So went to Ocotillo Wells(so cal desert) this Easter Weekend. I set up a GPS Easter Egg Hunt for the kids in our camp. I did the same thing as I usually do when on rides. Mark location, name it and hit OK. Then when setting up the first group to find their teem egg, the compass arrow was pointing a complete oposite direction. What the heck could I have done wrong? Again, I use it on rides and never had that kind of problem. I get within a few feet of the Marked spot. On the egg hunt, not even close. FYI Very clear day not a cloud in the sky.
