Garmin GPSMAP 238 Sounder    

The dual frequency 238 Sounder combines chartplotter and sounder capabilities in one unit which installs easily in open cockpit and overhead boxes.

With a built-in worldwide basemap, the GPSMAP 238 Sounder will accept data cards programmed with GARMIN BlueChart marine cartography or data from most MapSourceT CD-ROM products.

GPSMAP 238 Sounder is designed to provide precise GPS positioning using correction data obtained from the Wide Area Augmentation System (WAAS). GPSMAP 238 Sounder will provide position accuracy to less than three meters when receiving WAAS corrections and also accepts RTCM-104 differential corrections.
