I purchased this Garmin (my first hand held GPS unit) for hiking and geo caching with the kids. I've never owned one before and don't have any comparisons against other hand held devices. With that being said,I'm quite happy with this unit. After downloading the TOPO maps, which is not cheap, this thing is great to use. I've gone hiking with it, and used the track back trail finder, have set way points during the hike and works just like it is supposed to.
There is a bit of a learning curve if you are unfamiliar with handheld GPS units, such as I am. It's not a steep curve, keep playing with it and search out YOUTUBE videos and tutorials and it gets easy to use.
I have also gone geo caching with the kids, and they love it, we have fun searching caches as a family.
