CALIBRATING ZERO ANGLE
Because Zero Range (ZR) is a more commonly known,
it is the default value asked for when creating a gun
pro le. Zero Angle is a comparable input but has certain
advantages over Zero Range, particularly when zeroing at
ranges greater than 100 yards or meters.
TURNING ON ZERO ANGLE:
» To switch between using Zero Angle and Zero Range,
scroll to the GUN menu and press select, then scroll to
Zero Range (ZR) and press select again.
» In the Ri e Zero sub menu, highlight Zero and toggle
left or right to switch between Range and Angle.
(When Zero Range is selected, ZR is displayed in the
Gun menu. When Zero Angle is selected ZR changes
to ZA.)
CALCULATING ZERO ANGLE:
» Enter the Ri e Zero sub menu and when Zero Angle
selected, scroll down to Cal Zero Angle and press the
center button.
» Con rm 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.
» Next, enter the distance to the target you are
using to measure your Zero Angle. This distance
should be approximately where you want your
bullet to impact with no elevation held or dialed.
Its preferable if your ri e scope has already been
at least roughly sighted in at your zero target
distance so you'll be able to easily identify where
your bullets are impacting. Be as accurate as
possible when measuring this distance and use a
quality range nder or other method to con rm,
then select Continue.
» Capture the Direction to Target by holding the
Kestrel vertically and pointing the back of the
unit at the target, 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.
