Though less effective, and with possible shorter range, mirror flashes can also be
seen on cloudy days with limited visibility. Procedures for using the mirror are as
a. Hold the mirror in a manner which will allow the sunlight to reflect on a
nearby surface such as the hand or other close object.
b. Bring the mirror up to eye level and using one eye, look through the sighting
device until an intense bright spot is located. This is the aim indicator.
c. Hold the mirror close to the eye and slowly turn it until the bright spot is on
the target (fig. 2-6).
