Scubapro Galileo Sol
With its large dot matrix screen, it sits comfortably on your arm and is easy to read. You can change the configuration of the screen (3 different options) to show exactly what you would prefer it to show!
It uses the Scubapro PMG (Predictive Multi Gas) ZHL8 ADT MB algorithm that allows you to use up to three nitrox mixes (21-100%) and will show you what the optimum time is to switch gases. It can calculate deep (intermediate) stops during your ascent and you can change the microbubble levels, to make the computer more conservative with age or your physical condition.
You can add wireless air integration to it with a transmitter and with the heart rate monitor, the computer can sense your effort and incorporate that in your no deco calculations. Add to that the full digital compass with bearing memory to help you find your way underwater and you've got one of the best and most popular dive computers out there!
Additional features: oil-filled technology, max depth: 330m, dive logbook up to 100 hours, optional trimix and apnea upgrade and user changeable battery.
Optional upgrades: Transmitter and USB PC interface!
