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

The SI-TEX SAS-300 AIS Class B AIS Transceiver with Internal GPS Antenna is a professional-grade marine navigation system designed for vessel operators requiring reliable automatic identification system (AIS) monitoring and GPS positioning. This compact transceiver integrates dual functionality—transmitting your vessel's location and receiving real-time AIS target data from nearby maritime traffic—into a single integrated unit suitable for fishing vessels, commercial operations, and recreational boaters who prioritize situational awareness on the water.

The 6.5-inch high-resolution color TFT display delivers 740 x 480 pixel clarity, enabling you to monitor AIS targets on a standard radar-style presentation against worldwide base charts or—with an optional SD card—overlaid on full C-MAP MAX cartography for enhanced navigational context. Advanced Rmax™ technology maximizes both receive and transmit range while ensuring all available AIS messages are decoded in real time, critical for identifying commercial traffic, fishing vessels, and navigation hazards in congested waterways or open ocean environments. The internal GPS antenna eliminates external mounting complexity while maintaining position accuracy essential for collision avoidance and regulatory compliance.

This Class B transceiver addresses the needs of vessel operators who require AIS functionality without the cost of Class A equipment, making it ideal for commercial fishing operations, charter services, cargo vessels, and serious cruising sailboats. The combination of integrated GPS, real-time target tracking, and flexible display options makes the SAS-300 a practical solution for mariners who need to monitor vessel traffic patterns, verify transponder coverage, and maintain navigational situational awareness in shipping lanes and coastal regions.
