HOW OUR DIGITAL TECHNOLOGY WORKS

The Pro ₁M™ emits invisible, eye safe, infrared energy pulses. The Pro ₁M™ Advanced Digital microprocessor and ASIC chip (Application-Specific Integrated 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.

RANGING ACCURACY

The ranging accuracy of the Pro ₁M™ 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 ₁760 yards / ₁609 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. Red 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.

GETTING STARTED

OPERATIONAL SUMMARY
While looking through the Pro ₁M™, depress the power button once to activate the Vivid Display. Place the aiming circle (located in the center of the field of view) upon a target at least 5 yards away, depress and hold the power button down until the range reading is displayed near the bottom of the in-view 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 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 10 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. To re-fire, press the button down again.

ADJUSTING THE EYEPIECE
Your Pro ₁M™ is constructed with a twist-up eyepiece designed for comfort and to exclude extraneous light. For users without eyeglasses, rotate the eyecup counter clockwise while pulling up until it locks into the fully "up" position. The Pro ₁M™ provides extra-long eye-relief. If you wear glasses, make sure the eyecup is in the down position as this will bring your eye closer the eyepiece lens allowing you to see a full field of view. To lower the eyecup from the full "up" position, rotate clockwise while pushing down slightly. It is also possible to set the eyecup to positions "In between", fully up and full down, which may suit some individuals better. The Pro ₁M™ is also equipped with an adjustable eyepiece (+/- 2 Diopter Adjustment) that allows one to focus the VDT™ display relative to the image. Simply rotate the diopter setting until the VDT™ is in focus.

VIVID DISPLAY INDICATORS
Your Pro ₁M™ Vivid Display™ incorporates the following illuminated indicators:

1. PinSeeker™ Indicator
2. Aiming Reticle
3. Battery Life Indicator
4. Active Laser
5. Distance Displayed in Yards/Meters

BATTERY LIFE INDICATOR
Battery Indicator:
Full charge
2/3 battery life remaining
1/3 battery Life remaining
Battery Indicator Blinks - Battery needs to be replaced and unit will not be operable.

INSERTING THE BATTERY
Remove the Posi-Thread™ battery door by lifting the battery door tab and then rotating counter clockwise. Insert a (CR₁23) 3-volt lithium battery into the compartment negative end first, then replace battery cap.
Note: It is recommended that the battery be replaced at least once every 6 months.

ACTIVE LASER
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).

PINSEEKER^™
Ever have trouble getting distance to the flag? This advanced mode allows easy acquisition of the flag without inadvertently getting distances to background targets (i.e. trees) that have stronger signal strength.
For ease of use, the device will always be in PinSeeker^™ Mode.
To use, align the aiming circle reticle onto the flag that you want distance to. Next, press and hold the POWER button and move the laser slowly over the flag or desired object until a circle surrounds the flag indicator. If the laser beam recognized more than one object (i.e. flag and background trees), distance of the flag will be displayed and a circle will surround the PinSeeker™ indicator informing the user that distance to the flag (i.e. closer object) is being displayed in the VDT™ (as seen below). There may be times when only the laser beam only sees one object in its path. In this case, the distance will be displayed, but because more than one object was not acquired, a circle will not surround the flag indicator.
TIP: While pressing the POWER 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 closest of the objects recognized by the laser. Once the device has shut off, the unit will always default back to the last mode used.

PINSEEKER^™ WITH SLOPE +/-^™
This advanced patented mode will be found only on model 20-5₁08 (Pro™ ₁M Slope +/-™). Model 205₁08 features a built-in accelerometer-based inclinometer that digitally displays the exact slope angle from -20 to +20 degrees of elevation and is +/- ₁.0 degree accurate. The Slope +/-™ mode will automatically compute an angle compensated range based upon distance and slope angle determined by the laser rangefinder and built-in inclinometer. This data is then combined with internal algorithmic formulas dealing with average club use and ball trajectories. The angle compensated range provides direction on how to play the shot (i.e. add distance if an incline, subtract distance if a decline).

HOW TO USE SLOPE +/-^™
Once in this mode, you will see a "° " in the field of view informing you that you are in the Slope +/- Mode. Press the POWER button to obtain distance to the flag or other objects. Once the range is displayed, continue to hold the POWER button down for approximately 2 seconds while holding the aiming circle on the flag and keeping the unit as steady as possible so as to allow the inclinometer enough time to measure slope. Then release the POWER button. Once you have released the power button, a degree of angle and compensated range will be displayed beneath the standard distance as seen below.
In this example, the true distance is ₁62 yards, slope is +4 degrees, and the compensated range is ₁73 yards. The "" symbol means "Play-As", so instead of playing as ₁62 yards, "play-as" 173 yards.

THE ADVANTAGE OF SLOPE +/-^™
The distance to flag A in the drawing below is ₁62 yards. It is also ₁62 yards to flag B although it is on a slope. However, if you were to play this hole as ₁62 yards, the ball (X) would fall short of the hole/flag because you did not take slope into account.

THE TRUTH ABOUT SLOPES
Trying to determine slope angle with the naked eye can be rather deceiving. Most are not well versed to accurately determine slope angle. For example, most golf courses average slope is approximately 4 degrees. A large slope at a golf course is generally no more than 8 degrees. Of course this can vary, and that is why this device will measure slope from -20 to 20 degrees.
Some real world examples may help clarify. A moderate roof pitch is 6/₁2, which means that the roof rises six inches for every ₁2 inch horizontal distance. That equates to 26.5 degrees. You can scramble up this pitch when hanging Christmas lights, but climbing that slope for the distance of a good golf shot on a course would be exhausting. To retrieve a 200 yards shot, you would climb 300 feet up!
Golf Example: Let's say you are a strong golfer with a 300 yard shot. At a 20 degree slope the Pin would be 50 feet above you. In other words, you be driving the ball to the top of a 5 story building!!!
NOTE: For your convenience, the Slope +/-^™ Mode also contains the PinSeeker^® Mode/feature.

MENU SETUP

MENU SETUP DISPLAY BRIGHTNESS
Vivid Display Technology™ dramatically improves contrast, clarity and light transmission while increasing brightness of the digital readout, making distance readings legible in low light environments. There are four intensity settings to choose from and this is the first setting within the SETUP menu. Press the MODE button for 5 seconds to get into the SETUP menu. The existing brightness setting will be flashing (i.e. BRT₁, BRT2, BRT3, or BRT4), pressing the MODE button will toggle between the four brightness settings. "BRT₁" is the lowest intensity while "BRT4" is the brightest. Simply press the MODE button until the desired brightness setting is displayed and select by pressing and releasing the POWER button.

UNIT OF MEASURE OPTIONS
The Pro ₁M™can be used to measure distances in yards or meters. The unit of measure indicators are located in the lower right portion of the VDT™. There are two measuring settings to choose from and this is the second setting within the SETUP menu. Look through the eyepiece, depress the "MODE" button (left side of the eyepiece) and hold it down for approximately 5 seconds to get into the SETUP menu. Depressing the MODE button will toggle through the brightness settings. If you are changing from yards to meters, a change in unit of measure will be indicated by the illumination of the M for meter indicator while the Y for Yard indicator is turned off. If you are changing from meters to yards, the opposite will occur. The Pro ₁M™ will return to the last unit of measure setting used each time the unit is turned on.

ACCESSORY MOUNT
Molded into the bottom of the product is a threaded accessory mount that will allow you to attach the following Bushnell® Golf Accessories:
Golf Cart Mount: Attaches the rangefinder to your golf cart for easy access. Quick release clamp attaches to golf cart and can be easily removed afterwards.
Push/Pull Cart Monopod: Steady your hand with this telescoping monopod. Simply attach rangefinder to the monopod and insert into cart umbrella holder.
360R Retractor: Attaches the rangefinder to your golf bag for easy access while walking the course.

CLEANING
Gently blow away any dust or debris on the lenses (or use a soft lens brush). To remove dirt or fingerprints, clean with a soft cotton cloth, rubbing in a circular motion. Use of a coarse cloth or unnecessary rubbing may scratch the lens surface and eventually cause permanent damage. 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.

TROUBLE SHOOTING TABLE

If unit does not turn on VDT™ does not illuminate:

• Depress power button.
• Check and if necessary, replace battery. If unit does not respond to key presses, replace the battery with a good quality CR 1 23 3-volt Lithium battery.
• Ensure the display is on the brightest setting while in sunlight. While pressing Power Button, cover the objective lenses to determine if the display is on. See the display brightness setting instructions on Page 1 0.

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 good quality CR 1 23 3-volt Lithium battery.

If target range cannot be obtained

• Make sure VDT™ is illuminated.
• Make sure that the power button is being depressed.
• Make sure that nothing, such as your hand or finger, is blocking the objective lenses (lenses closest to the target) that emit and receive the laser pulses.
• Make sure unit is held steady while depressing power button.

NOTE: The last range reading does not need to be cleared before ranging another target. Simply aim at the new target using the VDT™'s reticle, depress the power button and hold until new range reading is displayed. Specifications, instructions, and the operation of these products are subject to change without notice.
