Interpupillary adjustment
First adjust the binoculars so that both eyepieces are directly in front of your eyes, so that you can see one
single circular image.Note : the image will not be clear. You will adjust for clarity in the next step.

Focusing
This model has two individual diopter adjustment rings on each telescope so you can adjust the optics to your
individual eyes. After viewing an object through the binoculars, close your left eye and rotate the right diopter
adjustment ring until the object image appears sharp and clear in your right eye. Just do the same
manipulation for your left eye.
If you share your binoculars with another person, note the diopter index mark setting at the base of the
eyepiece
fi
rst (6). Then you can simply return the eyepiece to those settings when you next use the
binoculars to view an object at the same distance.

1.
What is View Angle
The view angle of an object is the angle from your binoculars to the edges of the object. It is calculated in
mils using the Mils Reticle on your binoculars.
Using this measurement you can calculate the distance to an object where the height or width of that object
is known.
This measurement is taken either horizontally or vertically and known as Horital View Angle or Vertical view
Angle.
