The range of rangefinder is defined as follows

1. the measurement object has moderate reflectivity: Such as building walls.
2. the target reflection surface is perpendicular to the laser emission direction
3. the area of the reflector is not less than 2m*2m
4. the weather is clear but not in direct sunlight.

NOTE: It is recommended that you use a tripod to fix the rangefinder when measuring remote targets, so as to reduce the hitter of the machine in the process of measurement, and obtain better measurement results.

Measurement target

The rangefinder suitable for measuring high reflectivity object (such as street signs), medium reflectance object(such as a building wall), and low reflectivity object (such as trees and golf flagpole), When the reflectivity falls to a certain extent, the range decreases accordingly.

The factors that affect the measuring range, measuring speed and measuring accuracy:

1. Reflectance of object: For example, high reflectivity object at 1500 meters can be measured, but medium reflectance object can be measured at about 1000 meters. low reflectance object can be measured at about 700 meters only. (for diffuse reflection objects, such as water, it may not be measured)
2. Object shape: when the reflector area of the measured object is too small or uneven, measuring capability will be reduced accordingly. Such as trees, flagpoles, etc.
3. Measuring angle: when the laser angle is illuminated vertically on the reflecting surface of the measuring object, measuring capability is better, otherwise the measuring capability will be reduced. It is not guaranteed to achieve the measuring capability when measuring with measuring angles as manual advised.
4. Measuring environment: the measuring capability will be reduced under strong sunshine, the concentration of water vapor and suspended particulate matter in the air. For example rain, fog, snow, fog and haze weather.

NOTE: This model can enter the ramp correction mode for golf flagpole locking when measuring the flagpole with complex background and small area in golf. The golf flagpole locks the effective distance at around 250Y.

OPERATION INSTRUCTION

START UP

The rangefinder has two buttons: power on / measurement button "" and mode / unit switch button "". After recharged, press the button "" briefly to turn on the instrument. The instrument enters the distance measurement mode by default, and the display interface is as follows:

ADJUST THE FOCUS

The range finder is designed with an adjustable eyepiece (dioptre). By adjusting the focusing dioptre within a -5 to +5 range, people with far-sighted vision can use laser range finder without glasses. Looking through the eyepiece, turn the dioptre left or right until the view is focused with clarity to suit you

UNIT SWITCHING

Press and hold button "" for a long time, and the distance unit will switch between M and Y. And unit will be displayed as memory mode, i.e. the unit will be displayed as the unit in the last shutdown state.

MEASUREMENT MODE SELECTION

Short press button "" to switch the distance measurement mode and the slope correction mode back and forth.
And unit also will be displayed as memory mode.

1. Distance measuring mode
   
   Short-time press power button " ", the bull's eye " " will be blinked as " ", finally the distance value will displayed. The display as shown in the below figure.
   

* In the distance measurement mode, long press "" and bull's eye will be blinked as " ", finally the distance value will displayed. The display as shown in the below figure.

In the distance measurement mode, long press " " and the bull's eye " " will flash " " the instrument will scan the measurement target (i.e. continuous measurement), and the measurement value will be displayed on the screen in real time.

2. Trajectory correction mode
   The display as shown in the below figure.
   

The slope correction mode is often used in golf, which is also known as golf flagstick locking mode.

For example:
When the slope is positive, the hitting distance is far
Distance: AB distance = AC distance, if according to the actual distance, the parabola of hitting is 1, because the slope is positive, the actual can only fly to point C. To reach point B, it is necessary to hit the ball according to the point spacing of the ramp correction distance AE, and the hitting parabola is 2.

When the slope is negative, the hitting distance should be close
Distance: AB point spacing = AC point spacing. If it is based on the actual distance, the hitting parabola is 1. Because the slope is negative, it can only fly to point C. if it is to reach point B, it is necessary to hit the ball according to the point spacing of the slope correction distance AE, and the hitting parabola is 2.

3. Ramp correction mode
   1. Align the target center"" with the measurement target, press the button " "briefly, and the target center flashes from "" to " " until the measurement value is obtained, as shown in the following figure.
      
   2. Long press the " " button, and conduct continuous measurement around the golf flagpole. When the instrument is locked to the flagpole, the instrument will vibrate instantaneously, prompting the user to get the measurement value. At the same time, the flagpole icon " " is displayed as " " and the display interface is as follows:
      

COMMON QUESTIONS AND ANSWERS

1. Is this range finder with slope adjustment function? And how to switch it from Y to M?
   A: Yes.it has. It's a range finder that measures distances from the location you are shooting from to the object your rangefinder locks onto. Wherever you want a distance measured it will give it to you and even includes a slope compensation measurement too if the linear distance has slope between the two points. And you could press " " for 2 seconds to switch the "Y" to "M".
2. How does this work in low light conditions? Dusk and dawn. Can you still see the readings?
   A: The range of this rangefinder is related to the nature of the target being measured, the angle between the beam and the target, and the visibility of the weather. Generally speaking, the smoother the target, the brighter the color, the larger the area, the more vertical the beam between the target surface, and the clearer of weather, the target is measured far, otherwise the closer. So we recommend that you could use it in a sunny day, its results would be more accurate.
3. What kind of battery does it use? Is it rechargeable via USB?
   A: This rangefinder is rechargeable, no battery needed. And it comes with a USB to type c charging cable. If there is no electricity to continue working, you just need to recharge it.
4. What I should do when I have some problems about the rangefinder? Or there are something lost in the package?
   A: Contact us directly. Any questions or problems, please feel free to contact us via email: service@tavool.com.

SAFETY

• Do not look directly at the laser beam when using the product.
• Do not aim from the laser holes or look at the optical system while pressing the power " " button to avoid damage to the eyes.

NOTE:

• Do not touch the lens surface with your fingers during use, otherwise the film on the lens surface will be damaged.
• This instrument is precisely adjusted by the instrument, please do not disassemble it at will
• When the exposed glass piece is contaminated, please wipe it gently with a lens velvet cloth. Do not wipe it with other objects to avoid damaging the surface layer of the optical glass.
• When carrying or using, avoid collision or heavy pressure, and do not let it be baked or corroded.
• Pay attention to moisture when storing. Store in a dry, cool, ventilated place to prevent direct sunlight and avoid sudden changes in dust and temperature.
• If the laser range finder is damaged, it should be sent to a special department for maintenance. Do not disassemble it yourself.
• Please do not use the laser range finder to sunlight or strong light to prevent damage to the photosensitive element Bad.
