  • Most visible color on the sea bottom?

    If you drop a knife and it goes to the bottom, what would be the best color for the knife handle so it will be most visible? I guess it depends on what kind of bottom it is; reef, sand or something else. I'm interested in a hi vis color for all environments.


    While we're at it, who thinks it's important to have a high vis handle on a knife? Me I've never lost a knife, so I don't care, and I don't like bright colors, they remind me of scuba weight belts. If it's important to you that the handle be a color other than black, what is the color?


    On another note, what are the chances that a bright handle on your leg or waist will spook a fish?


    And finally, if you really liked a knife but it wasn't available in a high vis color, and the color was really important to you, would you be against a little spray paint every once in a while? Or would the spray paint not adhere to the plastic at all?

  • Pigtail snap & swivel for speargun muzzle bungee

    Quote from greekdiver

    Another thing I notice is that the rope is too thick for the design of the snap swivel. The snap swivel is very strong only where it curves. I think wire or thinner dyneema equivalent to 400lb mono thickness is a more accurate test.

    Good observation, I agree. It's definitely worth testing again with thin line that's stronger than 400lb mono. It will also be interesting to see if the line fails before the snap.

  • H Dessault footpockets new production - soft tendons

    It's a myth/fad, and companies are trying to meet market demands. Those that tried it early enough already went back to moderate stiffness tendons. For example Pathos; 1st generation footpockets were too soft, the result was broken carbon blades and customers complaining. 2nd generation f/p were too hard, Pathos overcompensated and went too much in the opposite direction. The result was fins too stiff and again customers complaining. 3rd generation, finally after myself (and others I'm sure) asking to make the tendons softer Pathos responds with nice moderate stiffness tendons.


    The function of the tendons is to give the carbon blade support, and evenly distribute the stress of bending away from the footpocket. When the tendons are too soft and provide no support, the blade will bend most at one specific spot an inch or two past the foopocket, then there's a bigger possibility of it breaking in that spot. That's why this design from Sporasub has never been used for anything but plastic blades.



    Marco, to you it seems like a good idea probably because of the fins you're using, because they appear to lack tendons completely. On close examination that huge flap in front of the C4 footpockets weighs just as much as conventional tendons and provides the same support.

  • Nearly 600-Pound Bluefin Tuna Sells for $736K in Japan

    The main reason behind it is marketing. The buyer wanted the publicity and prestige that comes along with it. Still the money goes to whoever caught the fish, after the fish auction house takes their cut, so I'm sure they're celebrating. They won't stop until the tuna are depleted.

  • First gun build underway

    Nice looking handle plate Mike. With a coating I'm sure that grain will look delicious. Make sure it's not too fat to grip.


    Khalel, the only real safety is loose bands, and even then you have to be careful where the gun is pointing. As such safeties are useless, except to protect that once in a lifetime fish swimming by as you futilely squeeze the locked trigger having forgotten to remove the safety.
