The GP37 is an advanced GPS navigator designed for coastal ships, fishing boats and pleasure craft. It is equipped with a WAAS and a DGPS receiver. The powerful processor performs high-speed processing, position fixing and augmentation. It utilizes both WAAS and differential radio beacon correction methods.

This compact and cost-effective unit offers extremely accurate position fixes -- 10 meters for the basic GPS, 3 meters where WAAS service is available and 5 meters with DGPS. 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 Speedometer Mode. The Steering Display mode provides an intuitive indication of course to steer and crosstrack-error (XTE). The Customizable display allows you to select the display layout so the navigation data you are interested in is displayed in large characters.
