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 7×50 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 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 a 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. 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.
-
Gently remove excess dirt and dust using compressed air or a lens cleaning brush.
Caution: Hard and persistent rubbing of dirty surfaces can cause abrasive scratches on the surface of the glass which may distort viewing. -
Breathe on the 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 binoculars. If you have any problems or damage
the instrument in any way our Service Department is on hand to help you.
