What is average surface air consumption?

[ccohn2000]

I'm just wondering how my air consumption compares to others. I have no idea if it's good, bad, or average. I don't seem to run out sooner than anyone else, but I kinda think I might be a bit of a hoover for my size. If you're willing to share your info, here's mine. I'm including lots of stats because I know theoretically it matters if you are a big guy comparing to a small woman. Although my dive instructor is a really big guy, and I am a smallish woman, and I know he breathes better than me.

usual scr as calculated by my vytech is .46 -.48

Thanks! If you have any tips on how to conserve safely, please do!

LOL!!!

I'd kill for that SAC rate... I couldn't hit that if I was laying on the bottom reading a book.


From the looks of your picture, you might conserve a bit more if you clean up your trim, and clean up all those danglies.

ccohn, I don't know if you are diving with buddies with gills, but you are not a hoover!

0.60 is pretty normal for me, 0.75 is stressed, 0.45 is a good day. 5'10", 200#, male, drysuit, cold water.

.4 to .8

Usual cold water sac is mid to low .5s usual warm water sac is mid .4s low 4s if drift diving.

I had a record .8something a few weeks ago - cold very rough water, super low viz, a period of about 15 minutes fighting a very strong current with all my might and thinking there was a resonable chance I was going to be smashed into a million pieces on some wash rocks. Good times.

Hold on folks...Let's wait up for the guys who'll say that comparing SAC rates is bogus.

Does anyone know if the Suunto Dive Manager 2.1.3 is calculating everything correctly? I just made 26 dives in Roatan with a new Cobra and my SAC's averaged .13 This sounds a little low to me. It does make a difference when I input a different working pressure. I was using 80 ft^3 and 3000 psi as the working pressure. The Cobra was keepng track of initial pressure, final pressure, and time. Not that it matters but I am just curious...

I hate comparing SAC rates to females. My normal slowly moving around is about .85.

Ugghh... my vyper says .65 is the best I've ever had on a dive. And, I was practically motionless on that dive.
