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.*
