GravityGirl 0 #2 October 28, 2005 A two pin has, well, 2 pins. The Racer container system is designed with 2 reserve pins on one cable. It distributes the tension over two pins to minimize hard pulls that could be inherant with an external pop top. ~~~~~~~~~~~~~~~~~ Peace and Blue Skies! Bonnie ==>Gravity Gear!

riggerrob 558 #5 October 28, 2005 2-pin containers were fashionable before Cypres was introduced (circa 1991), but have slowly faded in popularity, because 2-pin Cypres cost $125 more. Mirage re-designed their reserve container from 2-pin to 1-pin when they re-started production in the 1990s. Now the only 2-pin containers still made in significant numbers are Racer and Strong tandem. You can install a 2-pin Cypres in a 1-pin container, just neatly coil the extra cutter and cable in the pocket. However, installing a 1-pin Cypres in a 2-pin container will not save your life ...

Rob, Is that actually legal? ... you're usually pretty up on the gouge, so I'm guessing that it is per Airtec. I had thought that one of the pre-firing checks the 2-Pin Cypres' did was a continuity check to both cutters, and if one failed, it didn't fire?... thought I heard that once somewhere. So, if you used a 2-Pin Cypres' as a 1-Pin, like you describe, you may be adding the potential for another failure mode. Anyway, not that Cypres is an excuse not to get your main or reserve out on your own... Quote Share this post Link to post Share on other sites
outlawphx 1 #7 October 28, 2005 If you have a Cypres with a field replaceable cutter (one pins since Mar 95 and two pins since Sep 99), you can convert between a two pin and one pin without sending it in for service. Otherwise, I believe SSK can convert it for you when you send it in for service. http://www.cypres-usa.com/cypres06.pdf Quote Share this post Link to post Share on other sites

thepollster 0 #13 October 28, 2005 Quote Rob, Is that actually legal? I'm not Rob, but I can answer this with absolute certainty. It is legal, and if you look on the SSK website, you can find the answer. It isn't very common, though, and I think I've only seen it done twice. The second cutter doesn't know it doesn't have a closing loop through it, so there is no reason not to do it. Quote Share this post Link to post Share on other sites

QuoteI understand this. Then you realize there wouldn't be a continuity problem and wouldn't be adding a failure mode. Derek HnS, If it is true that a 2-Pin Cypres will not fire if one of the cutters fails a continuity check during the processors pre-firing checks... again, I'm not sure and will query Airtec... but say that is true... then if you were using a 2-Pin Cypres as a 1-Pin, and by some reason the extra "stowed" cutter was damaged, then the good cutter inplace with the reserve loop passed through it would be of no good... i.e. unit senses 1 of the two cutters failed, doesn't fire when it should... it doesn't know the failed one is stowed. Of course if this was a presistent condition, the unit may not even turn on in the first place and it would all be academic. Quote Share this post Link to post Share on other sites

Hooknswoop 19 #16 October 29, 2005 Ah, OK. I see what you are saying. I don't think it is an issue or we would have heard about 2-pin rigs with Cypres's failing from broken wires. I think it is better to have a 2-pin Cypres in a 1-pin rig than no Cypres with almost no chance of it failing from the second cutter breaking.

koppel 3 #18 October 30, 2005 I was packing a Talon at the weekend with a 2-pin in it. The owner was with me and during the course of packing we discussed how the Cypres worked as I was feeding the loop through the cutter. Interesting comment from him was "..how long before we need an electronic eye on the cutter to ensure the loop is properly located?" If I ever get that bit worng would someone please buy me a membership to the local golf clubI like my canopy... ...it lets me down. Quote Share this post Link to post Share on other sites
