LASER RANGEFINDER OWNER’S GUIDE
Model #: LP1800AD

Thank you for purchasing your new Bushnell® PrimeTM 1800 Laser Rangefinder.
This manual will help you optimize your viewing experience by explaining how to utilize the rangefinder’s features and how to care for it. Read the instructions carefully before using your rangefinder.

WARNING: As with any laser device, do not directly view the emissions for long periods with magnified lenses.

INTRODUCTION

Your Bushnell® PrimeTM 1800 is an ultra-compact, premium laser rangefinder with the latest Digital Technology, providing precise range readings from 5-1800 yards/5-1646 meters. Measuring 1.3 x 4.2 x 2.9 inches, the 6-ounce PrimeTM 1800 delivers high-speed target acquisition, with +/- 1 yard accuracy to the maximum range. The PrimeTM 1800 laser rangefinder features Bushnell’s patented ARCTM (Angle Range Compensation with Ballistics Intelligence), a new Ranging Engine for faster, more consistent response and readings, an ACTIVSYNCTM LCD with higher light transmission and water-resistant (IPX4) construction along with EXOTM Barrier Coating on the optics.

*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 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 affects. 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 a good range. In contrast, a steep angle, on the other hand, provides limited ranging. Also, 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. Conversely, very sunny days will decrease the unit’s maximum range.

HOW OUR DIGITAL TECHNOLOGY WORKS

The PrimeTM 1800 laser rangefinder emits invisible, eye-safe, infrared energy pulses. The PrimeTM 1800 rangefinder’s FPGA 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.

BATTERY ACTIVATION / BATTERY LIFE INDICATOR

Before first use: Remove the battery compartment cover by lifting the battery cover tab and then rotating the cover counter-clockwise. Remove and discard the red plastic disc covering the positive battery terminal, then replace the battery cover.
NOTE: It is recommended that the CR2 3-volt lithium battery be replaced at least once every 12 months. Please insert the negative end of the battery into the compartment first.

BASIC OPERATION

• While looking through the laser rangefinder, press and release the Power/Fire button to activate the display.
• If the display appears blurry, rotate the monocular eyepiece in either direction until the display is sharp for your vision.
• Placing the aiming circle (located in the center of the display) on a target at least 5-6 yards away, depress and hold the Fire button down until the range reading displays below the aiming circle.
• Once a range is acquired, you can release the Fire button. The four “crosshairs” just outside the aiming circle will go out, indicating the laser is no longer transmitting. The display will remain on and display the last distance measurement for about 15 seconds until the display automatically switches off to extend battery life.
• You can press the Fire button again at any time to check the range to a new target. To re-fire, press the button again.
• To scan the laser across an area and get continuously updated range readings, continue to hold the Fire button down and sweep the rangefinder over multiple targets. The crosshairs outside the aiming circle will flash to indicate scan operation.

TARGETING MODES

The PrimeTM 1800 laser rangefinder operates in three targeting modes, with Standard mode as the default. To select a different targeting mode, press the Mode button briefly until the desired indicator (BullsEye or Brush) appears. To return to Standard mode, press Mode one more time after the Brush mode indicator is seen. The targeting modes are:

• Standard Mode with Automatic SCAN (LCD Indicator ­ none) This setting allows most targets to range up to 1800 yards. They are used for moderately reflective targets that are typical of most distancing situations. The minimum distance in the standard model is 5 yards. To use the Automatic SCAN feature, press and hold the Fire button, then move the rangefinder from object to object while keeping the Fire button depressed. Automatic SCAN will allow the range to be continuously updated as multiple objects are targeted. Crosshair lines flash while scanning.

• BullsEyeTM Mode with Automatic SCAN (LCD Indicator (6) ) This advanced mode allows easy acquisition of small targets and games without inadvertently getting distances to background targets that have stronger signal strength. When more than one object is acquired, only the distance of the closest object will be displayed.
  With the rangefinder in BullsEye mode, align the aiming circle onto the object (i.e., deer) that you want to find the distance. Next, press and hold the Fire button and move the Aiming Circle slowly over the deer. If the laser beam recognized more than one object (deer and background trees), the distance of the closer object (deer) is displayed in the LCD.

• BrushTM Mode with Automatic SCAN (LCD Indicator (7) ): This advanced mode allows objects such as brush and tree branches to be ignored so that distance only to background objects are displayed. When more than one object is acquired, only the distance of the farthest object will is displayed on the LCD.
  With the rangefinder in Brush mode, align the aiming circle onto the object that you want to find the distance. Next, press and hold the Fire button and move the Aiming Circle slowly over the object. If the laser beam recognized more than one object (closeup tree branch and a deer in the background), a further object (deer) would be displayed.
  TIP: While pressing the Fire button, you can move the device slowly from object to object and intentionally force the laser to hit multiple objects to ensure that you are only displaying the furthest of the objects recognized by the laser. Once the device has shut off, the unit will always default back to the last targeting mode.

ANGLE RANGE COMPENSATION (ARC)

The PrimeTM 1800 Laser Rangefinder with ARCTM is specially designed with hunters in mind. Your PrimeTM 1800 rangefinder features a built-in inclinometer that solves a problem hunters have had for years. Bow and rifle hunters have struggled with extreme uphill and downhill angles because these angles alter true horizontal distance to your target. The ARCTM solution: an integrated inclinometer provides angular data to a processor chip when targeting either uphill or downhill objects. This data is combined with internal algorithmic formulas. The user-selectable ARC modes allow you to adjust the performance parameters of the unit to suit your specific situation and environment.
Along with the standard “line of sight” distance, the Fire button will display the true horizontal distance in Bow Mode-see the ARC MODES section. In Rifle Mode, display bullet-drop/holdover near the bottom of the display (14), along with the angle of the incline in degrees (indicated at the left side of the display (16)). For example, a bowhunter in a tree stand may aim at a downhill deer at a -52o relative to his position. The line of sight distance is 32 yards, but he is likely to “overshoot” the target based on that. The THD distance (compensated for the angle) reads 23 yards. That is the distance the hunter should use to base his shot.

USING THE SETUP MENU

The Setup Menu is used to select various options, such as the ARC Mode (Bow, Rifle, etc.) and distance units (Yards or Meters) of your preference. After powering on the unit, enter the Setup Menu and by holding the Mode button down until “SETUP” appears in the display (15). You will remain in the Setup Menu until you change or confirm all possible settings (varies depending on selected ARC mode), and “SETUP” is no longer displayed. Once in the Setup Menu, press the Mode button to scroll through or toggle the available items. Press the Fire button to confirm and save the currently displayed option/setting.
The first item you can select from the Setup Menu is the ARC Mode. Press the Mode button until the icon for the mode you want is displayed. Press the Fire button to confirm and continue selecting other related options/settings. More details regarding the various ARC modes are in the next section.

ARC (Angle Range Compensation) Modes

• REGULAR Mode ( ): This mode does not provide any degree of elevation or compensated distance information (no secondary display (14), only the line of sight distance (8). Select this mode (press the Fire button with “rE9” displayed while in Setup) for general purpose use or not use the rangefinder for bow or rifle hunting applications. After confirming your selection of Regular mode, the only other item in the Setup Menu is the Unit of Measure option (13). Pressing the Mode button will toggle the Units from the default “Y” (yards) to “M” (meters). Press the Fire button to confirm your
  selection (leave units set to Yards or change it to Meters) and exit the Setup Menu, returning to normal operation.

• BOW Mode ( ): Calculates and displays the degree of incline, and the resulting true horizontal distance in yards or meters, in addition to the line of sight distance. Select this mode (press the Fire button with the bow icon (1) displayed while in Setup) for bowhunting or other use if you don’t need bullet-drop/holdover information. After confirming your selection of Bow mode, the only other item in the Setup Menu is the Unit of Measure option (13). Pressing the Mode button will toggle the Units from the default “Y” (yards) to “M” (meters). Press the Fire button to confirm your selection (leave units set to Yards or change it to metric) and exit the Setup Menu, returning to normal operation.
  Bow Mode Example
  The true horizontal distance is shown near the bottom of the display (14), alternating with the tilt angle in degrees. For example, a bowhunter in a tree stand may aim at a downhill deer at a -52o angle relative to his position. The line of sight distance is 32 yards, but he is likely to “overshoot” the target based on that. The THD distance (compensated for the angle) reads 23 yards. That is the distance the hunter should use to base his shot.
  The line of sight is 32 yards, the angle is -52 degrees, and the Angle Range Compensated distance is 23 yards. Instead of shooting as 32 yards, shoot as 23 yards. If you were to shoot as if 32 yards, you would shoot over the top of the deer because of the severe angle.
  

If in BOW mode, the line of sight distance will display in the primary numeric display, and the inclination and horizontal distance will display in the secondary numeric displays. Bushnell® determined through extensive testing and interviews with high-profile bow hunting experts that multiple bow ballistic groups were not necessary. Bowhunters want to know true horizontal distance because that is how they practice shooting. Once they confidently know that, they can make any necessary adjustments–giving the bow-hunter anything else other than horizontal distance creates additional confusion and uncertainty.

Many people mistakenly believe that uphill shots perform differently from downhill shots because of gravity. However, it is not due to gravity but more of an aberration of the sighting system used on bows. The sighting pin on a bow resides several inches above the mechanical axis of the arrow. For example, when aiming 23 degrees up an incline, the arrow is at a different angle.

• RIFLE Mode(s) ( ): Calculates and displays the amount of bullet drop at the target in inches, centimeters, Mils, or MOA. The amount of bullet drop is determined by the line of sight distance to the target, degree of elevation, along the specific ballistic characteristics of the caliber and ammunition load. When you range your target, the line of sight, degree of elevation, and bullet-drop/holdover in inches, centimeters, Mils, or MOA will be displayed from 100 to 800 yards/meters with a maximum inclination of +/- 70°.
  One of eight ballistic groups (identified as A, B, C, D, E, F, G, and H) for centerfire 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 user selects the ballistic groups via the Setup menu. After entering the Setup menu (by holding the Mode button for a few seconds), briefly press the Mode button until you see the blinking Rifle icon (2), along with the letter for the ballistic group for your preferred ammo (or load).

Knowing Which Ballistic Group To Select
Bushnell engineers have researched currently available ballistic data and grouped many of the most popular calibers and loads into eight ballistic groups (A, B, C, D, E, F, G, H). Once you know what caliber and load you are shooting, look through the chart to determine which one of the eight ballistic groups matches your particular load and caliber. For Muzzleloaders, we have worked with PowerBelt Bullets to incorporate ballistic data into two ballistic groups (I and J). Below are a few of the most popular caliber/load combinations. A complete list of 2000 caliber and load combinations is on Bushnell’s website (www.bushnell.com).

Popular Caliber & Load Combinations

After you have determined which ballistic group corresponds to your caliber and load, select this ballistic group letter along with Rifle mode. The internal formula will determine the amount of bullet drop/holdover in inches or centimeters based on your caliber and load’s distance, angle, and ballistics.

What if my caliber/load is not listed?
While we have taken great care to include as many calibers and brand names in our ballistics tables, new loads are always developing. Also, some shooters load their ammunition with unique ballistic characteristics. If you cannot find your load in our ballistic tables, you can still use the laser rangefinder bullet drop feature. As above, sight in your rifle at 100 yds. Then shoot the rifle, without adjusting the riflescope, at 300 yds. Measure the bullet drop from the point of aim. Using this drop, select the ballistic group from below. If you are shooting long distances, you may want to check the bullet drop at 500 yds. Because there is enormous variation in rifle barrels, chambers, and hand loads, you should thoroughly test the ballistic setting before actual hunting. You may need to move up or down one group depending upon your tests.

After you have confirmed your selection of Rifle mode with the ballistic group you need (by pressing the Fire button while it appears in the display), the next item is the Unit of Measure option (13). Pressing the Mode button will toggle the Units from the default “Y” (yards) to “M” (meters). Press the Fire button to confirm your selection (leave units set to Yards or change it to metric).

Next, you will see “SD,” meaning Sight-In Distance. Briefly pressing the Mode button will cycle through a choice of 100, 150, 200, or 300 yards. Press the Fire button to confirm and save the setting when your preferred sight-in distance is displayed.

Lastly, you will have a choice of formats for the bullet drop/holdover data that will appear in the secondary numeric display (14): IN (inches), ML (Mils), or MOA (moa). Briefly press the Mode switch to cycle through the three options, pressing the Fire button to confirm and save the setting when your preferred bullet drop format is displayed. Note: if the unit of measure is set to Meters (M), the bullet drop is calculated and displayed in CM (centimeters) rather than inches.

Rifle Mode Example
The line of sight is 376 yards, the angle is -33 degrees, and the bullet- drop/holdover is 28 inches. ARC takes into account ballistic data based on your caliber and load from distances of 100-800 yards and compensates for any uphill and downhill angles that also affect bullet-drop.

The Prime™ 1800 rangefinder’s state-of-the-art digital technology allows the hunter or shooter to know precisely where to hold for an effective shot. This information is a helpful guide or tool, and in no way should it ever replace practice and familiarity with your rifle, cartridge, and load. We encourage practice shooting at different ranges, so you know how your rifle, cartridge, and load will perform under various conditions. Always know what is behind your bullet; if you don’t know, don’t take the shot.

• Reticle Select: The Setup menu allows you to select your preferred reticle type for the center of the display (for all modes). Press and hold the Mode button to get into the Menu screen. Tap Mode while in Reticle Select and cycle through Circle, Dot, and Circle with Dot (this is the default) options. Press the Fire button to confirm the selection of the reticle you prefer, and exit the Setup menu.
• ACTIVESYNCTM Brightness Setting: ACTIVESYNC is always on, allowing the display to adjust the display contrast to the background automatically. The Setup menu allows you to select your brightness preference (for all modes). Press and hold the Mode button to get into the Menu screen. Tap Mode to while in ACTIVESYNC and cycle through Brightness 25% (default setting), Brightness 50%, Brightness 75%, and Brightness 100% options. Press the Fire button to confirm the selection of Brightness you prefer, and exit the Setup menu.
  

CLEANING AND GENERAL CARE

The lenses of your Bushnell PrimeTM 1800 laser rangefinder are fully multi- coated for the highest light transmission. As with any multi-coated optics, take special care in cleaning the lenses. Follow these tips for proper lens cleaning:

• Blow away any dust or debris on the lens (or use a soft lens brush).
• To remove dirt or fingerprints, clean with the supplied microfiber cloth rubbing in a circular motion. Use of coarse cloth or unnecessary rubbing may scratch the lens surface and eventually cause permanent damage. The included washable microfiber cleaning cloth is ideal for the routine cleaning of your optics. Breathe lightly on the lens to provide a slight amount of moisture, then gently rub the lens with the microfiber cloth.
• For a more thorough cleaning, photographic lens tissue and photographic-type lens cleaning fluid or isopropyl alcohol may be used. Always apply the fluid to the cleaning cloth ­ never directly on the lens.

All exterior lens surfaces have our new EXO BarrierTM coating (in addition to full multi-coating). EXO Barrier, quite simply, is the best protective lens coating technology Bushnell has ever developed. Added at the end of the coating process, EXO Barrier molecularly bonds to the lens and fills the microscopic pores in the glass. The result is an ultra-slick coating that repels water, oil, fog, dust, and debris – rain, snow, fingerprints, and dirt will not stick. EXO Barrier is built to last: the bonded coating will not fade with the passage of time or normal wear and tear.

The rangefinder is manufactured and tested to withstand water exposure up to IPX4 standards. It is water-resistant but should not be submerged.

TROUBLESHOOTING

Never disassemble your laser rangefinder. Irreparable damage can result from unauthorized service attempts, which also void the warranty.

If the unit does not turn on, the display does not illuminate:

• Depress Power/Fire button.
• Check and, if necessary, replace the battery. If the unit does not respond to button presses, replace the battery with a good quality CR2 3-volt Lithium battery.

If unit powers down (display goes blank when attempting to power the laser):

• The battery is either weak or low quality. Replace the battery with a new 3 -volt lithium battery (CR2).

If the target range cannot be obtained:

• Make sure the display is illuminated.
• Make sure that the Power/Fire button is being depressed.
• Ensure nothing, such as your hand or finger, blocks the lenses at the front of the rangefinder that emits and receives the laser pulses.
• Make sure the unit is steady while depressing the Power/Fire button.
  NOTE: The last range reading does not need to be cleared before ranging another target. Aim at the new target using the display reticle, depress the power button, and hold until new range reading is displayed.
