GS520 Off Course Alarm

The GS520 Off Course Alarm is designed to give you peace of mind while you're out at sea. It keeps a close eye on your ship’s magnetic heading and lets you know right away if you start drifting from your intended course. With its easy-to-read digital display, you can always see exactly where you're headed. It also talks to other onboard systems using the NMEA0183 standard, so your heading information can be shared seamlessly across your navigation setup. Built tough for real conditions at sea, the GS520 isn’t just about alarms—it’s about giving you confidence that your vessel is pointed in the right direction, every step of the way.
