Frequently Asked Questions - MARINE BINOCULARS 137507 BUSHNELL

How to adjust the binoculars for a clear image?

First adjust the interpupillary distance by folding the central hinge until you see a single circular image. Then focus by turning the eyepieces one eye at a time until you get a sharp image for each eye. If multiple users share the binoculars, note the eyepiece graduations for quick adjustment.

How to use the built-in digital compass?

Press the rectangular button on the left side of the binoculars to turn on the compass. The compass displays the bearing in degrees of the direction pointed. The power automatically turns off after one minute to save battery. If the display does not light up, replace the batteries.

How to calibrate the digital compass?

After turning on the compass, perform a full rotation (360°) of the binoculars in the following order: pitch (vertical up/down rotation), yaw (horizontal left/right rotation), then roll (rotation around the central axis). Return to the starting position after each step. Calibration must be done outdoors, at least 2 meters from any metallic object.

What do the directional segments on the compass display mean?

The display shows 8 segments (N, NE, E, SE, S, SW, W, NW) that turn off based on the direction pointed. For example, if the compass indicates between 338° and 22°, the North segment becomes transparent, signaling you are facing north.

How to use the reticle to measure distance?

The vertical scale (reticle) is graduated in MIL (each division = 5 MIL). If you know the object's height (in meters), use the formula: Distance = (Height × 1000) / MIL value. If you know the distance, height = (Distance × MIL value) / 1000.

How to change the compass batteries?

Use a coin to turn the battery compartment cover counterclockwise until the "unlocked" icon aligns with the white dot. Remove the old battery and insert a new CR2 Lithium 3V battery respecting polarities (+ and -). Close by turning the cover until the "locked" icon.

What to do after exposure to saltwater?

Rinse the binoculars thoroughly with fresh water to remove salt and spray. Wipe and dry carefully. Avoid sudden temperature changes that can cause condensation.

What battery to use for the compass?

The compass requires a CR2 Lithium 3V battery. Make sure to respect polarities when inserting. Remove the battery if not used for a long time to avoid leaks.

What to do if the compass display does not light up?

Check that the battery is properly installed and not discharged. Replace it with a new CR2 battery. If the problem persists, perform a compass calibration after changing the battery.

What is the warranty on these binoculars?

Bushnell offers a limited lifetime warranty for the first owner, covering defects in materials and workmanship. To claim warranty, return the product postage paid with proof of purchase and $10 US for shipping and handling (for USA and Canada).

USER MANUAL MARINE BINOCULARS 137507 BUSHNELL

BUSHNELL MARINE porro prism binoculars are designed for the boating enthusiast in particular, but are also ideal for any demanding environment or application where rock-solid durability is required. The new model 137507 features a digital compass built into the viewing optics, with direction and bearing indicators tracking as you view. Bearings are called out in easy-to-read precise 1^ increments, ideal for navigation and locating objects accurately. The digital compass delivers reliable accuracy anywhere in the world (both Northern and Southern hemispheres). A range-finding scale allows the viewer to estimate the range to objects of a known size. The BUSHNELL MARINE 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 multi-coated lenses for excellent light transmission, along with a UV reducing lens coating and internal UV filter to prevent potentially harmful ultraviolet light (wavelengths below 400nm) from reaching your eyes. The BUSHNELL MARINE comes complete with rugged nylon case and neck strap. Built to last, with a lifetime limited warranty.

ADJUSTING THE BINOCULARS

First, adjust the width (interpupillary distance) of your binoculars with the central hinge, 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.

ABOUT THE DIGITAL COMPASS

The built-in compass is a precision unit with a digital display which indicates bearing in degrees, corresponding to the direction the binoculars are pointed, as well as the compass point heading. When using the compass, always keep in mind the local variation between magnetic and true north. To turn on the compass display, press the rectangular button on the top left side of the binocular.

ABOUT THE DIGITAL COMPASS

Power automatically turns off after one minute to prolong battery life. If the display does not come on, replace the batteries (see "How to Change the Batteries").

Before using the compass for the first time, it is necessary to calibrate the compass, using the following procedure:

COMPASS CALIBRATION PROCEDURE

This calibration procedure will ensure that the displayed readings are accurate for the area in which the compass will be used. The calibration should be done outdoors if possible, and with the binocular kept at least 7 feet away from any large metal objects. Facing due north is not required for calibration.

For best results, the compass should be calibrated again:

1) After any significant change in your location since the last calibration
2) After changing the battery, especially if a different brand is used
3) If the binocular was in direct contact with a large metal object (for example a steel table) while the power was on (note that the power automatically shuts off after one minute, so this should not be common)

TO CALIBRATE THE COMPASS: After turning on the compass by pressing the power button on the top right side of the binocular, rotate the entire binocular clockwise or counter-clockwise once in a full circle (360 degrees) along each of these three axes, in this order, returning to the starting position at the end of each step (see the diagrams on the following page):

Step 1: Pitch (rotate 1 full cycle "end over end", in a vertical plane up/down)
Step 2: Yaw (rotate 1 full cycle "spinning around", in a horizontal plane left/right)
Step 3: Roll (rotate 1 full cycle as shown along the binocular's center hinge axis)

CALIBRATING THE COMPASS

Step 1-Pitch

(rotate 1 full cycle "end over end", in a vertical plane up/down)

Step 2: Yaw

(rotate 1 full cycle "spinning around", in a horizontal plane left/right)

Step 3: Roll

(rotate 1 full cycle as shown along the binocular's center hinge axis)

READING THE COMPASS

After completing the last rotational cycle, the compass is calibrated, and will display "0" degrees when the binocular is pointing straight North (magnetic north), 180 degrees when pointed due South, etc. The chart below shows the range of degrees corresponding to each of the 8 segments in the circle to the left of the digital display, which represent common compass headings. For example, when the compass indicates anywhere from 338 to 22 degrees, the North segment will "switch off" (become clear) indicating that the binocular is pointed in a northerly direction.

Direction	Deg. Range	Direction	Deg. Range
N (360/0°)	338°~22°	S (180°)	158°~202°
NE (45°)	23°~67°	SW (225°)	203°~247°
E (90°)	68°~112°	W (270°)	248°~292°
SE (135°)	113°~157°	NW (315°)	293°~337°

HOW TO USE THE RETICLE

The vertical scale (reticle) visible through the left half of the binocular, above the compass display, 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. Each mark on the vertical scale has a value of 5 MIL (1 Mil is equivalent to an angle that can determine an object one meter in height at a distance of 1000 meters). Therefore, if a navigation chart gives the height of an object, by sighting on it and counting the number of MILs, you can determine how far away it is. Here are the two formulas (note use of metric units):

1) To measure distance when the height is known:
Object height (m) x 1000 m = Distance in meters Scale Reading
2) To measure object height when the distance is known:

HOW TO CHANGE THE BATTERIES

To change the battery, use a coin to remove the battery compartment cover by turning it counterclockwise, until the "unlocked" icon and white dot on the cover line up with the dot on the binocular. Set the cover aside and remove the battery. Note the "+" and "-" polarity markings on the battery. Be sure to insert the new battery correctly, in the same direction as shown on the sticker inside the battery compartment, with the "+" (positive) terminal going in first so it is at the bottom of the compartment, and the "-" negative end facing the battery cover. Replace the battery cover with the "unlocked" icon and two dots lined up again, then turn it (with fingers or a coin) until the "locked" icon lines up with the dot on the binocular. The battery 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. After replacing the battery, be sure to follow the calibration procedure for the digital compass.

Battery Requirement: One CR2 Lithium (3 volt)

IMPORTANT NOTE

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.
