In water testing, does anyone notice a difference pre and post dive? In my limited experiece with 7 cells so far, all indicate 1.35-1.4 @ 1.5-1.6 at end of dive.
Yes. But not by that much. My own theory is that this is due to the loop being saturated with water. Analox say that their analysers need to be adjusted by 5% if used in 100% humidity. I can't see why the same doesn't apply to breathers.
