Jon, I've been studying the literature for the headland method. It isn't clear to me if a guy can hit the start headland button and then set the A-B on the first pass around and then complete the headland on the third pass as you approach the A-B that you set on the first and before you get to the first guided swath done off the A-B.

I take it that the lightbar gives you guidance off the first headland pass as you make the second & in this case the third along the north edge??
