SI-TEX SAS-300 AIS Class B Transceiver w/External GPS Antenna

The SI-TEX SAS-300 AIS Class B Transceiver with External GPS Antenna is a professional-grade vessel tracking and safety device built for serious boaters who demand situational awareness on the water. This Class B AIS transceiver broadcasts your vessel's position, course, and speed to nearby ships, fishing vessels, and commercial traffic while simultaneously receiving and displaying targets from their transmissions on a compatible chartplotter or display.

The SAS-300 integrates a dedicated external GPS antenna for precise position fixes independent of your main chartplotter, ensuring your AIS broadcast remains accurate even if primary navigation systems fail or require recalibration. The Class B designation means this unit operates at lower power output than Class A commercial transceivers, making it ideal for recreational and small commercial vessels under 300 tons while still providing reliable target reception and transmission at sea.

The compact form factor allows flexible installation in cabin spaces, making it suitable for various vessel types. Whether you're navigating busy shipping lanes or operating in regions with high commercial traffic density, the SAS-300 enhances maritime safety and collision avoidance.
