How would you use this info to plan your next dive?
Exactly why I dive 2 computers, I have also always had a backup for tank pressure. I have never had to call a dive early or lost any dives in a series due to equipment failure.
Yes, go to tables. That is not the question. How would you do that, since they are not useful for multilevel dives as you likely are doing?I'm sure you know the textbook answer.

This us what I don't understand. If you are just going to stay out of the water for 24h, what value does the bottom timer add?However, it is still a better choice than diving with one computer in my opinion.

Gotcha. That makes sense to an extent.Regarding Option 2, I would like to know depth, ascent rate and time of safety/decompression stops in the event of primary computer failure, but you cannot plan subsequent dives if you go down this route. However, it is still a better choice than diving with one computer in my opinion.
I think we're all agreed that you should end the dive if your primary computer fails. Knowing your depth and time on a backup comp is valuable data assist for a safe controlled ascent along with a safety stop....and having once back on the boat or shore, having overall time and max depth data on your backup is also valuable "bonus" data in that it might help you make personal decisions on how long you feel you need to wait prior to resuming diving or flying.If you are diving with one computer and it fails, you should end the dive. The only way knowing your depth and time would help you is if you were on a true square profile dive and could use tables for the next dive. If you are on a typical multilevel dive, it does you no good at all.
John.....unless I am misunderstanding your answer to @MB NZ comment, you seem to be saying that you feel you could make a safe ascent on an NDL dive without having any depth or time data. I'm guessing that with your experience that you probably could. But for many divers, including myself, here in the Puget Sound with low vis and no visual bottom or surface reference, a controlled ascent with a stop at 15-20ft could be a challenge. And then there's night dives to consider. I guess you could simply carry a back-up analog depth gauge or track bubble rate...... but isn't it better to have the added data that a computer provides?I guess I'm funny that way. I just think that I can make a safe ascent from an NDL dive without having that. Apparently you would need it, in which case you definitely should carry one.

I just can't see any valid argument against that comment...It helps you to get out the water safely.
