The O-ring is thinner and can break more easilly if required. OK, the only place you should ever have your long hose clipped off is to your chest d-ring when you are breathing a stage or deco bottle. The reason for making a breakaway clip on a long hose is so that if an out of air diver needs gas in a hurry, they can just grab the long hose and pull it away even if it is clipped off. Alternatively, they could just take the stage reg out of your mouth and you could go to the backup around your neck. In practice, I've found that you really don't need a breakaway clip if you can make a sliding clip. If you use David Shimell's method and you use a large enough diameter o-ring you will end up with a bolt snap on your long hose that can slide up and down. What happens then is that if an out of air diver grabs your clipped off long hose reg and pulls is that the hose will pull through the o-ring and they will get sufficient hose to begin breathing. Once you've stabilized the situation you can get the hose unclipped and get everything sorted out. You can also reach down and pull this reg up to your face without unclipping it if you ever needed it. What I did is go to the local Ace Hardware store and buy a large selection of different size o-rings. They are cheap. Then I experimented with them to find the best size for making a sliding clip that can still be broken away if absolutely necessary. -Kent- -- Send mail for the `techdiver' mailing list to `techdiver@aquanaut.com'.
