Bushnell Pro 1600 - Laser Rangefinder Manual

INTRODUCTION

The Pro™ 1600 is a precision Laser Rangefinding optical instrument designed to provide many years of enjoyment. This booklet will help you achieve optimum performance by explaining its adjustments and features as well as how to care for this precise laser rangefinding optical instrument. To ensure optimal performance and longevity, please read these instructions before using your Pro^™ 1600.

Your Bushnell® Pro™ 1600 is an advanced premium laser rangefinder comprised of Digital Technology allowing range readings from 5-1600 yards / 5-1463meters. Measuring 1.7 x 5.1 x 3.7 inches, the 12-ounce Pro™ 1600 delivers superb and accurate range performance to +/- one yard. The Pro™ 1600 features Selective Targeting™ Modes, Superb Optical Quality, 100% Waterproof Construction, and Bushnell's RainGuard® HD coating.

HOW OUR DIGITAL TECHNOLOGY WORKS

The Pro™ 1600 emits invisible, eye safe, infrared energy pulses. The Pro™ 1600's 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™ 1600 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 1600 yards / 1463 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

INSERTING THE BATTERY
First slide the door toward outside. The hinged door can now be opened. Insert one 9-volt alkaline battery into the slot as indicated, then close the battery door and slide until it locks in to place. The battery slot was designed to only accept the battery in the correct position. Therefore, if you are not able to close the batter door, check to ensure that the battery has been installed correctly.
NOTE: Use only high quality alkaline batteries. Do not use heavy duty or lithium batteries. It is recommended that the battery be replaced at least once every 12 months.
Low Battery Indicator: If the Y (Yards) or M (Meters) indicator blinks continuously or "loB" is displayed within the In-view readout, the battery charge is getting low and the 9-volt alkaline battery should be replaced.

ADJUSTING THE EYEPIECE
Your Pro™ 1600 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™ 1600 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™ 1600 is also equipped with an adjustable eyepiece (+/- 2 Diopter Adjustment) that allows one to focus the LCD display relative to the image. Simply rotate the diopter setting until the LCD is in focus.

OPERATIONAL SUMMARY

While looking through the 7x eyepiece, depress the power button once to activate the in-view Liquid Crystal Display (LCD). 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 Pro™ 1600's LCD will remain active and display the last distance measurement for 30 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.

LIQUID CRYSTAL DISPLAY (LCD) INDICATORS

Your Pro™ 1600's LCD incorporates illuminated indicators that advise the user unit of measure, when the laser is actively firing, when a target has been acquired, and targeting modes. A summary of these features is presented below:

UNIT OF MEASURE OPTIONS

The Pro™ 1600 can be used to measure distances in yards or meters. The unit of measure indicators are located in the lower right portion of the LCD. To select between yards and meters, quickly press and release the POWER button to turn on the unit (on top of the unit), look through the eyepiece, depress the "MODE" button (left side of the eyepiece) and hold it down for approximately 5 seconds. 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™ 1600 will return to the last unit of measure setting used each time the unit is turned on.

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).

SELECTIVE TARGETING™ MODES

The Pro™ 1600 was especially designed with golfers 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:
PinSeeker (LCD Indicator - ) 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.
Once in this mode, press the POWER button to turn the unit on. Next, 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 LCD (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 +/-™ (LCD Indicator - º) This advanced mode will be found only on model 20-5106 (Pro™ 1600 with Slope +/-™). Model 20-5106 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. If at any time you prefer not to use the Slope +/-™ Mode, simply press the MODE button to get to PinSeeker® or Standard with Automatic SCAN Mode.^™
Standard with Automatic SCAN: This setting allows most targets to be distanced up to 1600 yards. Used for moderately reflective targets that are typical of most distancing situations. The minimum distance in the standard mode is 5 yards. To use the Automatic SCAN feature, simply hold down on the POWER button for approximately 3 seconds and SCAN the rangefinder from object to object while leaving the POWER button depressed. Automatic SCAN will allow the range and display to be continuously updated very rapidly as multiple objects are targeted.

OPTICAL DESIGN

Magnification and Coatings
The Pro™ 1600 features a powerful 7x magnification monocular for viewing your target. Optics are Fully MultiCoated allowing maximum light transmission for optimum brightness, superb resolution and contrast for a clear vivid image even in low light conditions such as dusk or dawn. A liquid crystal display (LCD) is mounted within the optical system and when activated, displays a reticle for targeting, yards / meters, and Mode indicators. Inherent in the manufacturing process are small black spots that appear in the optical system. These are a natural characteristic of the LCD and cannot be fully eliminated in the manufacturing process. They do not affect the distancing performance of the unit.

RainGuard® HD
The outer surfaces of the objective and eyepiece lenses are RainGuard® HD coated. RainGuard® HD is Bushnell's permanent, patented, hydrophobic (water repellant) lens coating that prevents fogging by causing condensation from rain, sleet, snow or even your own breath to bead up into much smaller droplets than on standard coatings. Smaller uniform droplets scatter less light which results in a clearer, brighter view.

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.
