BALLISTIC LASER RANGEFINDER
The Razor®HD 4000 GB is an essential companion for
the extreme hunter, and shooter. The angle compensated
ballistic laser rangefinder features four targeting modes
(Normal, First, Last, and ELR) and two ranging modes,
Horizontal Component Distance Mode (HCD) and Ballistics
Mode (BAL), for any ranging environment. Using an array
of built-in environmental sensors in conjunction with the
state-of-the-art GeoBallistics®solver and patented Vortex®
Wind Bearing Capture Mode, the Razor®HD 4000 GB will
raise your level of long-range precision shooting ability to a
new height.
The Razor®HD 4000 GB pairs, via Bluetooth®, with your
mobile device and the GeoBallistics®App. Scan QR code
on the next page to download the GeoBallistics®App with
your Apple or Android device.

RAZOR®HD 4000 GB
In order to have accurate compass readings with your
Razor®HD 4000 GB, it is highly recommended to
calibrate the Razor®HD 4000 GB during initial setup
and should be re-calibrated every time you significantly
change location, typically 30 miles or more. Calibration
must be performed outside and away from large metal
structures or objects. See the Product & Ballistic Manual
via the QR code for more information on how to calibrate
your Razor®HD 4000 GB using the GeoBallistics®App.

BASIC OPERATION
Battery Installation and Replacement
To insert a new battery, flip up
the finger tab on the Battery Cap
and unscrew, counterclockwise,
to remove. Insert a CR2 battery
with the positive side (+) facing
outwards. Reinstall Battery Cap
and ensure it is tightly closed.
Power Up
Once the battery is installed, the Razor®HD 4000 GB is in
ready condition – the normal power-off condition when not
ranging. To power up the Razor®HD 4000 GB from ready
condition, press and release the “Measure” button. The
HCD or BAL ranging screen will display. The auto-shutoff
feature can be adjusted to 30, 45, 60, or 180 seconds.
See the Auto-Shutoff section on page 16.
Battery Cap
Low Battery Icon
The Low Battery Icon displays
once the battery reaches 25%
life and stays on until there is no
power or the battery is replaced.
Adjust the Eyecup
The Adjustable Eyecup on the Razor®HD 4000 GB
twists in and out so any viewer can see the full field and
enjoy comfortable viewing and ranging – with or without
eyeglasses. When not using eyeglasses or sunglasses, it is
recommended to keep the eyecup fully extended. For best
viewing when wearing eyeglasses, twist eyecup in to allow
closer contact to your glasses.
Focus
Adjust the Diopter
until the image is
sharp. Make note of
this Diopter setting in
case you need to set
it again.

Utility Clip
The Razor®HD 4000 GB comes with a Utility Clip on the
unit’s left-hand side. You can switch the side of the Utility
Clip by unscrewing the 2mm hex screws on the left-hand
side, and the 2mm hex screws on the right-hand side of the
unit. Reinstall the Utility Clip on the right-hand side of the
unit and the Utility Clip Plate on the opposite side of the

MODE SELECTION
Changing Modes on the Razor®HD 4000 GB
The Razor®HD 4000 GB is factory set to the angle
compensating HCD Range Mode, Normal Target Mode,
Brightness Level 4, default Auto-Shutoff at 30 seconds,
and distance to the target displayed in Yards.
To Change Modes
Press and release the
“Measure” button to power
on the unit, and then press
and hold the “Menu”
button for at least four
seconds. Once the Mode
Selection screen displays,
release the button.
As you progress through
Mode Selection, you may
exit at any time and save
your settings by pressing
and holding the “Menu” button for at least four seconds —
The unit will then return to the power-up condition.
Use the “Menu”
button to activate
the Mode/Display

Use the “Measure”
button to toggle
through each Mode

Target Mode Selection
The Razor®HD 4000 GB provides four target modes:
Normal Mode, First Mode, Last Mode, and Extended Laser
Range (ELR) Mode.
After activating the Mode Selection, press the “Measure”
button to toggle between Normal Mode, First Mode, Last
Mode, and Extended Laser Range (ELR) Mode. Press the
“Menu” button to save your desired choice and continue
through to the Ranging Mode Selection screen.
Normal Mode
The Razor®HD 4000 GB comes preset to Normal Mode.
This is the standard mode providing the target’s range
with the strongest range result. Normal Mode is the
recommended target mode for most situations.
First Mode
This mode displays the closest distance when panning
and scanning. It is ideal for ranging a smaller target in
front of other larger or more reflective objects.

12 13
RAZOR®HD 4000 GB
Extended Laser Range (ELR) Mode
This mode allows for ranging smaller, less reflective targets
at extended distances. It is ideal for ranging when Normal
Mode is unable to obtain a desired range. A longer response
time may be required to receive the desired range. For best
results, it is recommended to be used on a tripod.
Ranging Mode Selection
Choose Between the HCD and BAL Modes
Press the “Measure” button to toggle between the HCD
and BAL displays. Press the “Menu” button to save your
desired choice and continue through to the Range Unit
Selection screen.
BAL ModeHCD Mode
HCD Mode
The Horizontal Component Distance Mode (HCD) will be
your primary mode when not using the on-board ballistic
solver. The yardage number displayed is the critical
horizontal component distance. The displayed HCD
yardage number is corrected for shot angle and needs
no extra user input; shooters simply use the appropriate
level ground bullet drop for the range displayed and shoot.
Archers use the appropriate level ground sight pin for the
range displayed.
Note: To correctly account for wind, you need to know the line
of sight distance to the target as it is based on how far the arrow
or bullet travels to the target. This can be achieved using the
BAL Mode.

This number is automatically
calculated into the wind/drop
solution provided in the display and in the GeoBallistics®
App. If you are not using the on-board solver, enter the
slope incline number into ballistic programs or field cards
to help calculate precise bullet drop in mountainous
terrain. To use the Razor®HD 4000 GB on-board ballistic
solver, you need to be in BAL Mode.

RANGING
With the Razor®HD 4000 GB powered up, position the
reticle on the target object you wish to range, then press
and release the “Measure” button to get the distance
measurement. If the laser is not able to range due to the
reflectivity of the target object, or because the target is too
close, you will see a display similar to that shown below. To
range a new target, simply re-aim and press the “Measure”
button again.

RANGEFINDING TIPS
Laser rangefinders work by emitting a brief pulse of light
aimed at a target object. Distance is determined by the
amount of time taken for the light to emit and return to
the laser’s internal receiver. A laser’s ability to read range
can be affected by many things, mostly relating to the
target object.
• Light colors will usually reflect better than dark ones.
• Snow, rain, air quality, and fog will have adverse effects
on ranging ability.
• Dull or textured surfaces will not reflect as well as a
hard, shiny surface.
• Ranging under cloud cover can improve laser
performance compared to bright, sunny conditions.
• Solid objects, such as rocks, will reflect better
than bushes.
• Flat surfaces perpendicular to the laser will reflect
better than curved surfaces or surfaces angled in
relation to the laser.
• Ranging over water can sometimes cause false
reflections and readings.

34 35
RAZOR®HD 4000 GB
• At longer distances, larger objects will be easier to range
than smaller objects.
• Using a tripod to steady the Razor®HD 4000 GB will
greatly increase your ability to range small targets at
longer distances.
• If you are having difficulty ranging an animal or object,
try ranging a different nearby object, or use the Scan
Feature to pan back and forth while watching for
changes in range number, or switch to ELR Mode.
MAINTENANCE
Cleaning
Your Razor®HD 4000 GB requires very little routine
maintenance other than periodically cleaning the exterior
lenses. The exterior may be cleaned by wiping with a
soft cloth. When cleaning the lenses, be sure to use
products that are specifically designed for use on coated
optical lenses.
• Be sure to blow away any dust or grit on the lenses prior
to wiping the surfaces.
• Using your breath, or a small amount of water or pure
alcohol, can help remove stubborn dried water spots.
Lubrication
All components of the Razor®HD 4000 GB are
permanently lubricated, so no additional lubricant
should be applied.
Note: Other than to remove the Battery Cap, Utility Clip and Wrist
Lanyard, do not attempt to disassemble any components of the
rangefinder. Disassembling of rangefinder may void warranty.
Storage
If possible, avoid storing your rangefinder in direct sunlight
or any very hot location for long periods of time.
