i walk my dogs 3-5 miles every day and took the gps with me just to get used to it and stuff. i notice that as i wear it around my neck, the back being rubberized and somewhat tacky, it tends to get flipped so its face side against my chest and not reading or registering the sattelites. anyone else have this issue? have you figured out a way to stop it? a small pocket on the shoulder of a pack or garment would work. or on top of my boonie maybe. any thoughts?
