Pro Plus II problem/question

[comet24]

Finally got my Pro Plus II. Decided to test it out on a few dive in the Aquarium the other day. My depth was 18' most of the time was shallower. One problem was that it would show only a few minutes or zero for dive time remaining. This was with over 1500 psi in my tank and I should have had hours of NDL. Then at times it would show what I would think was the correct info but most of the time it was telling me I have very little time left. Is there something wrong with my computer. Want to figure this out before I take it to the ocean in a month.

What probably happened is that when you were shallower (10 or less feet probably) it went to surface mode and was not in wet mode which is typical operation. Most computers have to go to 10ft or so to be activated.

Hope it's that easy. Most of the tank I was in is only 7' with a small 18' part. Now I really want to get wet again and try it. To bad it's winter here.

That is more then likely what it is doing - it just thought you were on the surface so stopped logging. If you have a cable you can hook it up to see. Also see how many dives it logged - it might have logged a couple for one if you came up to 10~ft or so and went back down.

No cable yet wanted to make sure I liked it before I invested in one. Not sure how I like the dive time remaining thing. Tank pressure has always worked for me. Really want to get it to the ocean for some real dive but that will have to wait till Feb. when I am in FL.

I've got the same computer. The manual states that it'll go into interval mode at 3 feet or less. I haven't done any shallow dives with it, so I haven't had that problem, but the rental computer I was using before would end up going into surface mode very often when I would go river diving with the bottom ranging from 8 to 15 feet.

Make sure to post again after you've used the computer in a deeper dive. I really like the DTR feature on AI computers as it tells you exactly how much no decompression time you have, not necessarily air.

I think you'll like it once you get used to it. Tank pressure doesn't always give you your best info. Sometimes you might want to know how long till no-deco.

Reading what I posted I should have been a little more specific. I not sure about it's large display of BTR because with a quick glance I don't know what the limiting factor is. Such as NDL or gas supply.

I have the same comp. Bottom time remaining is based on NDL. Gas supply time is only calculated on the bar across the bottom.
