The eTrex 10/20/30 series is an update to one of the most popular bikepacking GPS units, the eTrex VistaHCx, featuring a faster chipset and totally redesigned software. Major new features of interest to bikepackers are the track manager (much easier uploading of routes), custom raster maps and new track following software. In general the unit is easier to use and runs faster than the older VistaHCx line.
