Distance Scale
The scale allows you to measure either the distance
of an object if the height is known, or the height of an
object if the distance is known.
The unit ‘mil’ is used on the scale. One scale
division is 5 mils and equivalent to an object of height
5m being viewed at a distance of 1000m.
To calculate either the distance or height of an object:
Distance [m] = Height[m] x1000 / No. of mils
Height [m] = Distance[m] x no. of mils / 1000
Compass
The Marine-2 is fitted with a ø30mm graduated compass
in degrees suitable for use in the northern hemisphere.
N =360º, S =180º, E=90º and W=270º.
To use, simply hold the binoculars in the viewing
position [horizontal] and focus on an object.

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-2 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
zero marks on the eyepiece tubes positioned directly above the vertical line marks on the main body.
Focusing at close range (below 50 yards) is facilitated by turning the left and right eyepieces simultaneously
anticlockwise.
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-2 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.
User Instructions
Care and cleaning. Marine-2 binoculars require little maintenance but occasionally the outside surfaces of the
eyepieces and objective lenses will need cleaning. To avoid damaging these surfaces please read the following
carefully.
(i) Gently remove excess dirt and dust using a compressed air device or blower brush. Caution: Hard and persistent
rubbing of dirty surfaces can cause abrasive scratches on the surface of the glass which may distort viewing.
(ii) Breathe on exposed glass surface and then wipe with an optical cleaning cloth (code 30277) in a circular
motion until the surface is clean again.
Do not attempt to dismantle the instrument as this will invalidate the guarantee.
WARNING. Never under any circumstances use a binocular to view the sun. Doing so will cause serious damage
to your eyes.
We hope you will get a great deal of pleasure from your new Opticron binocular. If you have any problems or
damage the instrument in any way our Service Department is on hand to help you.
