User Instructions

To help you get the best results from your equipment, please read the following instructions carefully.

Adjusting to obtain a single picture. To adjust the binoculars to match the spacing of your eyes simply rotate 
the two sides of the instrument around the center hinge until a single rounded picture is obtained when looking 
through both eyepieces.

Adjusting for maximum sharpness (focusing). Marine PSII binoculars feature individual eyepiece focusing but the 
large depth of field generated by the 7x50 specification means they deliver ‘in focus’ images from approximately 
50 yards to infinity distance. As a rule for general observation over 50 yards, the binoculars can be ‘set’ with the 
white vertical marks on the eyepiece tubes positioned directly above the rubber dots on the main body. 

Focusing at close range (below 50 yards) is facilitated by turning the left and right eyepieces simultaneously. 

Adjusting for differences in visual acuity. Some people have differences in strength or visual acuity between their 
eyes. To compensate for this the eyepiece tubes can be rotated to different positions (usually within a few degrees 
of each other) for any given distance.

Wearing glasses. Marine PSII binoculars deliver full field of view with or without glasses. To ensure the maximum 
available field of view is obtained, the fold down rubber eyecups fitted to each eyepiece housing should be in the 
‘down’ position when viewing with glasses. Be sure to return the eyecups to the ‘up’ position if you or anybody 
else wants to view without glasses.
