  • Punta Mita

    It's too bad that it takes a serious accident for some people to really learn this lesson. As we've found out a couple of years ago spearguns are dangerous when stored in the upward pointing direction even when unloaded. A few weeks ago I was on a boat where the guys sat on the transom with the guns loaded as we moved spots. I'm sure it was comical to watch me escape over to the bow. It's considerate of you to accommodate divers who don't feel good about it.

  • Differences between Epoxy brands

    Thanks Phil. I saw that with fast curing epoxy a lot of heat is generated at the point of curing. Are you saying that with slow curing epoxy there is no such point/no heat? I just assumed that the same thing happens with slow curing epoxy only much later when I'm not around to see it.


    Also with something like West Marine epoxy where the resin stays the same and the hardener controls the curing speed. Will the slower curing hardener produce a better bond than the faster hardener?

    Thanks for the recipe Chris. I don't know if you saw it we have a cooking section. Give me the word and I'll move your thread there.

    Sunday in need of some upper body exercise I passed on my Nitrogen tank and fill setup, and attached the stock hand pump. Two espresso and a little techno music later my air gauge was at 21 bar @ 80 degrees.

    Thanks for the writeup Don.

  • Differences between Epoxy brands

    A question for the experienced gun builders. Is there a quality difference between Epoxy brands for small wood bonding jobs. I know West Marine epoxy is the industry standard for laminating gun blanks. But for a small job like adding side stalks to speargun will a 5 minute epoxy, the kind that comes in syringe with a 1 to 1 mix ratio, be good enough? I prefer the convenience of the syringe. Also does slower curing epoxy ultimately make for a stronger bond?

  • One more breath

    Don's post got me thinking.

    Quote from Don Paul

    Last year I started putting a short sealed 25' 3/8'' vinyl tube on my dive light I use for the Cock-a-Roach's.
    On the end I have a mini light that strobes. If I get stupid ( not implying this poor soul did) it helps me find my way out to another breath. The tube can easily be cut with my sharp knife if needed. I'm going to spray dayglo paint through it next week. The hoopers were getting a little too close to me the other night.


    Don

    How much more time will one breath give you?


    I recall some category or record in competitive freediving, where the diver took another breath at some point.


    I've never done this because I never had an air source. But I figure I'd get very little time considering how oxygen starved I am at the end of a dive. Maybe I'll have someone watch me and attempt another breath hold after one breath.

    Quote from John Hanson

    I seem to mentally focus on the gun out of my preripheral when using a longer mid-handle. By using a rear handle I can concentrate on the fish rather than the gun.

    Exactly. My vision is not bad, but I agree with everything you said John :thumbup:

  • GoPro HD Underwater Blurry Fix

    LB, if there's a demand I'll stock replacement housings.


    fuzz, your photos are not too shabby either :)


    Neither the Gopro curved lens nor the replacement lens have screw holes. It's the black plastic mounting ring that has holes. Replacement of the lens is as easy as undoing the screws, taking out the old lens and popping in the new. There is only one position in which the lens can go in so there's no worry of positioning it wrong. There is a rubber washer between the lens and the housing and that's what provides the seal, no sealant is necessary. When tightening the screws of the mounting plate I recommend to do it in a crisscross pattern to tighten it down evenly. I also recommend to try the housing at depth at least once without the camera having stuffed tissue paper into the housing to clearly indicate a leak if there is any. Pursuit Spearfishing Gear will not be responsible for water damage to cameras that had the lens installed improperly.


    Housing and lens disassembled, with new lens on top of the camera.



    Housing and new lens installed, original curved lens is lying next to the screwdriver.
