Hi all,

Press it all the time ..... fly my unit manually - solenoid is my back up -

Benefits to me include:

I'm kept on the ball, don't get lazy & have to monitor my PPO2 constantly.
Less chance of the solenoid jamming open.
Rig set to at 1.2, fires if I am unable/too busy/forget to keep unit at 1.3.
Less drain on battery (re solenoid).
If solenoid fires at 1.2 - the sound is an excellent alarm that I do not usually hear during a dive.

Cheers all.

This is a quite common and sound practice i think.

Only once, when the unit failed to maintain setpoint . . . . to this day, I still don't know why. It went back to AP, they sprinkled it with pixie dust and it was fine after that.

As to why I stayed on the loop . . . I knew how to deal with it so I just didn't see the point of coming off it.

Why didn't you ask AP for an explanation as to why the Rebreather wasn't keeping set point, i would wan't to know if it eas my unit!?

I had to go the other way just this afternoon, pressing the dill button after a high O2 warning, whilst practicing an emergency ascent from 30mt and maintaining the unit on 1.1 with the solenoid stuck open. Things got a little out of hand, when i added too much O2 and found myself at 1.85, but i stayed on the loop and did a QUICK dill flush!

I did, but after some muttering about re-crimping ends and rusty springs, i switched off. . . it just didn't stack up against what had actually happened. Whatever they did sorted it, but i don't believe it had anything to do with one of the molex connectors. It had all the charachteristics of a sodtware glitch, but far be it from me to suggest that was actually the case.

Jim,

It sounds like you really want to be a Kiss diver, I will swap my classic or sports kiss for you Meg if you like

Louis

Louis,

Shouldn't that be 'Classic AND sport kiss for the Meg' - One of them surely wouldn't be a fair trade.

Have a great weekend all - going down the garage to sort the unit for tomorrow's dive. All the best.
