    The Freedive Store ships to Australia with USPS express / EMS or Priority service. I'm assuming yours is a heavy wood gun, a 12lb speargun is $106 with Express service (3-5 business days). A light carbon gun approx 6lb runs about $75. Priority is cheaper and takes more time. Both are sure as there is tracking and delivery confirmation, but Express tends to zoom right through.

    1/16" = 1.59mm I doubt they can do 1mm.


    The diamond knot will be difficult to insert into the small ID rubber. But it's not necessary, I never had an overhand knot (on a loop) come out. Nor a double overhand on a conventional wishbone. In small or regular ID bands.

    I started with small ID rubber 5 years ago, as a way to minimize water intrusion into the band. At that time small ID speargun rubber was unheard of. I get a lot of inquiries from Europe about it, but rubber is not cost effective to ship. I'm pretty sure Sigalsub started offering this rubber after having seen that I do. In any case you don't make money on rubber, but it is the mark of a discerning spearfishing gear manufacturer. I expect that in the future the big names in the industry will offer it too. The two things standing in the way of that are, increased cost, and the perception that it's harder to insert wishbones into this rubber. I proved a while back that a wishbone can be inserted in a hole poked into solid rubber. A solid rubber speargun band would be ideal, unfortunately the manufacturing process doesn't allow it. The smallest ID possible is 1/16".

    George's is for a straight wishbone. Good to have here for reference.


    Marginatus, thanks. I will try the double sheet bend, I just pull the bands apart as hard as I can to test. But using a spectra wishbone without a knot.. I'm skeptical. Still I hope it works as you're right, it's a cleaner look.

    LB, don't know about the replaceable bit, but after tying the distance between the bands is 2".


    marginatus, that's a nice knot. Please post a link to instructions. BTW there's a chance your wishbone will slip through the knot, even though it has a small lip from melting the end. I put a knot on each end like in Marco's pic.

    First, welcome to Speardiver cksea.


    That is too funny, grogan writes "someone sent me this today", what a weak attempt to disguise the fact he lurk here daily. But for shits and giggles imagine this is the kind of undercover stuff grogan's "informants" feel is important enough to pass on to him.. To be sure he's reading the thread just check the grogan meter :)


    None of the Speardiver guns have it, so no. Also none of the wood guns I built in the past. The replaceable wishbone system is better all around for these reasons.
    1. You can adjust the length of the wishbone ie. shorten/lengthen the bands without cutting rubber.
    2. The wishbone can be replaced on the water if necessary. I always keep a couple of extra wishbones in my kit.
    3. Wishbone often wears out faster than the rubber, you can quickly change it without cutting/retying the bands.
    4. The band insertion slot weakens the speargun muzzle, with tie-in wishbones it's not necessary.

    Dustan, there are more than two places in the US where rubber tubing for Spearguns can be ordered. Of the ones you know Kent Elastomers produces the less expensive and inferior product. Another one that you may know doesn't actually produce the rubber in the US although the company is US based. This is all trivial anyways, Speardiver rubber stands on its own and that's how I want it to be. I'm only pointing out some wrong notions about speargun rubber.

    I'm a practical man but this strikes a cord in me. I do believe spearfishing will keep me young till the day I'm gone. Or maybe it's because I'll always be young at heart that I spearfish :) who knows.. it's a nice legend. Thanks Don.
