Looking for a dive computer

[ScubaDo]

Thanks Mateo for restarting this thread.  Since my last post I got a new Uwatec Smart Z wrist computer with hoseless air.  For newbies here is some points to think about not listed above.  My computer displays normal info plus temp and estimated time remaining.  Having a wrist mount is very easy viewing and very helpful in Rescue diver course.  I could watch my ascent control the victims BCD and hold victims regulator in mouth with one hand and use the other hand to hang on tightly to the victim.  Wrist mount is also very handy if you get to play with a DPV, you can watch your gauges without stopping.  Although the motor may interfere with air gauge, all you have to do is release the trigger and wait a second to reconnect.  As a side note, you can't mount a compass on a DPV, needle points to the motor.  The estimated time remaining helps you learn to control your breathing.  Smart Trak software is nice, could use some improving on some of the features.
The disadvantages to my particular computer; I can only use one gas on a dive, a disadvantage if you decide to get into tec diving.  The backlight can be set to a maximum 12 seconds.  Very annoying on ascents during night dives.
