I'm happy with my purchase, before I had a Garmin eTrex I think the first generation, the external appearance was identical with the antenna was against less powerful, I could lose the signal during a walk with forest path. With eTrex H, the signal very well. This GPS is very convenient, coupled with IGN map with GPS tracks, it's a real pleasure to hike. There are many possibilities, I invite you to browse the CD to learn more about this product.
