The Fusion™ 1 Mile ARC™ emits invisible, eye safe, infrared energy pulses. The Fusion 1 Mile ARC‘s Advanced Digital microprocessor and ASIC chip (Application-SpecificIntegrated Circuit) results in instantaneous and accurate readings every time. Sophisticated digital technology instantaneously calculates distances by measuring the time it takes for each pulse to travel from the rangefinder, to the target, and back.


The ranging accuracy of the Fusion 1 Mile ARC is plus or minus one yard / meter under most circumstances. The maximum range of the instrument depends on the reflectivity of the target. The maximum distance for most objects is 1000 yards / 914 meters while for highly reflective objects the maximum is 1 mile / 1600 meters. Note: You will get both longer and shorter maximum distances depending on the reflective properties of the particular target and the environmental conditions at the time the distance of an object is being measured.

The color, surface finish, size and shape of the target all affect reflectivity and range. The brighter the color, the longer the range. White is highly reflective, for example, and allows longer ranges than the color black, which is the least reflective color. A shiny finish provides more range than a dull one. A small target is more difficult to range than a larger target. The angle to the target also has an effect. Shooting to a target at a 90 degree angle (where the target surface is perpendicular to the flight path of the emitted energy pulses) provides good range while a steep angle on the other hand, provides limited ranging. In addition, lighting conditions (e.g. the amount of sunlight) will affect the ranging capabilities of the unit. The less light (e.g. overcast skies) the farther the unit’s maximum range will be. Conversely, very sunny days will decrease the unit’s maximum range.




The battery compartment is located between the objective barrels. Simply remove the battery cap by rotating it counter clockwise and insert a CR-1233-voltlithium battery into the compartment negative end first, then replace the battery cap.

NOTE: It is recommended that the battery be replaced at least once every 6 months.


Before you begin using your laser rangefinder binoculars, a few simple, one-timeadjustments should be made to ensure that you can get sharp focus of objects by just using the main focus knob on the binoculars. This process will compensate for any variations in the eyesight or vision of the individual user:

1.Leave the rubber eyecups in their “up” position if you are not wearing glasses, or twist them down if you are. Grasp the left and right sides of the binocular, and pull them apart or push them together while looking through the binocular to adjust the eyepiece spacing until your view is a single circular image.

2.While looking through the binoculars, press the power button to turn on the display. Look through just the right side of the binocular-youwill see a red aiming circle in the center. Point the binocular at a plain background.

3.Rotate the display focus (right eyecup) until the circular reticle appears as sharp as possible to your right eye. This compensates for any difference between your vision and the correct focus for the laser.

4.Next, continuing to look through the right side only, aim at a distant object (preferably one containing fine detail such as a tree or sign), and adjust the binocular’s center focusing knob until it appears as sharp as possible to your right eye.


5.Finally, view the same object through only the left side of the binocular, and rotate the diopter adjustment (left eyecup) until it appears sharp to your left eye (do not touch the center focus knob while doing this). This compensates for any vision differences between your left and right eyes.

Once set, note the number on the left and right binocular tubes that the index mark on each eyecup is lined up with. With the display focus and diopter adjustment set to these positions, you should be able to obtain sharp viewing of objects at any distance by simply adjusting the center focus knob while you look through the binocular. There is no need to re-adjustthe display focus or diopter adjustment, unless you share the binocular with another user, or if your eyes become tired over a long period of use.


While looking through the binocular, depress the power button once to activate the Matrix Display. Place the aiming circle (located in the center of the field of view) upon a target at least 10 yards away, depress and hold the power button down until the range reading is displayed near the bottom of the in-viewdisplay. Crosshairs surrounding the aiming circle indicate that the laser is being transmitted. Once a range has been acquired, you can release the power button. The crosshairs surrounding the aiming circle will disappear once the power button has been released (i.e. the laser is no longer being transmitted). Note: Once activated, the display will remain active and display the last distance measurement for 3 seconds. You can depress the power button again at any time to distance to a new target. As with any laser device, it is not recommended to directly view the emissions for long periods of time with magnified lenses. The maximum time the laser is transmitted (fired) is 10 seconds. Tore-fire,press the button down again.

Angle Range Compensation

The Fusion 1 Mile ARC is an advanced premium laser rangefinder binocular featuring a built-inaccelerometer-basedinclinometer that digitally displays the exact angle from-90to +90 degrees of elevation and is +/- 1.0 degree accurate. The Bushnell® Fusion 1 Mile ARC™ solves a problem hunters have been faced with for years. The problem: Bow and rifle hunters have struggled with extreme uphill and downhill angles because of how these angles alter true horizontal distance to your target. The Solution: ARC’s integrated inclinometer provides elevation angle to allow for distance compensation when targeting objects that are either uphill or downhill. This data is then combined with internal algorithmic ballistic formulas.

ARC (Angle Range Compensation) Modes

Bow Mode (): Displays line of sight distance, degree of elevation, and true horizontal distance from10-99yards / meters and a maximum inclination of +/- 90°.

Rifle Mode (): Calculates and displays the amount of bullet drop, at the target in inches, centimeters, MOA or MIL. The amount of bullet drop is determined by the line of sight distance to the target, degree of elevation, along with the specific ballistic characteristics of the caliber and ammunition load. When you range your target, the line of sight, degree of elevation, andbullet-drop/holdoverin inches, centimeters, MOA or MIL will be displayed from 100 to 800 yards/meters with a maximum inclination of +/- 90°. One of eight ballistic groups (identified as A, B, C, D, E, F, G, and H) for center fire rifles and two ballistic groups (Identified as I and J) for Black Powder / Muzzleloaders can be selected by the user, with each formula representing a given combination of caliber and loads. The ballistic groups are selected by the user in theSET-UPmenu.

Regular Mode (ARC OFF): This mode does not provide any degree of elevation or compensated distance, but instead, line of sight distance only.

The Fusion 1 Mile ARC can be used to measure distances in yards or meters. The unit of measure indicators are located in the lower right portion of the Matrix Display.


Crosshairs surrounding the aiming circle indicate that the laser is being transmitted. Once a range has been acquired, you can release the power button. The crosshairs surrounding the circle will disappear once the power button has been released (i.e. the laser is no longer being transmitted).


The Fusion 1 Mile ARC was especially designed with hunters in mind. The selective targeting modes allow you to adjust the performance parameters of the unit to suit your specific situation and environment. To move from one mode to another, press the POWER button once to turn on the unit. While looking through the eyepiece, press the MODE button and quickly release. The different targeting modes available and mode indicators are listed below:
