Dive Computer question

[DetectorGuy]

I use a Suunto Vyper on my console and a wrist mounted Tusa IQ 700. I am a dyed in the wool Agua Lung fan and I dont know for sure but I think Suunto is owned or at least in bed with Aqua Lung. Even with this relationship, I like the Tusa much better. The computer is more user friendly, It was cheaper (even if I didn't win it at a Smith Diving treasure dive), and a person can switch from air to nitrox during the same dive. The data retrieval after the dive is straight forward. Neither one of these are air integrated, and I am ok with that. It is hard to beat an analog SPG. As far as the need for a built in compass... I dont think anyone really needs this. In my mind built in compass's are just a trinket and not a real deal. Suunto SK7 compass on the back of the console works just fine for me. Why add to the task loading when you are at 100' pitch black and your primary light is starting to dim. You start your ascent and then you try to stroll through the "pages" on your computer screen to check your ascent rate against your actual depth. Then roll to another page to get your air quantity. You switch to the compass mode to head South back to shore and the battery in the computer just dies... Oh yeah then add in the narcosis and the other two or three things that you have come up unexpectedly... these cool gadgets can get people hurt if you are not careful.
