How often do I need to calibrate the Kestrel 5 Series?

Wind Speed – NK sells factory calibrated replacement impellers that can easily be installed by the customer. NK recommends replacing the impeller every 2-3 years depending on usage.

Humidity – The Kestrel 5 Series and DROP data loggers employ a highly accurate, calibrated, digital humidity sensor. Based on the sensor manufacturer's specifications and NK testing, drift on this sensor over time is minimal and field recalibration is likely to degrade accuracy rather than improve it. Factory calibration to validate and certify accuracy at a minimum of two RH points is available from NK. Kestrel 5000 series units can also be recalibrated in the field using our kit RH Recalibration Kit . During the five-year warranty period, NK will repair, recalibrate or replace any Kestrel 5 Series or DROP which drifts more than +/-1% RH/year since the date of manufacture.

Temperature – The thermistor in the Kestrel 5 series should not need to be recalibrated. If you think your sensor is incorrect, please contact techsupport@nkhome.com

Pressure – The pressure in the Kestrel 5 series should not need to be recalibrated. If you think your sensor is incorrect, please contact techsupport@nkhome.com

How do I pair my Kestrel with my computer?

Kestrel 5 series units with LiNK will need to use the Kestrel LiNK Wireless Dongle to connect with a computer. The Kestrel 5 series will not work with any internal Bluetooth modules. To connect, insert the Kestrel LiNK Dongle into an open USB port. On the Kestrel, go to the Main Menu->Bluetooth and turn it ON. Set Conct to "PC / Mobile." Open the application on the computer and select the Kestrel as the device to connect to. There is no more “pairing," "COM port numbers," or "PIN Codes" to worry about for those familiar with the 4000 series.

Why do I need to Calibrate my Muzzle Velocity when I have a chronograph that gives me a very accurate muzzle velocity?

You should always calibrate your Muzzle Velocity on the Kestrel because it accommodates for any errors. The suggested BCs are not always correct. We have seen a lot of muzzle velocity errors even with well chronographed MVs. Truing bends the algorithm to perfectly match the bullet’s flight path. Instead of hoping the prediction works, truing perfectly matches the flight path. For example, the ballistic solver expects different muzzle velocities depending on if you are using the G1 or G7 BC. However the chronograph is just measuring the actual muzzle velocity coming out of the barrel, independent of an BCs being used. Truing your Muzzle Velocity using CAL MV will always get you the proper MV to enter into the Kestrel so that your solutions are always on target.

My gun has 20 MOA base built into the rifle, how do I input this into the Kestrel?

There is no need to input the tapered base into the Kestrel. If you measure scope height at the bell of the scope, the most your error will be is 1 – 2 clicks at 1000 yards. This can be offset by measuring to the center of the windage turret instead of the bell of the scope. It is more likely that the scope click errors will do more harm than this will. Here is some reading that might help: http://www.longrangehunting.com/forums/f19/applied-ballistics-faq-167008/.

The free Kestrel LiNK Ballistics app is the perfect companion to the Kestrel Sportsman, Kestrel 5700 Ballistics Weather Meter, Kestrel 5700 Elite Weather Meter with Applied Ballistics, Kestrel 5700 Ballistics Weather Meter with Hornady 4DOF, or Kestrel 2700 Ballistics Weather Meter. Build and manage your gun/bullet profiles and download them to your Kestrel Ballistics Meter before you set out. At the range or match, secure your Kestrel Ballistics Meter to a tripod using the optional Kestrel Vane Mount and use the LiNK Ballistics app to quickly adjust the target range and direction of fire and view the shooting solution and wind rose without leaving your shooting position. It’s like having a meteorologist and ballistician standing next to you while you shoot.
