The Garmin eTrex H is the size of a cell phone for me to use as a bike-and Fußwanderer ideal.Einfach, receiving strong and long Akkulaufzeit.Mich interested for a long time in my wanderings, how many kilometers am I so moved, normal step Count round bicycle speedometers are too inaccurate, this device shows me pretty much my migrated or worn kilometers on, really great. Who can do without a displayed map, for it is the right device, anyone who wants more must dig deeper into their pocket, a bike mount can be ordered, will be displayed: time, trip distance, time in motion, maximum speed and can Gesamtkilometer.Man Mark also tours etc, this is personally not a concern for me, so all I can give you any information.
