Glad to bring back nice memories, but I fear it brings back also not so happy ones. Let me explain.
You were satisfied with the Aladin, as were many divers and dive buddies of mine, but my experience was a bit different. I rent one for a weekend : was brand new, I knew very well the head of the LDS, he got it out the box in front of me, then I went to dive.
Underwater, I couldn't stand the thing, had an utter dislike for the way the info was given, and on the third dive, it went out. Blank screen.
Back at the store after that weekend, my pal just told me : it happens, don't worry. Next time I went diving, rent another one, same story, blank screen after less than five dives. Give it one last try : same again ! My friend began giving me a bad look...
Next summer, I bought from the same shop the Cochran/Beuchat Maestro Pro. Very easy to use and clear to understand. (By today's standards, I fear it might have been too liberal on NDL, but that's another story. It was the 1st computer (and sole) computer of the market to have a user changeable battery... But... Finding the right battery, which was rather exotic (ref. LR7 if I remember correctly ) in France at that time, was hell !!! One must remember it was around 1994 so the internet was not what it is today, meaning : nobody had it home. The damned battery was only sold in electronic shops and photo shops. What time I wasted to find only one, grrrrrrrr !
Nightmare wasn't over when you got the damn battery. If the cap wasn't screwed with the right number of turn, the blasted appliance wouldn't start ! No indication in the user manual, you had to try several times...
To make things worse : this computer quickly shown reliability problems. Many went back to Beuchat and it got the computer a very bad name. Not mine. I was probably the last guy to dive one, until it just conked out in 2000 when I tried to change the battery. Gave a call to Beuchat, who couldn't care less and told me to see with Cochran who told me to see with Beuchat. Perfect customers service on both parts... I was a student back when I bought that computer, remembering how I had to scrounge for every penny to get it still hurts.
But Davy Jones be praised, my following diving computers were much more trustworthy.
