Did you create a cylinder for the AL80? If you try and change a cylinder, it doesn't accept it. .18 sounds comotose to me.

Yeah I changed cylinder 1 to 80 ft^3 for the size and 3000 PSI for the working pressure. On the sharkdive at Cara y Cara it said I started with 2840 psi and ended with 960 psi. Dive time was 40 minutes. I notice that the total gas in cylinder says 538.1 ft^3 - no way right?
Something is wrong with the program! I switched to cylinder 2 and then back to cylinder 1 and input 80 ft^3 and 3000 psi working pressure and it now says that at 2840 there was 75.7 ft^3 in the tank and that I used 50.1 ft^3 on a 41 minute dive. I'm no math major but that works out to over 1 CFM or about .5 SCFM on the sharkdive but the program still says .13 scfm

Well, it's called an Aluminum 80. :laughing:
Click on your name in your logbook and New Cylinder to add the AL 80.
If you know the average depth, you can calculate your SAC here:

mccabejc:Hold on folks...Let's wait up for the guys who'll say that comparing SAC rates is bogus.
well.... comparing SAC (or rmv if you prefer) ... how much you breathe ... is simply that, how much you need to breathe. While it may change over time, it's more important to know how much you use, so you know how to plan your dives.

Drysuit RMV: .48-.54
Wetsuit RMV: .42-.48
My lowest RMV was .36 but that was an unusually relaxing dive.
I do my calculations with the calculator at spearfishing.org also.
Aloha, Tim
btw - Lately I'm the first to call a dive due to low air... so presently I'm the "air hog" of the group.

.45 what's that?
I can hit just below 0.5 on a night dive single tank wetsuit *maybe*
More usually 0.5-0.7 in drysuit, doubles and stages.

.79 to .85, but sure hope I'm able to get that down as I gain more experience. Time will tell.
