I have used both the tripod method and a on-the-ground angle iron flat mounting, and prefer the the ground method. I purchased the meter and found it to be more of a problem than a help. Now I just use the Meter screen on the set up page, once I have made the "course" adjustments. Then I make the "fine" with the meter pages. Takes about 20 minutes.
