The GPSMAP 188C Sounder can be easily installed 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. For the GPSMAP 188C Sounder, the display is a high-resolution (234 x 320 pixels), 16-color TFT display.
Featuring a built-in worldwide base map, the GPSMAP 188C Sounder is fully compatible with Garmin's new BlueChart marine cartography and many MapSource CD-ROM products, including Fishing Hot Spots.
