Editorial Reviews:
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 and comes factory equipped with a WAAS and a DGPS receiver as standard supply. You'll receive the most accurate position fix available when utilizing both WAAS and differential radio beacon correction methods.The GP37 boasts extremely accurate and repeatable 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 currently 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. If the DGPS signal can not be received for any reason, the unit will automatically switch to the WAAS signal. Of course, you can manually set the reception mode as well.The GP37 features several display modes, including a Plotter, two Customizable displays, Steering, Highway and Speedometer Modes. Like the GP32 you may enter waypoints as lat/lon, Loran-C or Decca LOPs with up to a 12 character name. The track plotter has 14 range scales from .02 to 320 NM with a memory of 1000 track points. In addition, 950 waypoints can be permanently stored for easy recall. 50 routes with up to 30 waypoints each.
