Are compasses impacted by metal buildings and various RF type signals?
From the ground it looked like it was off 5 degrees or so. But once up on top, it seemed very close and tweaked it a degree or so. Back on ground and it seems I went the wrong way from what it looks like on the ground.
Is this a task that requires two folks? Seems like the needle was clearly skewed up top, internet antenna signals?? "True North" walked on me various times.
