Your reasoning sounds good to me.I'll give it a try in the next couple of
days and report back if it works or not.I never thought of doing it that
way.But that is why this list is so good.New ideas.I use a Cammenga lensatic
compass with mil and degree gradiants and use the mil more than degrees but
thought most people are more familiar with degrees.I went with that for the
explaination.

The 1911 Encyclopedia mentioned yesterday for telegraph
cables wrote about a similar system double sighting system
under "rangefinder".  There was mention of a 50 yard cord
for a base line, two people, and two sextants held
horixontally.  One was fixed at 45 degrees, and the other
read the angle ... which I think may have had a special
spiral scale on a micrometer drum so as to read directly in
yards.  To bad the encyclopedia on line doesn't show
illustrations to match the descriptions.

One apparent problem was making sure both observers merged
the same target object with the split image of the other
observer's sextant.

However, I thought you mentioned a military compass, which
is graduated in mils in the US.  Could you not just take a
bearing, walk away from that point so as to keep the object
more or less at right angles to your (perhaps slightly
curved) path, and stop when the new bearing is 10 mils
different from your first?  That way, the distance to the
object will be 100 times the distance you traveled ...
barring local magnetic anomalies.

Just a thought.
