NT-921 MKII AUTOPILOT

The Navitron NT921 MKII is an advanced digital autopilot system designed for workboats, fishing vessels, pilot boats, and research vessels. Its microprocessor-based architecture, user-friendly interface, and automatic deck sensitivity are key features. NMEA or magnetic heading inputs and a built-in radio navigator interface provide track steering and waypoint guidance without interference. Additionally, three heading outputs for radar stabilization and tracking provide high integration capabilities.
