    Re: Calibrating a Bris sextant

    Yes, I made an artifical horizon with a mirror and two high precision levels, and get pretty good results with that.  My land based attempts with the Bris is just to get the theory and calcs under my belt. I will make it to the coast at some point to use the sea horizon. I just don't want to bake in the hot summer sun on the beach right now.
