Topcon XT Survey grade GNSS receiver for base or RTK. GPS primary.
Comes with Getac PDA with Topcon Topsurv 8 for acquisition. As per photos. While not up to the job for major survey activity, it would be more than suitable as a Base Station, RTK via NTRIP or a survey student. The green tape is only there to stop the power being plugged into this connector as it has the same pin config as the data port. This was a design flaw later rectified.
