4.1.3 Adjusting for image quality and clarity. 

  Unlike  some  binoculars  that  have  a  center 

focus  to  make  adjustments  this  binocular  has 

individual focusing adjustments. In order for you 

to adjust the optics to your individual eyes, you 

will need to adjust each eyepiece or ocular. After 

placing the binocular at your eyes, you will need 

to close your left eye. With your right eye open, 

you  will  need  to  take  the  fingers  in  your  right 

hand and adjust the ocular until you see a per-

fectly clear image of the target you are looking 

at. Lower the binocular and remember the diopter 

setting for the right eye . Now closing your right 

eye, repeat the process you used for the right eye 

and  turn  the  left  diopter  until  you  have  a  per-

fectly clear image. Again, take note of the diopter 

setting for the left eye. If, for some reason, the 

diopter settings are moved, such as letting some 

other person use the binocular, you will be able to 

quickly use (with out adjustments) the binocular 

again by setting the right and left oculars to their 

correct diopter settings for your eyes.

4.2 How to use the reticle measure azimuth 
4.2.1 What is azimuth

The    following   is the basic  definition of Azi-

muth. Azimuth   of   a   body is the arc of the hori-

zon intercepted between the north or south point 

and the foot of the vertical circle passing through
