Thanks, I always knew I was a heavy breather, but I was kind of content with the "nicer numbers" from the NAUI wheel sac calculator. Now I need to focus more on getting my sac rate under control. I was carrying WAY too much weight as Art and shooter can testify. They encouraged me to drop 10 pounds of carried weight since then. My sac rate varies dive to dive from .54 to 1.07 with the spearfishing calculator and seems to average about .79. Thanks again.

Anybody wanna buy my "Slightly used" Naui sac rate calculator wheel?... No?.... anyone?... ok I will use it for a secchi disk ;D
