For sale is an Argo Navis handset with encoders and mounting hardware to suit a 10" Meade Lightbridge.
No user manual disk or fitting instructions are included but these can be downloaded from the Wildcard Innovations website. The mount cradle for the handset is not included having been lost.
In the likely event you have another mount type you can almost certainly purchase a suitable kit from Wildcard Innovations. Check here:

There is no mains-to-DC adapter for power input, this unit having been run from batteries, but these are easy to find.
$300, and I can post it anywhere. Contact me for a quote if you are not in Australia.
Cheers
