The Kestrel Shooter's Weather 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 train the Kestrel Shooters Weather Meter 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. With easy access to more accurate BC data, shooters have everything they need to make a much more precise trajectory calculation in a compact and durable Kestrel meter design. THIS KESTREL IS BLACK IN COLOR.
