HOW TO USE
First, adjust the width (interpupillary distance) of your binoculars with the central
hinge, so that when you look through them, you see a single circular image. Then
focus the binocular for one eye at a time by turning the oculars (eyepieces) until you
see an equally sharp image with each eye. If more than one person will be using the
binoculars, you should mark the left and right eyepieces for your own vision to permit
quick readjustment.
USING THE COMPASS
The compass is a precision unit. It has extremely fast damping so
that there is almost no ‘swing’ and is corrected for dip (Latitude).
The compass scale is in one degree increments and is aligned
with the vertical range nding scale. When using the compass,
always keep in mind the local variation between magnetic and
true north.
HOW TO USE THE RETICLE
The vertical scale (reticle) visible through the left half of the binocular, above the
compass display, allows you to calculate distance to an object if you know its height, or
to calculate the height of an object if you know its distance from you.
