Similar
in styling and function to the GPSMAP 292C/298C Sounder,
the GPSMAP 398C Sounder along with its counterpart, the
GPSMAP 392C, add preloaded U.S. inland freshwater cartography
to its enhanced worldwide basemap information. The preloaded
inland maps offer 50-meter shoreline resolution throughout
the U.S., with even more detailed 10-meter resolution on
select lakes. Other details include depth contours, tide
and current data, boat ramps, mile markers, hazards, marinas,
campgrounds, area roads, and more. Both units accept preprogrammed
data cards and are compatible with the latest BlueChart®
g2 series marine cartography. The built-in 500-watt (RMS)
sounder on the GPSMAP 398C features Ultrascroll™ for
high-speed screen updates, and its Garmin CANet™ bus
allows sounder display information to be shared with another
chartplotter onboard.
