What are the differences between the GPSMAP 76C/CS series and the GPSMAP 60 series?
A. Garmin uses the letter “C” to signify units with color displays and “S” (for “sensors”) as a designation for units with a barometric altimeter and electronic compass. Units in the 76 series with a color display have 115 megabytes of mapping memory, and units in the 60 series have 56 megabytes of memory. Due to their larger memory capacity, 76-series units with a color display have a larger basemap than 60-series units. The 60-series units do not have tide prediction capability, while color 76-series units do. One other difference to note is that 76-series units will float, while 60-series units will not.
