content: I purchased this to product so that I could find my way on a 600 acre piece of property for hunting. I found it to be very helpful and was even able to mark good areas I found while scouting and find them again in the predawn darkness. The auto-tracking feature was really cool and I now have a map of all the major trails on the property. I'm not a tech guy, and wish I had someone to help me figure out how to use all the features. But just by playing with it I was able to figure out most of the main features. I hope to do some geocacheing in the future, if I can figure it out.
