If the vertical point-of-aim provided by the solver does not
match match the point-of-impact of your rie, Axial Form
Factor can be modied to calibrate the solver and provide
an even more accurate solution.
CALIBRATING AXIAL FORM FACTOR:
» Scroll to and select Gun in the Ballistics Menu.
» After accurately inputting all other gun, bullet, and scope
parameters, as well as wind values and direction of re,
scroll to Cal Axial FF and press select.
» Conrm your approximate latitude is entered in the Kestrel
and then select Continue. If you dont know your current
latitude the Kestrel LiNK Ballistics App has a command to
update your Kestrel’s latitude using your phones GPS.
» On the Capture Enviro: screen, begin updating your
environmental measurements by pressing Start Capture.
» The quickest way to ensure your Kestrel is reading accurate
weather measurements is to alternate swinging the Kestrel
by the lanyard and checking the Temp value displayed
until the temperature value stops changing, at which point,
select End Capture.
» Scroll the Range value to match a target approximately 300
to 800 yards away which will give you a clear indication of
average point of impact, then press Continue. Further is
generally better but if you have a hard time identifying a
clear average point of impact nd a closer target. Inputting
an accurate distance to target here is key! Use a quality
range nder or other method to conrm the distance to
the target.
» Capture the Direction to Target by holding the Kestrel
vertically and pointing the back of the unit at the target,
AXIAL FORM FACTOR
then press Capture.
» Capture the Wind inputs by opening the impeller
cover and while holding the Kestrel vertically, point
the back of the unit into the wind, then press Start
Capture. After measuring at least a 5-6 second
sample of wind that is representative of your
shooting location, press End Capture. The wind
values just captured will be displayed. If desired,
values can be scrolled to and manually changed. If
the wind capture values are satisfactory highlight
Continue and press select.
» Based on the target and environmental inputs given,
the Kestrel will provide the expected elevation
correction required for your target on the Elv line.
Dial or hold that elevation value and shoot at your
intended target until an accurate average point of
impact can be determined. If the elevation provided
is not accurate, adjust the Elv value in the Kestrel until
it is correct for your target.
» Adjusting Elv will automatically calculate a Axial Form
Factor value. When the Elv value shown matches
the elevation hold needed to hit your target scroll
to Continue and press select. The Axial FF value is
capped at 0.90 and 1.10. If adjusting the Elv value to
match your target causes the Axial Form Factor value
to change above or below those values, go back and
check your scope and the gun and other inputs to
your Kestrel.
» Once the Elv value matches the elevation required to
hit your target select Continue and then press Select
to conrm your new Axial Form Factor value.
