The Kestrel Shooter’s Weather Meter with Applied Ballistics combines cutting edge environmental sensing features with long-range shooting ballistics information in a single hand-held device. The supplied Applied Ballistics® software provides the following:

• The full ‘Litz’ library of G1 and G7 referenced Ballistic Coefficients (BC’s)
• Custom drag curve modelling, useful on targets beyond the supersonic range of the bullet
• Ballistic Calibration (truing) feature which will ‘train’ the software based on actual bullet impact
• PC Loader software; build firearm profiles on your computer and transfer them via wire or Bluetooth

The Kestrel 4500NV meter with Applied Ballistics Technology measures up to 15 environmental parameters and allows users to select from either G1 or G7 ballistic coefficients (BC) when calculating a trajectory at the range. The handy, portable meter also offers the ‘Litz’ measured BC library of over 225 bullets, which is considered to be the most extensive source of measured data for modern small arms bullets.

Users can also coach the Kestrel Shooter’s Weather Meter with Applied Ballistics software to match an individual rifle based on actual bullet impacts at long range with the ballistics calibration feature, which offers even more accurate data points. With easy access to more accurate data, the user can calculate increasingly precise trajectory predictions in a hand held tough Kestrel product

• Calculate accurate elevation and windage targeting solutions for long range rifle shooting.
• Use either G1 or G7 ballistic coefficients, OR select from the entire library of Applied Ballistics Custom CurvesTM for more than 200 common long range bullets.
• A sample set of the Applied Ballistics Custom Curves is pre-loaded on the Kestrel Shooter’s Weather Meter. The pre-loaded Custom Curves are:

• .308 175gr Sierra Matchking
• .300 WinMag 190gr Sierra Matchking
• .308 230gr Berger Target Hybrid
• .338 250gr Lapua Scenar
• .338 300gr Lapua Scenar
• .338 300gr Berger Target Hybrid
• .338 300gr Sierra Matchking.

• Access to the entire Applied Ballistics Custom Curve library requires the Applied Ballistics Profile Loader PC application together with either Bluetooth® data transfer capability on the Kestrel Meter and PC, or the Kestrel Computer Interface accessory. The Applied Ballistics Profile Loader is a free download from the Kestrel website.
• Train the software to match your specific rifle based on observed impacts at subsonic and supersonic ranges with the True Muzzle Velocity and Drop Scale Factor capabilities. Built-in crosswind calculator and target range estimator.

Kestrel With Applied Ballistics with Bluetooth

Kestrel 4500NV Applied Ballistics Meter with integrated Bluetooth® technology offers the ultimate in hand held and accurate environmental data. Now, both real-time and logged data can be transferred wirelessly and automatically to a laptop or PDA, making a Kestrel Shooter’s Weather Meter with Applied Ballistics and Bluetooth® technology the perfect tool for virtually any job that requires quick and reliable data.

Available with Bluetooth® Data Transfer – Recommended for Full Gun and Bullet Profile Customization and Backup

What’s the difference between the Applied Ballistics and the Horus version?

The main differences between the two models is The Applied Ballistics model has a different truing application with drop scale factor, it has bullet length as a standard gun input (used to calculate spin drift) offers +\- angle input and has the ability to use G1,G7 and custom drag profiles. The unit comes Pre loaded with 7 drag profiles and the Gun loader will have over 100 custom drag profiles to use.

Target Screen

Once the ballistic data is entered, the direction of fire (DoF) is programmed using the Target Screen. This is done by pointing the unit at the target from the firing position and pressing `Capture` to log it. This sets the compass bearing of the target so the crosswind effect can be computed.

Main Screen

The Main AB Screen displays the critical data for making the shot. When the Kestrel is in full automatic mode, the AB software will immediately calculate the windage (W) and elevation (E) setting for this specific shot scenario, constantly updating the firing solution as long as the unit remains facing into the wind. If preferred, an average wind speed may be captured or a value manually entered. Up to five targets may be active at any time and it is quick to switch between their respective firing solutions.

Range Card Screen

The Range Card Screen shows detailed information about the ballistic solution at various ranges for the currently selected gun & target. Should a correction be required to the theoretical ballistic data based on observations in the field, a ‘True Drop’ adjustment may be made so that the elevation correction matches what is actually observed to significantly enhance overall accuracy.

Environment Screen

The Kestrel 4500NV AB also operates as standard Kestrel 4500 Weather Meter providing readings of wind speed and direction, crosswind, headwind / tailwind, temperature, wind chill, heat index, dew point, relative humidity, barometric pressure, altitude, density altitude, wet bulb temperature, digital compass and time & date.
