Need Help chosing a Wrist Computer.

[Peter_C]

I STILL say the numerous advantages and conveniences of an AI hoseless wrist computer outweigh the inconvenience of a "possible" aborted and early terminated dive due to a computer failure.

I own a very nice Uwatec Smart Z that is AI. A long time ago I took off the transmitter because it interfered with my long hose on doubles. I put a pressure gauge on a 24" hose not long after I started diving for redundancy and to make setup easier (Remember your computer has to be on and near the transmitter to check pressure before kitting up). Never actually missed the transmitter since I used air pressure to calculate when I needed to head up, not my computer telling me when. I did use the computer to calculate my NDL's but now just use gauge mode.

BTW My Uwatec Aladin 2G was under $400 with the DSS mount.

What conveniance? Minus one hose??
Im guessing that was a NO to selling both yours for 400.00?? ( Joking )

I wouldn't part with either my hoseless AI wrist computer or my backup non AI computer. But the Op might find a deal on two used ones for close to that amount.

The convenience other than one less hose (which I agree isn't much but I still think "less is more") is:

1- The computer constantly monitors your remaining gas, your SAC rate, theoretical nitrogen and oxygen exposure and NDL limits and figures which is the most limiting factor and provides a digital display of dive time remaining.

2- Your gas supply and depth and nitrogen exposure is right there on your wrist, no fumbling or reaching for or unclipping a gauge cluster that is another source of drag or a "reef wrecking ball".

3- Built in user configurable alarms audible and visual if you screw up and get complacent or get so task focused possibly due to narcosis.

4- Downloadable data so you can check your dive profile and (I think) get a very accurate SAC rate. (I never used this feature).
