The eTrex 22x and 32x handheld devices come preloaded with road-routable TopoActive maps that feature streets and trails so you can take the journey off the grid. Now you can know your surroundings — such as waterways, natural features, buildings, and more. The eTrex series uses both GPS and GLONASS satellite systems so the receiver has the ability to track in more challenging environments than GPS alone. eTrex 32x adds a 3-axis compass and barometric altimeter, making it easy for you to keep your bearings.
