HCD Mode
The Horizontal Component Distance (HCD) Mode 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.

HD 4000 GB is used by the GeoBallistics®App’s on-board solver. If toggled off, the solver will use the
Atmospheric Data either manually entered by the user, imported from a local weather station via the
GeoBallistics®App, or from a compatible Kestrel®device.
Note: The Razor®HD 4000 GB’s on-board Environmental Sensors will need to acclimate to your current environment for
accurate readings. The time required for acclimation can vary depending on the current conditions. As an alternative,
you may manually enter weather data to use in the calculation of your ballistic solution until the Razor®HD 4000 GB
has had time to acclimate.
Auto-Shutoff
Allows for the Razor®HD 4000 GB’s Auto-Shutoff to be set via the GeoBallistics®App. The Auto-Shutoff
can be set to either 30, 45, 60, or 180 seconds.
Calibrating the Compass and Inclinometer
The Razor®HD 4000 GB needs to be calibrated during initial setup and should be re-calibrated every time
you significantly change location, typically 30 miles or more. Calibration is important for the accuracy of
Wind Bearing Capture Mode and the on-board compass. It may take 2-3 cycles of turning the Razor®HD
4000 GB in each direction before it calibrates. Read steps 1-5 before starting the calibration process.
Note: Calibrate your Razor®HD 4000 GB outside and away from large metal structures or objects.
Note: There is a video example in the app to demonstrate proper speed and turning of the Razor®HD 4000 GB for
calibration. You can also see product videos for the Razor®HD 4000 GB at vortexoptics.com.
Important: Do not press any buttons on the Razor®HD 4000 GB during this process unless specifically
instructed to do so in the following steps.
1. After pairing the device, navigate to the bottom of the Razor®
HD 4000 GB Settings Screen and select the “Calibrate” button
under Razor®HD 4000 GB Compass. The date and location of
the last calibration is also shown for your reference.

2. To begin the calibration process, select the “START” button. Ensure you see “cAL” in the Razor®HD
4000 GB display before proceeding to step 3.
Note: The calibration animation will begin immediately after pressing the “START” button.
3. Orient the device so that it is facing away from you and the
Measure button is closest to you, and turn the device end
over end three times.
4. Then keeping the same orientation of the device so that it
is facing away from you and the Measure button is closest
to you, rotate it around in a full circle three times.
5. Then orient the device so that it is on its side with the
Measure button to the right and the eyepiece facing you,
and turn the device over three times.

App Preferences
Auto-Locate
Auto-Locate will use your mobile device’s latitude for
ballistic calculations.
Latitude
Latitude allows for manual entry of latitude. This is disabled if
Auto-Locate is on.
Solution Rounding
Solution Rounding allows you to set as many decimal places as you
would like the app solution to display.
Ballistic Preferences
For the most accurate ballistic solution, have Spin Drift, Coriolis
Effect, and Crosswind Jump enabled.
Spin Drift
Spin Drift is a bullet’s drift left or right due to the spin imparted by
the bullet length in conjunction with your rifle’s barrel twist rate,
and the interaction of gyroscopic and aerodynamic forces.
The Razor®HD 4000 GB can account for the effect of Spin Drift on
the bullet when solving for your ballistic solution. To turn Spin Drift
on/off, tap the toggle icon.
Coriolis Effect
Coriolis Effect is the effect that Earth’s rotation will have on long-
range shot precision, moving the target slightly away from the bullet’s
intended point of impact during the time of flight.
The Razor®HD 4000 GB can account for the Coriolis Effect on
the bullet when solving for your ballistic solution. To turn Coriolis
Effect on/off, tap the toggle icon.
Crosswind Jump
Crosswind Jump refers to the small but measurable +/- vertical
influence on a bullet’s flightpath by a crosswind. The higher the
wind velocity, the greater the influence.
The Razor®HD 4000 GB can account for the effect of Crosswind
Jump on the bullet when solving for your ballistic solution. To turn
Crosswind Jump on/off, tap the toggle icon.
