Why a breakaway on your primary reg?Corigan:I have all attached with cave-line except the boltsnap on my primary 7' hose. That I have attached with a breakaway o-ring.

It is for a few different reasons. Basically it makes it a fast-access point. If it is clipped off and you need it now you can just rip it off the d-ring. This is if you are dealing with stages, switching around regs, etc. If the primary is clipped off while decoing, OOA diver comes to you and you need to donate with your backgas then you could easily rip it off your right shoulder d-ring and donate. Since I don't use stages this doesn't apply to me, but I still use this method for clipping off my reg on landsince I saw it hit the ground once on the 7'. Also during dives I will sometimes clip off my primary and use my safe second to make sure it is fully functional and working properly. When I do this I will clip off the regulator. If an OOA diver came up to me in this state it would be easy to remove the primary from the d-ring/boltsnap with a simple tug. Nice and quick. The breakaway is plenty stable for everyday usage. I have never had one break un-intentional on me, but I did do plenty of tests and saw what little strength it does take to break.
