Range Mode Selection
Choose between HCD, LOS, and BAL Modes On the Setup Menu screen, toggle to and select “Range Mode”. You can choose between the HCD, LOS, and BAL displays. The selected mode will be designated with an arrow. Return to the Setup Menu screen and continue to Target Mode Selection.
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.

IMPACT® 4000
LOS Mode
The Line of Sight (LOS) Mode is intended for rifle shooters who are using slope correcting ballistic drop data cards, ballistic cell phone applications, or other devices with ballistic programs and who are shooting at distances beyond 500 yards and with slopes greater than 15 degrees.
The range number displayed in LOS Mode is the actual line of sight range with no ballistic correction for slope. Most of the commonly used ballistic devices can provide independent slope correction for bullet drop data and require actual line of sight range input. Using the LOS range when calculating bullet wind drifts under these steep slope/long range conditions will provide a higher degree of accuracy than using the HCD range. While in LOS Mode, inclination angle of the target is also displayed on the screen. Downward angles are denoted with negative numbers.

Ballistic Preferences
For the most accurate ballistic solution, it is recommended to 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 barrel twist rate, and the interaction of gyroscopic and aerodynamic forces. The Impact® 4000 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 longrange shot precision, moving the target slightly away from the bullet’s intended point of impact during the time of flight. The Impact® 4000 can account for the effect of 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 Impact® 4000 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.

3. Name the new profile.

50

4. Enter the bullet data by selecting the icon. Select your ammunition’s caliber, and bullet weight from the list. Then, select the exact bullet you are using. This information can be found on your ammunition’s box.
Note: Bullet data may also be added by simply selecting the edit icon and inputting the following:

IMPACT® 4000

Caliber (in): The bullet’s diameter in inches. Weight (gr): The bullet’s weight in grains. Length (in): The bullet’s length in inches. Drag Fuction: See Drag Model section below. Metro: See Meteorological Conditions below. Ballistic Coefficient: The bullet’s ballistic coefficient as it correlates to the drag function. These values can be found on the cartridge’s box or on the manufacturer’s website.
51

Drag Model ­ G1 vs. G7 vs. Drag Coefficient
This information may be printed on the box if you are using manufactured bullets. If you are using custom loads, use the Drag Model listed on the packaging for your bullet. If the Drag Model is not listed on the packaging, this information can usually be found on the bullet/ammo manufacturer’s website.
In general, G1 is better for flat-based bullets typically used with pistols and muzzleloaders. G7 is more common and better for longer, boat-tailed bullets which are common for centerfire cartridges.

VS

G-1

G-7

A custom drag model is a more refined way of modeling drag for bullets because it uses the actual measured drag of a specific bullet in a ballistic solver. The app provides access to the full bullet library including custom curve data on nearly all commercially available bullets. We recommend always selecting a custom drag model when available as it will provide the most accurate solution.
Note: Drag Model options: Multi G1, Multi G7 or CD, can be imported from the GeoBallistics® App. When using these the ballistic coefficient will read “MULTI” or “1” and the Drag Model will read “MULTI G1”, “MULTI G7”, or “CD” based on your selection.

Meteorological Conditions (Metro) ­ Army vs. ICAO
This will be a standard set of atmospheric conditions used to calculate the aerodynamic drag on the projectile. This choice only applies to manual bullet entries. Using the bullet library will automatically populate Army or ICAO. For manual bullet entries, if you know the atmospheric standard that was used to calculate your bullet’s BC, select it here. If you do not know which standard is used by a manufacturer, choosing a bullet from that manufacturer in the library will let you know which standard that manufacturer uses. The difference between the two atmospheric standards is very slight but using the correct standard for your bullet BC will yield slightly improved ballistic numbers at long ranges.
Note: The ballistic solution provided by the Impact® 4000 is only as reliable as the following data provided by the user. Please contact Vortex Optics at 1-800-4VORTEX (1-800-486-7839) Ext. 5 with any questions.

IMPACT® 4000
Rifle Information
Sight Height Height from the center of the rifle bore to the center of the optic. The measurement units can be set to standard (inches) or metric (centimeters) in the Settings Menu.
Sight Height
Zero Range The distance at which you have zeroed your rifle. The measurement units can be set to standard (yards) or metric (meters) in the Settings Menu.
Elevation Offset Vertical offset from the point of aim at your zero distance. For example, you entered 100 yards for your Zero Range and at 100 yards your point of impact is 1 inch high, enter “1” here, if your point of impact is 1 inch low, enter “-1” here. The measurement units can be set to standard (inches) or metric (centimeters) in the Settings Menu.
Windage Offset Horizontal offset from the point of aim at your zero distance. For example, you entered 100 yards for your Zero Range and at 100 yards your point of impact is 1 inch right, enter “1” here, if your point of impact is 1 inch left, enter “-1” here. The measurement units can be set to standard (inches) or metric (centimeters) in the Settings Menu.
Barrel Twist Rate Barrel Twist Rate is the distance covered for each revolution of the bullet within the barrel. For example, if your barrel is denoted as “1:8”, this means the bullet will complete one full rotation every 8 inches and you should enter “8” into this space. This information may be marked on the rifle barrel, or on the manufacturer’s website. Update the Twist Rate to match your rifle.
Note: Use a negative or minus sign in front of the entered value to denote a lefthand twist. If the twist direction is not known, do not use a negative or minus sign which will denote righthand twist.
Muzzle Velocity Muzzle Velocity is the projectile’s speed as it leaves the muzzle. You can find this information on the packaging from most ammunition manufacturers, or their websites. We highly recommend that you use a chronograph to verify this information. The measurement units can be set to standard (ft/s) or metric (m/s) in the Settings Menu.
53

MV Temp (Optional) Muzzle Velocity Temperature (MV Temp) allows you to add recorded muzzle velocity as it correlates to the ambient temperature at the time of the shot. This can be important to fine tuning your ballistic solution. MV Temp is defaulted to off, but it may be turned on by toggling the switch to on. After you have toggled the MV Temp on, Muzzle Velocity will be “Disabled” in the field above. You can enter a custom muzzle velocity temperature table. The use of a chronograph is required for this information. Enter the muzzle velocity measured, and the temperature at which it was measured. Vortex® recommends entering at least two temperatures with corresponding muzzle velocities. For best results, each temperature entry should increase/decrease by at least 10 degrees. If only using two measurements, they should be close to the minimum and maximum expected temperatures expected. The measurement units can be set to standard (°F) or metric (°C) in the Settings Menu.
Note: You can import the latest temperature reading received by the app by selecting the “+ current” button.
Optic Information
Solution Units Choose the Solution Unit you would like to have your drop chart displayed with. MRAD, MOA, or inches. This information will be based off the angular unit of measurement your riflescope’s turrets and reticle are laid out in.
Elevation SSF (Sight Scale Factor) Elevation Sight Scale Factor is used to account for any inconsistencies in turret tracking, specifically the elevation turret. Default is set at “1.00,” indicating there is no tracking inconsistency. SSF is calculated by taking the elevation dialed divided by the actual point of impact change. For example, if 20 MOA is dialed, but the point of impact changes by 19 MOA, the correction factor is 20/19 = 1.052.
Windage SSF (Sight Scale Factor) Windage Sight Scale Factor is used to account for any inconsistencies in turret tracking, specifically the windage turret. Default is set at “1.00,” indicating there is no tracking inconsistency. SSF is calculated by taking the windage dialed divided by the actual point of impact change. For example, if 20 MOA is dialed, but the point of impact changes by 19 MOA, the correction factor is 20/19 = 1.052.
54

GeoBallistics® Overlays (Optional)
Vital Size
For Vital Size, estimate the diameter of the vital area of your target and enter here. The ballistic solver will take this value into account when calculating and displaying your ballistic solution in the GeoBallistics® App. If the Point of Aim (POA) is in the middle of the vital area, the GeoBallistics® App will show the range at which your bullet drop will be outside of the vital area. This is denoted by a black overlay on the ballistics chart.
Energy Threshold
The Energy Threshold, the desired bullet energy at impact to perform an ethical shot, may be entered and then the ballistic solver will take this into account when calculating and displaying the solution on the GeoBallistics® App. This is denoted by a red overlay on the ballistics chart.
Velocity Threshold
The Velocity Threshold, the desired bullet velocity at impact to perform an ethical shot, may be entered and then the ballistic solver will take this into account when calculating and displaying the solution on the GeoBallistics® App. This is denoted by a yellow overlay on the ballistics chart.
Note: For more information on these overlays please refer to the GeoBallistics® Pro Manual located at the bottom of the App Settings page in the GeoBallistics® App.
Muzzle Velocity Correction (Optional)
The Muzzle Velocity Correction can be used to fine tune the ballistic solver by calculating a hypothetical muzzle velocity based on your rifle, riflescope, and ammunition. You can input a Truing Range and Elevation, which is the shot distance and elevation correction where the Point of Aim (POA) was observed to equal the Point of Impact (POI). By clicking “Apply”, the calculated muzzle velocity will then replace the muzzle velocity in the rifle profile. This process is essentially replacing the predicted muzzle velocity with an observed drop that was built from your personal equipment. The measurement units can be set to standard (inches) or metric (centimeters) in the Settings Menu.
Truing Range will vary depending on your situation; generally, the further the truing range the more accurate the results will be. It is important to ensure that atmospheric conditions are accurately represented before completing his calculation to receive accurate results.
Note: For more information on Muzzle Velocity Correction please refer to the GeoBallistics® Pro Manual located at the bottom of the App Settings page in the GeoBallistics® App.

Using a Weather Meter with the Impact® 4000 and the GeoBallistics® App:
When your weather device is connected to the GeoBallistics® App, it can provide all environmental data to the GeoBallistics® App in order to calculate your ballistic solution. Once your weather meter is properly connected to the GeoBallistics® App, press the green button under Connect Weather Meter on the Atmospherics page to lock in the data measured from the device to your Active Profile. You may also press and hold the green button to capture an average of data while you’re holding the button, which will turn red and display a timer while holding.

From the main screen of the GeoBallistics® App, you will see

a button appear on the top left

if your weather meter is

properly connected to the GeoBallistics® App. Select this button

to toggle the weather meter compass ON or OFF. Enabling the

weather meter’s compass will populate the wind direction in the

GeoBallistics® App with the data received from the device.

Disconnecting
To disconnect the weather meter from the GeoBallistics® App, select Disconnect from the Atmospherics page under Connect Weather Meter.

IMPACT® 4000
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. · At longer distances, larger objects will be easier to range than smaller objects. · Using a stable position or platform with the Impact® 4000 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 switch to
ELR Mode.

MAINTENANCE
Cleaning
Your Impact® 4000 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 Impact® 4000 are permanently lubricated, so no additional lubricant should be applied. Note: Other than to remove the Battery Cap, 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. We recommend using the included sure fit cover for added protection during storage and transportation.

TROUBLESHOOTING GUIDE
The Impact® 4000 will not show up in the GeoBallistics® App in my device. · Bluetooth® modules of a certain age may not be able to communicate with modern devices. Devices such
as iPhone 6 and older, or Android 4.0 and older, may not work with the Impact® 4000.
I have paired my Impact® 4000 with my device, but they are not communicating. · If you have successfully paired before, and the device and Impact® 4000 will not communicate, toggle
Bluetooth® ON and OFF on your device.
My compass will not calibrate. · If the compass will not calibrate, ensure you are calibrating the compass outside and away from buildings,
cell towers, or other structures. · If the Impact® 4000 calibration is off, then repeat the calibration. The Impact® 4000 may need to be
recalibrated when changing geographic location, typically 30 miles or more.
