I bought one on 4/24/09. Was delivered yesterday 4/27/09. Although I saw a few reviews where people stated that it arrived in obviously used or non-functional condition, mine appears just fine and seems to work great (at least on land). The quality appears to be nicer than I expected, buttons and bezel move nicely, display is pretty easy to read. If you'd like to see the manual for it, there's one available online (I can't seem to post the link, but you can [GOOGLE]NG705seriesMANUAL[/GOOGLE]).
Selected Features:
Switches to dive mode automatically at about 5'.
Displays current and max depth, current water temp, elapsed dive time.
Status indicator flashes if descending faster than 10m/minute.
Beeps if ascending faster than 6m/minute.
Has an auto-backlight function that can be toggled on/off.
Logs 10 dives, storing date & time started, elapsed time, max depth, lowest temp.
After 10 minutes of surface time, logs dive, or if re-enter in under 10 mins, counts as same dive.
Selectable for meters or feet, Celsius or Fahrenheit, sea or lake.
Can erase dive logs.
Also has a stopwatch and 3 separate countdown timer functions.
So far, I'm considering it to be $60 well spent and will happily wear it on my wrist as a backup to the computer.
