X1 or XEO?

The X1 is Liquivisions "Expedition Grade" trimix dive computer. It has an extremely rugged aluminum housing, electronic compass, and 2 pressure sensors for redundancy. It has an integrated rechargeable lithium battery. It offers two software packages (VPM and Bühlmann), sold and downloaded separately. The X1 is best suited to the advanced technical diver.

The Xeo is a more approachable "entry level" technical computer - it is well suited to the diver who is just entering the technical or rebreather realm. It has a resilient plastic housing, but we recommend the ZAGG shield to prevent scratches. It has one pressure sensor. It has user-changeable batteries. It comes with software pre-loaded. The Xeo is more accessible to a nitrox and beginning trimix diver.

The Liquivision X1 was the only dive computer out of seven different computers to survive a 283m dive without resetting or going into gauge mode.
