Email from Beat:
To all DistoX customers:

ATTENTION:
There seems to be a problem with a newer version of the Disto X310.
These new version includes a changed Laser Module which will NOT work with
the actual DistoX2 board.
The attached picture shows the two variants:
Upper device: Old version with large Laser module.
Lower device: New version with small Laser module.

The serial number (on the box and in the battery compartment) seems to
start with 0 for old and with 1 for new devices, but this is not confirmed
yet.

I will search for a solution for the new device as soon as possible.

Regards

Beat
