Caldwell Ballistic Precision Chronograph Premium Kit with Tripod for Shooting Indoor and Outdoor MPS/FPS readings.

The Ballistic Precision Chronograph provides accurate velocity measurements across a wide range of shooting conditions. High accuracy was achieved by using a high speed 48 MHz processor and by designing a circuit with an advanced data interface that allows each unit to be computer calibrated at the factory after assembly. The Chrono can deliver shot string velocity data through the included 15 foot audio cable to an iPhone, iPad, iPod Touch, Android 2.1 or newer and Kindle Fire Tablets.
