GPSMAP 557 allows for easy visibility, day or night. Whether it is flat, flush or swivel-mounted, it will be the focal point of your helm. It includes our hallmark user-friendly interface as well as Australia/New Zealand offshore mapping.
With the integration of a 10Hz GPS/GLONASS receiver, the 557 refreshes position and heading up to 10 times per second. It displays constant and fluid on-screen location and proves to be incredibly accurate when marking and navigating to any one of 5,000 user-created waypoints.
It also has Wi-Fi connectivity, giving you the opportunity to connect and access marine-specific apps via smartphone or tablet.
