Furuno GP37

The new GP37 DGPS/WAAS Navigator is compact in size, yet big on power, features and performance. This waterproof unit is perfect for a wide range of boats. It is equipped with a WAAS and a DGPS receiver as standard supply. It utilizes both WAAS and differential radio beacon correction methods to give you the most accurate position fix available. The GP37 offers extremely accurate position fixes -- 10m for basic GPS, 5m or better with DGPS and 3m or better where WAAS service is available. It should be noted that DGPS is more reliable and accurate, as the WAAS system is still currently under development. There is no guarantee of accuracy, integrity, continuity or availability of the WAAS signal. For that reason, the GP37 runs with DGPS as the default setting in auto selection mode. In this mode, if the DGPS signal can not be received for any reason, the WAAS mode is automatically selected. Manual setting is also available. The display modes include Plotter, two Customizable displays, Steering, Highway and SpeedMinimize
