I use this for rec. diving with nitrox. Functions very well. However when diving at low temperatures such as 4 degrees celcius. It will show low battery even with good battery. Alarms could be louder. Hard to hear with wet suit hood on. Very acurate and good easy to use computer.
This Dive computer offers a good value for your money (in my opinion) It is really easy to read underwater thanks to it's large display. My main concern is that the two button navigation often makes it tedious programming the various functions
