The Caldwell Ballistic Precision Chronograph with Bluetooth Kit is a velocity measurement tool built for shooters who want hard numbers on their loads. It reads projectile speed from 5 to 9,999 fps at +/-0.25% accuracy, which covers everything from rimfire and centerfire rifle work to handgun, archery, airgun, and paintball use. The Bluetooth kit version pairs the chronograph with a smartphone or tablet through the free Caldwell app, so velocity strings log automatically instead of being copied by hand. For handloaders developing accurate loads, this is the data that drives consistent results down range. See our full range of chronographs for comparison.
A high-speed 48 MHz processor handles the timing math, and the unit is factory calibrated after assembly so readings hold their stated +/-0.25% accuracy out of the box. A large screen displays velocity in feet per second or meters per second. The premium kit ships complete: the chronograph unit, two sun screens to manage harsh light, a carry case, a tripod, and an infrared LED light kit that lets you keep shooting under low-light or indoor conditions where standard sky screens struggle. A 15-foot audio jack cable is included for data transfer, and the app handles logging, averaging, and shot-string analysis. The chronograph runs on a single 9V battery. Overall kit dimensions measure 17.9 inches long, 10.6 inches wide, and 4.3 inches tall.
Set it up downrange of the muzzle, pair the app, and you have a velocity record for every shot in the string. That data tells you whether a powder charge is consistent, whether two lots of factory ammo actually shoot the same, or whether an airgun or bow is holding its rated speed. The included light kit extends usable time into the evening and indoor ranges, where light-dependent units quit. If you want a barrel-mounted alternative, look at our Caldwell G2 chronograph, or pick up a spare LED light kit for low-light sessions.

Yes. The premium kit includes an infrared LED light kit that lets the unit read velocities under low-light or indoor conditions, where chronographs that rely on natural sky light typically fail to register shots.
It does. The chronograph reads velocities for firearms, archery, airguns, and paintball, which makes it useful for checking arrow speed or confirming paintballs fall within field velocity limits, in addition to load testing.
The chronograph unit runs on a single 9V battery. Keep a spare in the carry case so a dead battery never cuts a range session short.
