I'm talking about liveaboards and vacation divers. And suunto has the largest share of the computer market right now .. for better or worse: makes finding a buddy easier and simpler. That said, please let me know what your experience has been in buddying up with a nitek!
I would guess that when you combine all the ones made by the same mfg that makes ocianic, they would be much larger...just a lot of names to ID though.
My normal buddy uses Suunto,,, I dive a Galileo... don't have an issue.
I have dove with people using just about every computer made, don't have an issue.
If I had to pick, the choice would be easy....Nitek.
If you want the computer to absolutely make sure you don't do anything stupid... get the Suunto, but if you do. ..don't every accend too fast (even on the bottom, but particularly the last 15 ft) or go back into the water until it says it is ok... or your dive time will be shortened.
I have never seen, on any trip, anywhere in the world, more than maybe 1/4 people using Suunto... which is pretty good, considering how many different brands there are, but hardly "everyone"
