Do you really understand your computer, or is it a threat to you?

I dive with TWO computers of different brands and algorithms.
The Aladin is my primary while the other is the back up.
In all multi-level dives that I had done the initial ndl between both was very similar but on the ascent the Aladin has shown slightly less until 9m when the difference was day and night!!!!
Can I say Aladin is safer? Of course NOT because I cannot prove the other is less safe.

Dive computer is safe but NOT the divers.

A man with a watch knows what the time is. A man with two is never sure.

I think it is interesting that there are people out there diving with computers that are older than I am. I am honestly a little surprised that they still function well after this long.

Centrals have you replaced O-rings or components of that computer? Do you test the accuracy of the depth gauge often? I'm genuinely curious.
