RadarPlus® SM161R-2 Series Dual AIS Receivers

Shine Micro RadarPlus SM161R-2 Dual AIS Receivers


An Automatic Identification System, or AIS, is an indispensable tool for navigation and safety at sea. Information gathered by the SM161R-2 Dual AIS Receivers is more detailed than radar and enables the everyday boater to see what's coming long before it is in line of sight.

The rugged, industry standard SM161R-2 series incorporates dual stage RF input protection to provide superior protection against near lightning strikes and high power transmitters. In addition, with a receiver sensitivity of -113dbm the SM161R-2 is even better than it's predecessor, SL161R.

With the addition of the embedded 12 channel GPS receiver and the optional Enhanced Signal Analysis software, supplemental diagnostic functions become available such as:
