I have had an original etrex for the last 15 years, which I normally use for fellwalking and geocaching, exchanging information with OS digital mapping on my pc. It cost £130, and the only weakness was poor sattelite reception under tree canopy and cliff face shadow. I have now bought an etrex H, and taken them both out together. The H performs a lot better in areas of poor reception, with an average accuracy twice as good as the old etrex in areas of poor reception. (eg:15ft against the old units 30ft) It even holds a signal when carried in a coat pocket, where the original one isn't useable, warning of poor gps signal. I am very impressed and satisfied with the H, and as a bonus, it only cost £65.
