(Model 280751 not shown)

The BUSHNELL TACTICAL binocular is designed for the military/law enforcement field, but is also ideal for any demanding environment or application where rock-solid durability is required. Featuring a liquid-filled compass built into the viewing optics (model 280750), compass swing stops immediately due to an advanced damping design. Bearings are called out in easy-to-read precise 1° increments, ideal for navigation and locating objects accurately. A range-finding scale allows the viewer to estimate the range to objects of a known size. The BUSHNELL TACTICAL is fully waterproof/ fogproof and shock protected with suregrip rubber armoring, and has roll- down eyecups for use with sunglasses and prescription eyeglasses. The optics feature fully multi-coated lenses for excellent light transmission. The BUSHNELL TACTICAL comes complete with rugged nylon case and neck strap. Built to last, it includes a lifetime limited warranty.

HOW TO USE

First, adjust the width (interpupillary distance) of your binoculars so that when you look through them, you see a single circular image. Then focus the binocular for one eye at a time by turning the oculars (eyepieces) until you see an equally sharp image with each eye. If more than one person will be using the binoculars, you should mark the left and right eyepieces for your own vision to permit quick readjustment.

USING THE COMPASS

The compass is a precision unit. It has extremely fast damping so that there is almost no ‘swing’ and is corrected for dip (Latitude). The compass scale is in one degree increments and is aligned with the vertical range finding scale. When using the compass, always keep in mind the local variation between magnetic and true north.

Compass (Model 280750 ONLY)

ABOUT THE RETICLE

The vertical scale (reticle) visible through the right half of the binocular allows you to calculate distance to an object if you know its height, or to calculate the height of an object if you know its distance from you. Detailed instructions for using the reticle are provided in later pages of this manual.

USING THE COMPASS ILLUMINATOR

The BUSHNELL TACTICAL compass model (#280750) comes with a built-in LED compass illuminator for use at night and in low light conditions. The compass housing is located on the top right side of the binocular, with the two battery compartments (inc. one for a spare set) found on the front of the binocular, below the center hinge shaft. When the ambient light does not permit you

to see the compass heading clearly, press the green power button on the top compass housing. If the light is dim or does not come on, replace the batteries. If the light does not operate after replacing the batteries, please contact the Bushnell dealer nearest you.

HOW TO CHANGE THE BATTERIES

To change the batteries, use a thin coin to remove the battery compartment cover by turning it counter-clockwise. Remove the two batteries. The batteries have a (+) on

the front and a (-) on the back. Be sure to insert the new batteries with (+) signs in the same direction. Replace the battery cover by turning it clockwise. The two batteries

should be replaced at the same time. The batteries should be taken out if the binoculars will not be used for a long time. Batteries left in the binocular for prolonged periods of time without being used may leak and cause damage to the binocular.

Battery Type: Two LR44 1.5 volt alkaline button cell

or equivalent batteries: 1.5v alkaline A76 / G13 / 157

IMPORTANT

AFTER EXPOSURE TO SALTWATER OR SPRAY, FLUSH THE BINOCULARS THOROUGHLY WITH FRESH WATER AND WIPE DRY. AVOID EXTENDED EXPOSURE TO BRIGHT SUNLIGHT AND SEVERE TEMPERATURE FLUCTUATIONS. FOR EXAMPLE, IF THE BINOCULAR HAS BEEN USED UNDER VERY COLD CONDITIONS, BRINGING IT INTO A HEATED ENVIRONMENT COULD CAUSE CONDENSATION BUILD UP. ALLOW TIME FOR GRADUAL CHANGE IN TEMPERATURE.
