The Forerunner 955 with solar charging and a touchscreen, as well as the Forerunner 255 with a multi-GPS location for even more exact monitoring, were introduced by Garmin.
The Forerunner 255 is the less expensive and lighter of the two, making it a popular choice. It comes in two sizes: 46mm and 41mm
The L1 and L5 satellites are used in the multi-GPS band, which has been gaining popularity for the previous three years.
This aids precise tracking, particularly in challenging environments such as a canyon where the signal may bounce off a rock.
