1. BRIEF DESCRIPTION  
LRB 7X50 (SPD) Laser Range Finder Binocular is an  
advanced Laser Range Finder system that provides instant  
distance measurements consistently and accurately. The  
stereoscopic device provides convenient observation with both  
eyes. The user can measure the distance to an object without  
loosing sight of the target. Therefore, the LRB 7X50 (SPD)  
substitutes a need for two separate devices (binocular and range  
finder) combining both requirements in a single device.  
There are black dots in the image.  
A LCD (Liquid Crystal Display) is installed in the optical channels  
of the device. Due to manufacturing imperfections in the  
production process of the LCD, small black dots, scratches and  
other blemishes might be visible. Those blemishes are strictly  
regulated for maximum allowed number, size and location. It does  
not degrade the product's performance.  
The outstanding optics provide a sharp, clear image under all  
conditions. LRB 7X50 (SPD) is utilizing a revolutionary digital  
design, which is outperforming any other product in its class and  
price range.  
Range measurement cannot be obtained.  
Check if range detection mode is activated (message READY  
appears on the LCD display)  
Check if Active Button is pressed  
The unit sends invisible, eye safe laser beam pulses to the target.  
The returned beams are captured by the digital circuitry. The  
time differential allows us to calculate the distance to the target.  
Make sure that neither your hand nor finger is blocking  
objective lenses (Laser emitting lens or Receiver lens).  
Check if the unit is steady while pressing Action button.  
6. STORAGE AND MAINTENANCE INSTRUCTIONS.  
2. APPEARANCE OF THE DEVICE  
Precautions: LRB 7X50 (SPD) is a sophisticated precision  
optical instrument equipped with electronics. Therefore, it  
should be handled with due care.

Avoid shocks and sharp jolts.  
Clean optical surfaces with professional camera lens  
cleaning supplies.

To clean the exterior of the device, use a soft clean cloth.  
Keep away from heating appliances and central heating.  
Remove the batteries when storing the device for long  
period of time.

TARGET REFLECTION MED - when the number of  
steady received reflected signals is in medium range and  
enough to make positive conclusion about the measured  
distance;  
TARGET REFLECTION HIGH - when the number of  
steady received reflected signals is qualified to be enough to  
make reliable conclusion about the measured distance.  
Patent pending

Made in Canada  
The displayed statistical qualification of the reflected signal  
characterizes variation in expected accuracy of measurements. At  
qualification HIGH the accuracy of measurements is stated as  
±1m or ± 0.1%. At lower rates of statistical qualification the  
expected accuracy may marginally degrade.

The display presents message LOW BAT – when voltage of the  
primary 9-volt battery drops below 7.2 volt. At this point the  
System is still functional but the battery should be replaced as  
soon as possible. The system can operate at the voltage levels  
above 7 volts.

The System operates in the setting Modes, which are displayed  
as follows (refer to fig.3):  
Pressing Action button (6) (fig. 1) at this point triggers a distance  
measuring session, and the result will be displayed in numerical  
form (4) (fig. 3) (if measurement is unsuccessful then four dashes  
‘----‘ will appear in the numerical area). Please note that the target  
must be over 20m away.  
5.1. Preparing the Device for Operation  
Unbolt a screw and open battery compartment cover at the  
bottom of the device.  
Insert one 9V battery (sold separately) into the battery  
compartment observing correct polarity.  
If the Action button (6) is held (pressed) for more than 3 seconds  
the System automatically enters SCANNING mode. This feature  
is not available on all versions.  
Close up the battery compartment cover, tighten the screw.  
After changing the battery, it is recommended to run the CL  
(CLEAR) mode (refer mode selection procedure).  
At this mode the System repetitively performs distance measuring  
and displaying. The time interval between measurements is  
approximately 1 second.  
Take off lens caps  
Look through the eyepieces (1) (fig. 1).  
Adjust interpupilary distance by turning lever (9) (fig. 2)  
until two images converge into one  
The maximum measuring range for most objects will be 1512m.  
The maximum measured distance will vary greatly depending on  
the reflectivity of the target, weather conditions and more.  
Make dioptric correction individually for each eye by  
rotating rubber rings (4) (fig. 2) of each eyepiece  
Target reflectivity depends on its color, surface finish, shape etc.  
Bright colors are more reflective than darks. A polished surface is  
more reflective than a rough one. Larger targets are easier for  
distance measuring. Measuring a target faced at 90o (perpendicular  
to the laser beams path) provides optimal results.  
Bad weather conditions (rain, fog, snow, mist) will reduce the  
maximum measured range.  
Now your unit is ready for operation as a conventional 7x  
binocular (passive state).  
5.2. Distance Measuring Procedure  
a. Measuring state  
When the Rangefinder is in the passive, low power state, the  
LCD Display is blank (transparent).  
Pressing any of the operating buttons activates the System and  
the Display. Initially the System always assumes READY mode  
of operation and word READY appears on the Display.  
Bright sunny days will reduce performance as well  
While the unit will work through many glass types, measuring through  
glass will affect the results.
