Kestrel

The Kestrel 5700 Elite Weather Meter with Applied Ballistics 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. It also contains a powerful ballistics calculator to help you hit your long-range shot on the first try. This meter 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.
