I have the gpsmap 62s and been using it for caches and hiking i had old software on it and with the waas settings turned on and it jumped me all over the map.
after i updated the software the waas setting turned on made me accurate up to 9 feet or less.
with that said i didn't re-upload my maps so all my roads were off for some reason i updated it today and they seem back to how they were.
i set a way point standing next to object in a open field when i got home i entered it on google earth and it placed me with in a foot of were i was standing thats really good with the setting off it made me up to five feet from were i really was standing that is still pretty good if i say so. try doing that on a phone haha. next thing you know your up to 100 meters from were you really were standing
