Input:
We bought this GPS unit for my brother for Christmas. My only experience with GPS units was as a science camp counselor last summer, but we were using much simpler units with the children. I chose this GPS because of the mapping features and the base map already loaded in the system. I looked through a lot of reviews of different systems and this seemed to be the best for what we wanted to use it for and the price we were willing to spend.

We have used the GPS a few times for fun around our yard and at some local county parks. Also, we tried it in the car when we drove to a family party. Thus far it has worked out very well. Once you get used to navigating through the pages, it is very easy to use.

For the price, this seemed to be the best buy for people like us who are just getting into the "game". Although we haven't used it for any serious excursions, it is really interesting to play around with the features as you hike and/or drive somewhere. My brother hopes to try out some geocaching near his university and also plans to play around with the GPS when he hikes in the Adirondack Mountains.

Although we don't know too much about other systems available, we are definitely pleased with the purchase.
