New Computers Reducing Bottom Time

[BRT]

Sorry. I set it to 1.4 and still have 40 minutes.

You should read up on PP of O2 so you understand how they affect your diving. Could affect your lifespan.

I don't think there is any way that Scubapro's Buhlmann ZH-L8 ADT MB will give you 40 minutes at 80 feet on air, check again. This is a middle of the road to conservative algorithm.

I'm looking at it right now. 80 feet for 40 minutes, 90 feet for 31 minutes, 70 feet for 53 minutes.

Sorry I'm skeptical, The USN table has 48 min at 70 feet, 39 minutes at 80 feet, and 33 minutes at 90 feet. These times are significantly longer than any computer. Are you sure you are looking at air?

You're correct. I still had it set to 32% from my last dive. I haven't really looked at all the features of that computer yet.

It's good to know what to expect, I have spent a fair amount of time trying to understand deco algorithms

Well, the good news is it obviously does not default to air (or worse] after a dive or a day, like some (stupidly and irritatingly) do.

Mine gives me 54 minutes, wait..... it is still set to 36%

Honest mistake, no harm, no foul

Is that your first or second dive...no no no j/k

True but it really does illustrate the increased bottom time of EAN in the 80' range. Correction, NDL time value.
