Have had my Etrex 2 years now.Works great for keeping track of prairie dog towns.The trackback feature is great,lets you keep track of how fast you are going & how long to destination.Another use for it is a speedometer.The speedo on the oladys SSEI Bonnivile only went up to 115 but the Etrex clockt top speed at 158mph yehaw.
The only drawback I have found is that under a lot of tree cover it doesnt read consistantly & if you rely on it you are lost.Found this out the hard way last fall bear hunting in northern Mn.I have ben considering upgrading to the one with a built in compass=CJ
