The AB Kestrel includes two automated ballistic
calibration tools that dramatically increase accuracy at
long range. First, muzzle velocity is calibrated by firing
at a range where the round is supersonic. The user
enters the actual drop at that range, and the AB solver
computes the calibrated muzzle velocity automatically.
Second, for long range shooting - where the round
is transonic or subsonic - AB uses the actual drop at
another range to automatically compute the drop scale
factor (DSF).
This DSF provides a finer level of control in the transonic
and subsonic flights than BC-Mach/Dist tables,
especially when used with the custom drag curves that
Applied Ballistics has computed for many common
bullets. While AB's solver supports the use of G1 and G7
ballistic coefficients, these custom drag curves offer a
new level of accuracy that cannot be matched by the
conventional G1/G7 ballistic tables.
Custom drag curves are accessible through the AB Gun
Loader software. See page 21 for download location.
To transfer your Kestrel’s real-time and logged data
wirelessly and automatically to a laptop, PDA or
smartphone (Android only at this time), follow these
setup steps. If you do not have a Bluetooth unit you
will need the PC Interface cable.
Enable the kestrel’s BluETOOTH Capability
• Press to enter the Main Menu.
• Use
or
to highlight “Bluetooth,” then press
.
• Use or to change from “Off/Disabled” to “On/
Ready.”
set BluETOOTH Range
In Bluetooth screen:
• Use
or
to highlight “Range”.
• Use and adjust the range to “Low” (3ft), “Medium”
(10ft), or “High” (30ft). NK recommends using "High".
Obtain your kestrel BluETOOTH pIn and ID
For added security, each Kestrel comes with a unique
PIN and ID number to ensure proper pairing.
In the Bluetooth screen:
• Use
to highlight “Info,” then press
to view your
unique ID and PIN.
pair your kestrel with your Computer
First, make sure your Kestrel unit’s Bluetooth and your
computer's Bluetooth are enabled. Open the Bluetooth
management software on your computer to add a
Bluetooth connection and follow the prompts to enter
the PIN. A COM Port will be assigned in the communicator
software. To understand which COM Port is being used,
please check your computer control panel settings.*
