QUICK TIPS:
Compass must be calibrated in order for directional
features to work in Horus mode, and it can only be
calibrated in Weather mode.
Pressing will allow you to exit out of a particular screen.
When a ballistics parameter is underlined, this means that
the value is unable to be changed manually on the current
screen either because it is a calculated value or one
determined by the sensors.

3. Environment
These three main data groups determine an accurate ring
solution. The rst step in getting a ring solution is
selecting your gun.
GUN SELECTION
The Gun Selection screen allows you to choose a precong-
ured gun or build your own. You may create and store up to
9 user-created guns. A user-created gun is dened as a gun
that has been modied for one or more parameter values of
the New Gun or any of the library guns.
When a New Gun is modied, the name instantly changes
to UserGunX (where X is a number sux to ensure the name
is unique). If a library gun (whose name ends in a letter) is
modied, a number will appear at the end to create a unique
name. If a library gun (whose name ends in a number) is
modied, a letter will appear at the end to create a
unique name.
• Turn on the unit. From the Main Horus screen, press
to access the Main Setup Menu.
• Press to highlight “Gun Selection.”

• In cases where the bullet is supersonic, there are no
dots next to the muzzle velocity value.
MV-Temp Table
This allows you to enter and maintain a table of muzzle
velocities based on temperature. If an entry is input
into the table, the muzzle velocity is applied at all
temperatures (this means that the value is then locked
and cannot be altered by using  and on the gun
information screen) If two or more entries are input
into the table, the Kestrel uses the linear interpolation
and the temperature sensor to determine the appropri-
ate muzzle velocity (Note: this value will only change
if the temperature changes and you exit and re-enter
the gun information screen; once a muzzle velocity
value is entered for a particular temperature, you can
not make another muzzle velocity value for the same
temperature.)
• To access MV-Temp table, scroll to MV (Muzzle
Velocity) to highlight it and press , then use
to scroll to MV-Temp and press to enter.
• Press while “New entry” is highlighted to enter
the Table Item screen.

screen.
BC-Dist Table
This allows you to enter and maintain a table of ballistic
coecients based on distance. If only one entry is input
into the table, the ballistic coecient is applied at all
distances (this means that the value is locked and cannot
be altered by using and on the gun screen). If two or
more entries are input into the table, the Kestrel uses the
linear interpolation and the target range to determine the
appropriate ballistic coecient (Notes: this value will only
change if the target range changes; once a ballistic coef-
cient value is entered for a particular distance, you cannot
make another ballistic coecient value for the
same distance.)
• To access the BC-Dist table, scroll to BC (Ballistic
Coecient) to highlight it and press , then use
to scroll to BC-Dist and press to enter.

ENVIRONMENT SCREEN:
The Environment screen contains all atmospheric parameters
such as temperature, station pressure, and relative humidity.
Setting the “Auto” parameter to “Yes” automatically imports
the Kestrel’s sensor data into the Environment screen. The
“Auto” parameter can also be set to “Manual” when it is
highlighted by using  or while in the Manual setting
the temperature (Temp), station pressure (SP), and relative
humidity (RH) can be manually adjusted.
• Use or to highlight a parameter.
• Use  and to adjust the values for each parameter.
Coriolis will default to “Yes” unless you manually change it to
“No”. While it’s on the “Yes” setting, this means that coriolis is
taken into account for the ballistics solutions.
Density altitude will automatically adjust according to the
adjustment of the relevant environmental parameters. This
parameter cannot be manually changed because it is a
calculated value.
*Note: station pressure (“SP”) is pressure reading is
unadjusted for sea level. Sometimes this is mistakenly
called barometric pressure in ballistics software. Barometric
pressure is a pressure reading adjusted for sea level. When
shooting, station pressure is required. Station pressure can
be measured with the Kestrel by setting the reference altitude
to zero on the Barometric Pressure screen in weather mode.
RANGE CARD SCREEN
The Range Card screen shows detailed information about
the ballistic solution at various ranges that apply to the
currently selected target and gun. The screen displays
three columns comprised of the Range (in the left column)
and two other variables. The other variables that can be
displayed are ballistics solutions based on “Wnd1”; “Wnd2”;
“Lead”; “Elev”; or further information on bullet ight charac-
teristics such as remaining velocity (“RemV”); remaining
energy (“RemE”); time of ight (“ToF”); and maximum
ordinate, or height above the line of sight to the target
(“MaxO”). Please see Page 26 for a sample Range Card.
• Use or to scroll to a particular range.
• Use  and to scroll across and view all available
parameters.

BALLISTICS SCREEN
The Ballistics screen displays complete information about
the ballistic solution that pertains to the currently selected
target and gun. The only parameter whose value can be
altered in this screen is the “Range” (this can be done by
using  and to adjust the value).
• Use or to scroll to a particular parameter.
• Use to enter into a parameter screen for further
information about it or change unit of measure.
• Use to return to the Ballistics screen.
Note: An R or an L will appear beside each solution to indicate
which side of the target you should aim.
ATrag Signature Feature
TRUE DROP
In an ideal world, shooters would go into the eld knowing
exactly how their chosen combination of gun and ammuni-
tion will perform, calculated ballistic solutions would always
be correct, and a properly delivered shot would always hit
the target. In the real world, ballistic data is often imperfect,
and even well delivered shots often miss.
The best way to deal with this is to allow ballistic parameters
to be adjusted to reect what is actually observed. When
this is done correctly, overall accuracy can be signicantly
enhanced. The Horus Kestrel includes a Drop Truing screen
to support this valuable function.
• When all parameters are set, press to escape.
• On the Gun screen, use to highlight the
“True drop” item
• Press to enter the Drop truing screen.
• In the Drop Truing Screen, use or
to highlight the parameter you wish to change.
• The parameters that can be adjusted are “BC” (ballistic
coecient), “MV” (muzzle velocity), or “Range”.
• This adjustment is made so that the calculated
elevation correction matches what is actually
observed.
QUICK KEYS: DIRECTION OF FIRE &
WIND SPEED
The Direction of Fire (DoF) and Wind Speed (WS1 & WS2)
Quick Key feature allows you to quickly and easily change
the values of these parameters from the Main Horus screen
without entering into the Target screen. It minimizes the
number of button presses and time by instantly capturing
these values from one screen- the Main Horus screen.

GLOSSARY OF TERMS
Active gun: When a gun is made active, ballistic solutions
for that gun pertaining to all active targets are readily
displayed. Ballistic solutions for guns that are inactive are
not displayed.
Aiming/Ballistic solution: This consists of sight corrections
for windage, elevation (and in the case of a moving target,
lead) for a selected active gun and target, along with other
calculated values such as bullet velocity and energy. On
the main Horus screen, only elevation and windage are
displayed. On the Range Card and Ballistic Info screens,
detailed ballistic solution data is available.
Subsonic: The speed at which the bullet is slower than
the speed of sound. Bullet velocities in this range will be
displayed with a large dot to the left of the value.
Target: A target is characterized by its direction, range,
inclination angle, and applicable wind; a moving target has
a direction and speed of motion. Targets are identied by
a single letter: up to ve can be described, designated by
the letters A through E. It’s important to note that wind is
specic to a target – each active target has its own wind
specication.
Transonic: The speed at which the bullet slows to the
speed of sound. This is also seen as the boundary between
supersonic and subsonic. Bullet velocities in this range will
be displayed with a small dot to the left of the value.
