As Kevin says, the feature sets are pretty compatible. One significant
difference is the usability, the Clearnav can be mastered in a few minutes

using the 4 page mostly pictorial reference guide, rather than a 68 page
manual.

The matching CNv vario system is equally usable, and an outstanding
multi-sensor vario.

Software updates are easily installed from web downloads; there have
been 2 factory hardware update in 6 years, the original optional upgrade
from 1/4 VGA to full VGA, and now the high speed processor plus even
higher brightness/lower power display.

The feature set of LX9000 is years ahead of ClearNav. I used to fly with ClearNav and I switched to LX9000. I would never switch back to ClearNav for many reasons, the feature set being the most important. I got tired of waiting for simple changes. Anyone who wants to know more about LX9000 please download the LX Styler and play with it to see the power of LX9000. You can make it as complicated as you like or as simple as you like. It is a very flexible platform.

The variometers are very similar in terms of performance. I flew with both of them concurrently.

Credits to ClearNav; extremely good support probably the best out of all manufacturers. The area task optimizer is quite good as well.

I looked seriously at LX Navigation computers before buying the LX9000 but a couple of years ago they had many problems. Their variometer was just upgraded and there is no real experience with it yet. On the other hand LX Navigation will work with CNv and C302 which is awesome. Kudos to LX Navigation for not trying to lock a user to one type of variometer. Their computer is also very configurable so maybe worth looking at.
