The Shoot From 2 Ends screen is used to provide more accurate
vertical closure to a traverse. The routine requires that a foresight
point is shot, but it is not stored until after it is occupied and another
shot is taken to the previous occupy point. The coordinates for the
foresight point are computed from an average of data gathered at
each occupy point.

shortcut to the Surveying and Repetition
Settings screens (Page R-32 and R-35
respectively).
Foresight : is the name given to the next stored
point.

set.
