GPSMAP 188/188C Sounder

The GPSMAP 188 Sounder installs easily in open cockpit and overhead boxes, and features a quick map redraw using a high-speed RISC processor. This unit combines chartplotter and sounder capabilities in one unit, with split-screen capability so you can view your position and sounder information at the same time. Detailed marine cartography is presented on a high-resolution (240 x 360 pixels), 10-level grayscale, liquid crystal display.

With a built-in worldwide basemap, the GPSMAP 188 Sounder will be fully compatible with GARMIN's new BlueChart™ marine cartography and many MapSource™ CD-ROM products. The unit is designed to provide precise GPS positioning using correction data obtained from the Wide Area Augmentation System (WAAS). This product will provide position accuracy to less than three meters when receiving WAAS corrections. The GPSMAP 188 Sounder also accepts RTCM-104 differential corrections.
