Get Your Bearings
In addition to multi-GNSS support, the GPSMAP 66 series provides ABC (altimeter, barometer, and compass) sensor capabilities to track your journey. The built-in altimeter provides elevation data to accurately monitor ascent and descent, while the barometer can be used to predict weather changes by showing short-term trends in air pressure. The three-axis electronic compass keeps your bearing whether you’re moving or not.
