I recently bought this watch and took it for a dive today and it was very good. It keeps track of starting time of dive, curent/max depth, bottom time(in analog and digital), current/lowest temperature, max depth/bottom time/fast ascent audible alarm with LED visual alert and measures surface interval too! It is also capable of storing up to 20 dives. The best feature of this watch in my opinion is that it is solar powered thus it doesn't need battery replacement and not to mention the cost savings of having it pressure checked. I can think of only 2 setbacks... the water sensor is so sensitive that if your finger comes into contact with it, it activates dive mode which in turn does not allow u to access the other watch functions. The next setback is the small LCD display but it shouldn't be an issue to most divers as this watch should only be used as a back up equipment and NOT as a primary source. If you are willing to spend AUD$700 on it(which could get you a dedicated wrist top nitrox dive computer for the same price), i highly recommend it...absolutely!
