I question GPS being wrong more then 50%.
I'm not sure what you mean? Where did this 50% figure come from and what is it in reference to. Can you say a bit more about this?
Never blindly follow the GPS. It's a tool, a good tool, but not an infallible one. I use mine everyday while out geocaching and it has gotten me into good trouble more often than not! <very big grin>
(More often then not) to me says that he’s saying it doesn’t work more times then it does, that has to be over 50% of the time. I question this statement.
