    100:1 clarifacation
    From: Doug Royer

    Mr. Pisko,thanks for your help and thoughts on this method.I am going to
    start using this method,because of the ease, exclusively instead of the
    angle and ref. dist. method I was using.Useing either the 100:1(10 mil) or
    10:1 (100 mil) ratio will work just fine.I did the field experiment to prove
    or disprove to myself,only,that this system will work.I have proved to
    myself that it does indeed.As long as my math was correct I am satisfied.I
    am not looking for that great of an accuracy in field
    measurements.Approximations in the field will be fine.The reason I went to
    all the trouble of measureing the angular distance as accuratly as I could
    was to assure myself that the method can be as accurate as needed.In the
    field paces etc. will suffice.
    The math is as you wrote it in your responce of 04-05 is what I was trying
    to convey.As long as my method of calculating the distance is correct the
    experiment was correct.
    The Bussol compass has 6,000 at North marked in 2 mil increments and number
    marked every 5 increments on the outside edge of the card and 0 to 360* on
    the inside.It is twice the diam. of the Cammenga and has very good lens.It
    also has a nifty attachment that I beleve measures inclination or
    elevation,as it was an arty compass,but I have no documentation for it.
    It sounds like you are familiar with artillery theory.Were you trained in
    it?I am becoming fascinated by it and have ordered some manuals.If you would
    like to discuss this subject off list I would like to learn.
