Actually the original post was just asking about the pros and cons of using a backup computer with a different algorithm than the primary......and then someone later suggested using gauge mode on the backup....
Then the thread segued from there like they normally do.
I was basically responding to the comment of making a safe ascent and safety stop with NO data..... and still think that would be difficult on a dive with little to no visibility.
In the tropics or any great vis location, then I agree that surfacing safely from an NDL dive with no available data should not be much of a problem.
