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 flight charac-
teristics such as remaining velocity (“RemV”); remaining
energy (“RemE”); time of flight (“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.
Example of "Rng"clumn remaining fixed while 2 other
columns can be changed.
Range Increment
• Use while in the Range Card to enter the Range
Settings screen.
• Use and to adjust the range increment to
the desired value. You may adjust the increments
to show in 10, 20, 25, 50 or 100 units of measure
(yards or meters).
• Press to exit "Range Increment" screen.
