A friend of mine got a premature opening during a freefly jump, because wrong kind of spandex was used for the BOC packet and the wind has blown his PC out. Result? Out of sequence deployment, cut-away, reserve ride. Of course not all the spandex BOC are the same Quote Share this post Link to post Share on other sites
skydiverek 63 #32 November 21, 2006 From Bill Booth: "I tried making hand deploy pouches out of Cordura 20 years ago, but quit because I had so many complaints of hard pulls. They work fine for some people, and are dangerous for others. The reason is that there about a dozen sizes of pilot chutes out there, and even more ways to pack them, and I have no idea which pilot chute the user might try to cram into the pouch or how they might pack it. Spandex pouches almost never cause hard pulls, because they take any size pilot chute, packed any way you can think of (well, almost). It's a simple as that. The real solution would be to combine the toughness of Cordura with the stretchness of Spandex. Luckily, such a material already exists. It's called (no brainer) Spandura, and you'll find it on all my drogue pouches. (A word of caution...There are at least 10 different styles of Spandura. Be sure you choose the right one). " and "I tried Cordura pouches with elastic mouths 20 years ago, but had a lot of complaints about hard pulls. Going to Spandex pouches solved that problem. It was a godsend to manufacturers, because we have to put a pouch on a rig that will safely allow the use of ANY size pilot chute, made out of any material, from a 36 inch F-111 to a very slippery 18" ZP. It must be easy for the smallest girl to extract, but stay in the pouch during a 300 mph head down dive. Nothing I've tried can do all that but Spandex. But, as has been noted, Spandex is easy to damage, especially on tandem rigs. Boy was I glad when DuPont combined Spandex with Cordura to make Spandura. It has the stretch of Spandex and the toughness of Cordura. It comes in dozens of styles, so it took a lot of experimentation to find the right one, but it sure paid off. We have been using it on Sigma Tandem systems for about a year now, and are very happy with the results. It will become "standard" on all Vectors this month. Who says you can't have your cake and eat it too. I'm sure other manufacturers will eventually "discover" it too, and it will become the industry standard." I heard that all sport Vector 3's get Spandura pouches by default now. Quote Share this post Link to post Share on other sites

You know freeflying is cool so freeflyers should always look cool.... Quote Share this post Link to post Share on other sites

icevideot 0 #38 November 22, 2006 Lots of students use them, and maybe a few people with certain disabilities I would guess."... this ain't a Nerf world." Quote Share this post Link to post Share on other sites
ZigZagMarquis 9 #39 November 23, 2006 Quotebeen looking at the site again, whats an SOS handle? Single Operating System... one handle, usually on the left side of the rig... pull it, an it both cuts-away the main and deploys the reserve. Quote Share this post Link to post Share on other sites
