When I get together with my Rebreather cave buddies, we carry a "Rebreather Long Hose" that can connect to a female LP fitting (i.e., to the manual add O2 counterlung hose) to a male LP fitting (i.e., to the manual add LP QD counterlung fitting). We also have, like most Rebreather divers, an extra hose with an LP QD fitting on all bailout cylinders. With this, we can share air utilizing *any* onboard/offboard gas amongst anyone who is in need. It's pretty handy. Coil it up and place it in a dry suit pocket or wherever. It cost about $100 to make and I don't have to carry another cylinder; my buddy has it/them. So, we can share gas just like in open circuit.

Credit should go to Gregg Stanton (Wakulla Diving Center) for that one.

Wow, never thought of that one, that's pretty cool. So did you add a second LP hose on the O2 side or you rely on the solenoid while sharing O2? I can see how this could work, just have to be careful not to rip the manual add valve off the CL when going through tight spots especially in high flow. Probably easily solved by simply holding on to the hose. A couple of questions if you don't mind:
Do you practice this O2 sharing as a team on a regular basis?
What do you use as a signal to prompt this exercise and avoid confusion such as "out of dil" vs "out of O2"?
I would imagine you bail out first, then start the "plumbing" and then go back on the loop, did I get this right?
Thanks for your reply, very interesting.
