The Environment screen contains all atmospheric
parameters, such as temperature, station pressure, and
relative humidity. Setting the “Update” parameter to
“Yes” automatically imports the Kestrel’s sensor data
into the Environment screen. The “Update” parameter
can also be set to “No” when it is highlighted by using
or ; while in this 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.
Spin Drift will default to “Yes”
unless you manually change it
to “No.” When on the “Yes” setting, the Spin Drift is taken
into account for the ballistics solutions.
Coriolis affects all automatically calculated in the bal-
listic solutions. In order to turn off Coriolis effects, please
set the Latitude and Direction of Fire to zero.
*Note: station pressure (“SP”) is pressure reading that is un-
adjusted 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 alti-
tude to zero on the Barometric Pressure screen in weather
mode; although, the ballistics solution will use station
pressure regardless of the altitude settings.

Inclination Angle
Inclination angle is the angle between the target and
the horizontal as seen by the shooter. This variable is
expressed in the Target screen as “Ideg” or “Icos,” where
Ideg is in degrees, and Icos is the cosine angle. These
can be manually adjusted by highlighting one and using
the and to change the value. Changing one will
automatically change the other appropriately.
Target speed
• Use or to highlight “TS.”
• Use and to adjust the value.
Target speed Estimator
This function estimates the speed
of a target based on range,
movement, and time.
• When “TS” is highlighted, press
button to enter Speed of
Motion screen.
• Use to highlight “Estimate” and press to
enter Speed Estimate screen.
• Use or to highlight a parameter.
• Use and to adjust values for each parameter.
• When all parameters are set, press to escape.
• An "Accept" screen will appear, scroll to "Yes" if you
would like to accept values. Use to select the
highlighted option.
Target Direction
• Use to highlight “TD.”
• Use and to adjust “L-R” (left to right) or “R-L”
(right to left).
