Na. When I first started diving I could clean up a 105 steelie in minutes...Storm:
What is average surface air consumption?

Has gotta be done! When you are paying $110 for a two dive day out here, and no shore diving, it is painfull. Oh that doesnt include tank fills.Storm:You know what they say about boats....they're a large whole in the ocean into which you get to pur all your money.
Now we get 4 divers on the boat and the fuel is around $20-30 for the day depending on how far we go. My brother is a mechanic who specialises in small engines.... sweeeeeeet.

Male, 5'10" 220 lbs SAC= .55 on average. I guess I'm doing pretty good- I was 1.1-1.3 at first- I've gotten a lot more relaxed in the last 10 dives or so.

Yeah know the feeling. My cousin is a diessel mechanic, and if it wasn't for his talent we would have beached my old scow years ago. As it sits she's high and dry this year with a torn up transom, beat up hull and leaking motor head.
Now I've got make THAT desicion...fix her or scrap her. It would probbaly cost more to fix so she might not see the water ever again. She's only a small inland water fishing boat but you still get attached to them.
Oh well...next year we'll float a new one...hopefully.
Good luck and enjoy.

I am the air hog of the group. I am always the one to hit turn pressure first. The other guys I dive with are .43 so I need some work

I´m curious...I don´t have the numbers at my fingertips right now but I´ve noticed that I use significantly less air when in my doubles than my single tank...
My single is a 80cft while my doubles are ~116x2, all steel. For recdives that would normally use up my single 80cft, I only use 50% of one 116 when in doubles...
Has anyone else noticed something similar?

You're kidding me right? A .48 RMV and you think you have work to do? What I wouldn't do right now for a .6 let alone a .48!

I'm amazed also at what I'm seeing posted. If I don't have any prior knowledge of the SAC of an insta-buddy, I assume 0.75cfm. That's what I see as the typical SAC of an occasional diver that has never calculated his SAC. 0.6cfm is my guess at the more typical SAC of a frequent diver.Divin'Hoosier:
SB members tend to be more serious, hardcore divers than average. And then just the subset of those that have low SAC are posting to this thread.
The numbers posted so far are NOT average.

I agree with you, Charlie.
I think if one were to get on the average dive boat and run an analysis after the dives, the average SAC rate would be somewhere between 0.60 and 0.75.
No empirical data here, just speculation.

Charlie99:
Thanks Charlie. I'm still floundering the in .78-.88 range. Those have all been cold water in full 7mm with hood and gloves. Local quarry and two dives in Monterey. I certainly won't ever do any "tricks" to try and get it down (skip breathing). Way too dangerous and it's just not that important. But it would sure be nice to see it in the .5-.6 range. Hopefully it will come with time and increasing comfort/relaxation in the water. If not, no big deal. It's still a blast to be underwater!
