I have been diving for about 10 years (400+ dives) and for about the same amount of time I have been diving with an Uwatec wrist mount computer (don’t remember what model). I just changed my computer to the new Terra (that’s the same as you are reviewing but without the transmitter) and I went diving for a week in Cozume.

I have to admit, I am a little bit dissapointed with the new computer. I disagree with you, I think the screen is hard to read. The dot matrix display they are using doesn’t have enough resolution and whoever is th eintern that created the UI should go diving a little bit first. True, I like their menu sytem and I like the buttons.

It is usualy easy to say “I don’t like it” without giving any reasons so here are a few things I didn’t like (I have to add I write firmware in my day job so I am pretty familiar what could be inside of one those):
- dot matrix display: not enough resolution especially compared with the nice bold starburst characters of the previous models
- configurable screen: nice I guess but … for what? You said you like to full screen display… Can you see anything? Again when they use the small character sets for the small display compartments I have a really hard time reading
- ascent rate: wow, that’s really bad!!! The ascent rate uses the smallest characters on the bottom middle of the screen and when you exceed the 130% it flashes an inverse video message on the whole middle of the screen but the letters are still waaaay small
- size: bigger is better right? … well, not in my opinion. I dare anybody to measure the characters on this HUGE screen and on the previous model screen.
- position on the hand: the human hand can’t twist like that to square off the LCD screen with your eyes. The older model – being smaller – could be positioned a little bit offsetted on your wrist/forearm, this new one being so big has to be flat on your wrist

Don’t get me wrong, I think it is a nice computer and probably the decompression algorythm (I do a lot of decompression diving) is better but I really think they could have done better considering it is double – or more the money you would pay for the previous model.
