Works as advertised
Received in good condition, pre-programmed with MMSI. Installation was easy and worked the first time powered on. Very satisfied with the quality and with the responsiveness of Milltech. The only issue with the ProAIS2 software going into an endless discover. Found out the FIRST time you connect and discover via USB the AIS unit should be powered off.

Installation was straight forward, and the units perform well. I did not have to use the optional interior external antenna, as the unit acquire GPS signal installed near the fiberglass cabin top.
