I bought this new GPS for my wife specifically for geocaching. First impressions were good, nice design, size just right for my wifes smaller hand and the interface was good similar to my own Montana. You can load pretty well any number of caches in compressed gpz format. So all good so far. Unfortunately, in operation it was a different story even with a small number of caches loaded it took a long long time to find satellite's and be ready to use. Also when looking for caches the accuracy left a lot to be desired my Montana showing to be on one side of a duel carriageway and the 650 showing it on the other side about 40ft away. I have used GPS for many years for walking and caching and know how to change settings etc and satellite inaccuracies but could not get this machine do be useful. Therefore returned to Amazon. Disappointed.
