Tips For Taking Accurate Measurements

The Kestrel 5700 Elite Weather Meter with Applied Ballistics takes the guesswork out of long-range shooting, even out to the transonic and subsonic flight range of your bullet.

The Kestrel 5 Series platform offers a large, high-resolution and contrast display with ease of font readability. It also includes a built-in dual color backlight, extra-strong polycarbonate lens, AA battery operation and optional LiNK iOS and Android wireless connectivity and app support.  Like all Kestrel meters, the Kestrel 5700 Elite is drop-proof, dust-proof, waterproof and able to withstand harsh environments without damage – so it can accompany you to the range, hunt, match, deployment or engagement for years to come. A range of carry pouch options makes it even easier to take your Kestrel meter with you.

Buy the Kestrel 5700 Elite with LiNK and get the power of the free Kestrel LiNK Ballistics app. Build and manage your gun/bullet profiles and download them to your Kestrel 5700 Elite before you set out. Choose from the extensive Litz library of custom bullet drag models for the most precise transonic and subsonic range solutions available anywhere. At the range or match, secure your Kestrel 5700 Elite to a tripod using the optional Kestrel Vane Mount and use the app to quickly adjust the target range and view the shooting solution and wind rose without leaving your shooting position. The LiNK Ballistics app even lets you set up multiple targets for single-screen viewing – just about an unfair advantage! It’s like having a meteorologist and ballistician standing next to you while you shoot.

LiNK enabled units can also be wirelessly paired with LiNK compatible laser rangefinders to seamlessly integrate target data into the ballistic solution for unparalleled speed and accuracy.

In addition to the ballistics solver capabilities, the Kestrel 5700 Elite is a comprehensive weather meter for measurement and logging of primary environmental conditions, including wind speed and direction, temperature, humidity, heat index, pressure and altitude. Paired with the Vane Mount, the Kestrel 5700 Elite becomes a compact, easily-deployable weather station. Your data log can be transferred to an iOS/Android device wirelessly with the LiNK wireless communication and the Kestrel LiNK app, or to a Windows/Mac device with either the wireless USB Kestrel LiNK Dongle or waterproof USB Data Transfer Cable (Both sold separately).

Kestrels have been put to the test in some of the harshest conditions on the planet. U.S. Special Forces, combat weather teams, wildland firefighters, smoke jumpers, Mt. Everest expeditions and auto pit crews are just a few who rely on a Kestrel to provide them with the crucial environmental data they need. Watch any on-screen meteorologist during a hurricane, and you’re sure to spot a Kestrel in action. With a Kestrel 5700 Elite, you can put accurate shooting solutions and environmental measurements in the palm of your hand, anywhere your adventure takes you.

As can be seen in the pictures below, place your thumb on the bottom of the unit and slide the latch from the “Locked” to the “Unlocked” position. The battery door should pop up enough that you can remove it. If you have trouble opening the battery door, some slight pressure DOWN on the battery door itself with your other thumb may help release the latch.


Opening the Kestrel Battery Door ... Permalink

First slide in the tab at towards the top of the unit, then gently press the bottom part of the battery door down until it snaps into place.  Ensure that the O-ring remains in place on the battery door when closing.

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

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.

Any of the LiNK Ballistics applications will allow you to transfer gun profiles to your Kestrel. So Kestrel LiNK Ballistics for iOS or Kestrel LiNK Ballistics for Android will allow you to use a mobile device to transfer gun profiles but you would need to have the LiNK (i.e., Bluetooth) model. If you are using a Windows computer, you can use the Applied Ballistic Profile Loader (Version 42 or higher).

NOTE : Please be aware that currently the Applied Ballistics Profile Loader cannot be used with Bluetooth for Kestrel 5700 devices; therefore you will need to purchase the USB Transfer cable to transfer files with a Windows PC.

The free Kestrel LiNK Ballistics app for Android and iOS is the ideal companion to the Kestrel 5700 Ballistics series of Weather Meters. Build and manage your gun/bullet profiles and download them to your Kestrel Ballistics unit before you set out. The app is also the perfect way to display your ballistic solutions remotely via Bluetooth. Another option is purchasing a Kestrel HUD

Currently mobile devices cannot perform firmware upgrades. An upgrade is defined as going from a 5 Series Kestrel Sportsman or Kestrel 5700 to a Kestrel 5700 Elite with Applied Ballistics. To upgrade your Kestrel Sportsman or Kestrel 5700, you will need to connect to a Windows or MAC computer. More info can be found on the Kestrel Upgrade packages.

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.

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/.

If you are getting NaN shown as a solution, then you have a bad value in your gun profile. For instance, the bullet length is set to 0.000. This also confirms that you have an older version of the firmware as later versions will check for these conditions before loading the gun on the unit. Check your profile and update your firmware to resolve this issue. If you are getting Bad Enviro as a solution, then there is an issue with one of the sensors. If the issue persists, then there might be a sensor failure. The best course of action is to fill out a Kestrel Service request and send it in.

Typically this will happen if the Kestrel is placed near a magnet or magnetic source. Things such as the MagnetoSpeed Riflekuhl or other chamber chillers, electronic hearing protection, or maybe even magnetic buttons on your pocket. Any magnet can affect the compass calibration. Also storing the Kestrel in a metallic enclosure such as a gun safe can have an affect on the compass calibration.
