Crosswind strongly influences the accuracy of sharpshooting, becoming the largest error component at long ranges. Even medium crosswind velocities (~5 m/sec) along the flight path of a bullet can cause 1 meter deviations at 500 meters. Temperature, humidity and density altitude also play a part in ballistics performance, and are incorporated into most advanced portable targeting computer applications. The Kestrel 4500, with its ability to accurately measure all of these parameters in a four-ounce, pocket-size package, is consistently on the military sniper’s “most-wanted” list of desired equipment. The new Kestrel 4500 adds often requested crosswind calculation and wind direction.
