    Re: Horizontal Angle and the Hand Bearing Compass
    From: Greg Rudzinski

    Herbert,

    You are right. A pair of magnetic bearings won't check deviation. A third bearing and second horizontal angle is required. The intersection of the two horizontal angle circles is the true position to compare with the three bearings for the deviation check.

    Greg Rudzinski


    "This sounds like magic. The arc of position will always contain the
    intersection point of the two magnetic bearings. How can it serve as a
    check on deviation?"
    Herbert Prinz
