    1911 encyclopedia
    From: Doug Royer

    Mr. Pisko, I have 1 thing to ask and 1 to report.It concerns the 1911 piece
    you wrote. I don't understand "one was fixed at 45* and the other read the
    angle".Could you expain this?I can't visualise what the 1st sextant is for.
    I went and tried what you suggested about the hand held compass this
    morning.I lased a phone pole and set up at 400 yds. distance.I then took a
    mil reading from the compass and keeping the compass and pole in constant
    sight walked,no measured distance just paces, untill there was a  mil
    bearing change around 10 mils.I did this multiple times and came up with
    differant distances each time.One of the readings was 424 paces.The 2nd was
    388 paces.The 3rd attempt was 409 paces.Not a very scientific experiment I
    agree but a good 1st approximation.I think this will method will work.I will
    have to work on the proceedure to find where I'm making my mistakes to get
    consistant results over many differant ranges.If this does work I won't have
    to carry a calculator when I go into the field.Thanks for the idea on this
    matter.When I was a grunt they taught us route step and I beleave each step
    was to be around 30 inches.Someone would be tasked with counting steps and
    keeping track of time and azimuth during the march and when asked give the
    sergeant the info to help with positioning.Marine Corp dead reckoning I
    guess.
