The biggest reason to buy is its combination of a Class B transceiver with a 5 Watt output and built-in GPS functionality, which provides improved vessel visibility and position reporting without requiring a separate transmitter. It is a practical upgrade for sailors and powerboat owners who already use NMEA 2000 chartplotters and want a simple, professional AIS solution.\u003c\/p\u003e\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eClass B Transceiver:\u003c\/strong\u003e Provides both reception and secure 5 Watt transmission to make the vessel visible to nearby ships and shore stations, improving situational awareness.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNMEA 2000 Connectivity:\u003c\/strong\u003e Integrates directly into existing NMEA 2000 networks so AIS targets and alerts appear on compatible chartplotters and multi-function displays.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInternal GPS:\u003c\/strong\u003e Includes an internal GPS receiver so the unit reports accurate position data without needing a separate GPS source, though an antenna is required for best reception.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompact Installation:\u003c\/strong\u003e The modest form factor and marine-focused design make it straightforward to install in tight instrument spaces aboard small yachts and dayboats.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e5 Watt Output:\u003c\/strong\u003e Delivers enhanced transmission power compared with 2 Watt Class B devices, extending the range at which the vessel can be seen by others.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eWho It's For\u003c\/h2\u003e\n\u003cp\u003eThe AIS 800 is aimed at recreational boaters and small commercial operators who already run a NMEA 2000 backbone and want reliable AIS position reporting and reception.
