The Caldwell 4001147 Ballistic Precision Chronograph With Bluetooth is a versatile velocity-measurement tool designed for shooters who want reliable data without complicated setup. Factory-calibrated electronics, a high-speed 48 MHz processor, and extra-wide sun screens work together to deliver consistent readings from 5 to 9,999 feet per second on a large, easy-to-read LCD screen.

This chronograph is equally at home on the rifle range, archery lanes, or airgun and paintball fields, capturing shot strings and sending them via Bluetooth or the included audio cable to the Caldwell app on your smartphone. The app logs velocity, calculates statistics like average and standard deviation, and stores load and environmental notes for later review. Lightweight construction, a 1/4-20 tripod mounting insert, and battery-powered operation make it simple to transport and position downrange, reflecting Caldwell’s focus on practical innovation for everyday shooters.
