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
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 appropriate
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.)

Drag Curves
The Kestrel with Applied Ballistics allows you to use G1 or
G7 drag curve model, or AB's custom drag curves.
• To select the appropriate drag curve, scroll to "DC."
• Use

to scroll through options.
• If a custom drag curve is used, no further adjustment is
necessary. If using G1 or G7 drag curves, you must adjust
the BC by scrolling down and editing to the proper value.
For more information on the custom drag curves, please see
page 18.
Calibrate Muzzle Velocity
This allows you to calibrate your muzzle velocity based
on the actual drop of a round at a range where the bullet
is supersonic. With the range and the drop entered, the
Kestrel automatically adjusts muzzle velocity to match.
