Thanks everybody for the responses. I can understand the info about the J valve. In all of my years, I have never heard of one failing but I guess it can. I don't know about the SPG's being expensive back then. We all had one so it couldn't have been to much but truthfully, most of us bought our personal dive gear at a military base BX/PX so it was all cheaper anyway.
As far as regulator swapping: I will clarify that with my partner before the dive. If he's in trouble, he can have my spare. I'll keep my primary in my mouth where it belongs. I won't be doing anymore 100'+ or cave dives so it would be a easy shallow free ascent anyway.
Yeah, I know what panic can do to a person. I've drug in a few drowning tourists while I was riding the rip tide currents off of Okaloosa Island and Treasure Island in Florida. They would have drowned me along with themselves if I wasn't ready for it. The funniest one was a little girl and her dad. She had on little pink floaties and had drifted into the rip current. Her dad had swam after her and was near to drowning himself. I grabbed her and let her ride on my chest while I headed for shore but I thought I was going to have to smack her dad to keep him from drowning the both of us. Anyway, thanks again, everybody.
