KESTREL 5700 ELITE METER WITH APPLIED BALLISTICS The Kestrel Elite combines sophisticated environmental sensing features with long-range shooting ballistics information in one powerful hand-held device, delivering proven elevation and windage solutions for extended long-range shots with unprecedented accuracy. It employs the Applied Ballistics bullet library of custom drag models, an exact measurement of your bullet's drag profile plus corrections for Aerodynamic Jump, Spin Drift, Coriolis, and Drop Scale Factoring to achieve accurate extended long-range shots. The Kestrel Elite measures up to 15 environmental parameters including wind speed/direction/chill, crosswind/headwind/tailwind, temperature (air and wet bulb), humidity, heat stress index, pressure, density altitude, dew point, and altitude. The rugged design is fully waterproof, floats, and features a large high-contrast backlit screen with a night vision preserving light for easy viewing in all conditions. The Kestrel Elite allows users to select from either G1 or G7 ballistic coefficients (BC) when calculating a trajectory at the range. Users can also train the Kestrel Elite with Applied Ballistics software to match a specific rifle based on observed impacts at long range with the ballistics calibration feature, which offers even more accurate data points for users to rely on. Use these features via the Applied Ballistics Profile Loader through a USB cable from your Windows PC (cable sold separately). Includes AA battery, lanyard, and protective pouch. The Kestrel Elite is proudly designed and manufactured in the USA, and is backed by a 5-year warranty..
