Title: Mark or average?
Post by: Fishingoat on February 24, 2015, 12:41:59 PM: I was reading the journal post and it got me thinking about my gps waypoints. I mark a waypoint but wonder what others do and if anyone ever marked a hole and averaged a hole to compare which is more accurate when they came back at a later date. I do realize accuracy does change day to day but wondered if anyone ever compared. My cousin was a Lawrence pro-staffer a few years back and he always averaged saying it was better because it used more satellites. I think average uses 4 and mark uses 3. Not sure so do not quote me on that. I think a good test would be to mark a visible spot and average a visible spot and come back at a later date and see which is closer. Might try it and post results later. Thoughts?

I marked a hole, imbedded an orange ribbon in the ice next to it, and came back a week later and it put me within a foot. Also I found an abandoned bridge on Nimi that I GPS'D the 4 corners on last year. Even after transferring the data to my new phone, it still put me within a couple feet and easy enough to find with my vex and gas auger. It might not be 100% to the inch but will definitely get you close enough to find it really fast with electronics.
