The Review
The X1 is toted as the iPhone of dive computers. Wow! What a great computer. Super clear display, easy learning curve, and loaded with great features.

I spent about 30 minutes with the X1 getting to know it before I took it for a dive. The dive siumlator function is excellent and very useful for getting a feel of how it will behave under water. My first dive with the unit went like clockwork.

The X1 ships as a bare unit, and firmware needs to be purchased and installed before it will function. I chose vPlanner Live ($145), since I use vPlanner for all of my dive planning. Installation of the firmware went without a hitch, and I was up and running within the hour.

Pros
•Great display. Super clear and bright.
•You get to choose which firmware/deco software to run
•Easy computer interface via USB Connection to download logs and update firmware.
•Support for the X1 and V-Planner live available on Liquivision Forums
•V-Planner Live and the X1 firmware is updated often
•Integrated electronic compass (not perfect, but it works)
•PPO2 monitor available soon (Dec 2008) which monitors up to 3 O2 sensors (and CO2 when available)
•Long lasting rechargeable battery can last weeks without charging.

Cons
•Wristband is kinda lame. I dove mine with the Deep Sea Supply Bungee wrist mount.
•Battery is sealed inside and must be sent to the factory for replacement.
•Tapping feature can lead to false taps if set too sensitive, or too hard to tap if set too stiff.
•A small passthrough for a bungee "leash" would be nice in case strap fails.

Conclusion
The Liquivision has performed flawlessly for me, and the simple interface made the transition a snap.. The combination of a great hardware platform with a great implementation of V-Planner on a dive computer is a superb match.. I have been diving the X1 as my primary computer since the day I got it.
