I have been aware of C-probe. I think the SensBox is a much better
way to go, since it also has:

Integrated super sensitive GPS

BT4 LE making it very easy to connect to device and available to ubiquitous and
easy to use OSX devices and apps

And even more devices and apps with announcement that Android will adopt BT4 LE


Virtually unlimited flight recording in IGC format with security

Has display so it can be used as backup navigation

Has speaker so it can be used as backup variometer

CE and FCC approval

Splash proof soon to be waterproof

I have asked the makers of the C-Probe for any material that they
have but have not received an answer yet. As soon as I do I will publish it.
