Rating: Great instrument for its price
Reviewer: David Patterson Attn:DP3579,
I bought it for my trip to DR and made 6 dives with it.
DG02 has a nice, readable display and delivers all info you need during your dive. The log is also handy and readable. The 2 weaknesses are backlight and audible alarms. The first, I found out is hard to switch on, the second is to low. Both issues came during fresh water cave dive. While ascending in a steep and narrow chimney, exhausted air made enough noise to obscure an alarm sound and I could not turn the backlight on time to see VARI. And these are the reasons why DG02 is 4.5* piece of technology.
