smilies/emojione/1f606@2x.png 2x">

  • Adjusting footpockets

    I'm very glad to hear it Kleberson. Looking at the pic could you please tell me the numbers where you felt the pocket was too tight and is now good?


  • Footpocket weight and sizing

    My digital postage scale is probably not that accurate.

  • Fin specs; stiffness, length, weight and flex points

    C4 Fuego VGR (Variable Geometry Rails) - Mega force T700 %100 carbon, D.P.C. (Double Parabolic Curve)


    Blade length: 81cm
    Fin length (blade + footpocket): 86cm
    Blade width: 18.5cm
    Blade width with rails: 19cm
    Angle at f/p: 15°
    Blade weight with rails: 350g
    Fin weight: 1010g


    Flex point: There's one pronounced flex point at 53cm from the back end. This is the blade on it's own without the f/p stiffening it up, and with the f/p since the C4 footpocket offers no practical support for the rear portion of the blade.
    Stiffness: Overall this blade handles very soft, softer than a Pursuit MS (Medium Soft), actually it's like a noodle. But I think this is due to the pronounced flex point since the blade area from the back to the FP is fairly stiff, and so is the area from the FP to the front, equivalent to about a Pursuit M (medium).


    When I flex the blade in this manner I'm only putting pressure in one direction, down. So the flex you see is where the blade prefers to bend on it's own. BTW notice the shape the rails are assuming, doesn't look efficient for water channeling. The rails are overly robust and feel like they're slowing down the blade.



    I prefer a more gradual/evenly distributed over the length of the blade flex. I haven't tried the C4 Fuego fins in the water but I do know with certainty that such a pronounced flex point will allow the blade to be more easily overpowered, and at such point make it a soft fin that lacks in propulsion, at the same time creating a weak/stress point where the blade is likely to fail.


    Miscellaneous pic of me shaping a Pursuit blade to fit the C4 footpocket.


  • Blond Russian Spearfishing in Black Bikini

    Thanks Don.


    What I enjoy most about this movie is Jean Reno's performance, he's really perfect for this role. Also the actor they had portray him as a kid. The B&W childhood Mediterranean diving scenes are also nice/nostalgic. I did watch the movie again last night and like the first time I saw it find the Jacques Mayol character to be too far fetched for my taste. I mean I can dig idealism but I keep my mind focused on the fact that the sea is not an environment suitable for men, and that I can enjoy it only temporarily. I don't think I'll be watching the Big blue again. If someone wants the DVD shoot me a pm and I'll mail it to you.

  • Intro

    Nice intro Austin. Welcome to the forum. Thank's for sharing the vid, I thought it was very good. It showed me a new angle on what hunting in the kelp is like, something I've never experienced.

  • Hello...

    Welcome to the forum Dave.


    Apart from the satisfaction of making your gear I believe you will find making fins to not be worth it. You will have many failed tries before you figure out the way to get the stiffness and flex you want. Even then due to the resin and procedure used you will probably not get a fin that is comparable in quality to good commercially manufactured blades. I'm sorry to be discouraging but if money and time are an issue I think it's good that you know you're better off buying ready blades. Spearguns is a different matter :) Good luck if you do end up giving it a shot.
