Leaky Reg?

[Blue Sparkle]

Although the OP did say he dived this reg one time previously, and noticed unusually high air consumption. He didn't mention any noticeable leak/bubbles though, so

Constant or very large leaks are easily detectable by a dive buddy in good vis conditions.
I'm not so sure that an intermittent leak, coinciding with the inhalation phase of breathing and possibly localized to the first stage, would be picked up by the diver. A sidemount diver would have a better shot at identifying the issue since he can visualize the first stage. An observant dive buddy might notice, but maybe not.

The unusually high air consumption suggests loss of air from the reg system somewhere (leak?).

Well it's a leak or a massive increase in lung volume overnight

my bet is the computer or qd is bad and the high air use on the dive he did use it resulted in a tank that wasn't really empty but the computer reading that it was. to bad we dont have a second computer to put on the first stage with it to confim this.

I guess it's a matter of situational awareness.

I would hear any air loss from my regs (and my hearing is bad, trust me).

Maybe, due to experience, I am just better attuned to listen for such things.

There's been many occasions where I've heard a noise, pulled out my mirror and located a small air leak.

You know, this is an excellent use of a mirror. I've never felt the need to use my signal mirror underwater. A suspected leak coming from my first stage would be a pretty good reason to use it. Thanks for pointing that out.

I was doing a dive at Two Harbors (Catalina Island, CA) a few years back when my buddy and I found a metal spatula. It must have fallen off one of the nearby boats. We had the best time playing around with that spatula. We could use it to see the buddy team behind us. We could also use it to see around corners. I suppose I could have even used it to visualize my first stage if I were so inclined. Several uses for that cooking implement.

Same benefit with entanglements...

Ooh, I like the mirror tip. Thanks!

(I would just have "liked" your post but that would not have singled out the mirror part.)

Update: I will be dropping the reg off at my lds, who is actually a dealer for my computer, so he'll be checking not only the mechanics of the reg, but also the accuracy and connections of the computer as well. I'll keep you all posted as I get new information

Thanks very much to all that have responded so far
