Some very interesting results from using my new itrek m3 gps... I left it on when I went in some stores. I was surprised to find it had a perfect fix the whole time I walked around walmart(!) I could have set a waypoint for the electronics department and I could clearly see from the gps tracks where the aisles were.
The gps is able to keep a fix but the accuracy is not nearly as good when walking around other buildings like target. They must put more materials into their construction.
I was surprised to see how good the receivers have gotten. It's definitely a good sign.
