Product Description

The Ballistic Precision Chronograph provides accurate velocity measurements across a wide range of shooting conditions. Higher 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 end result is the ability to provide much better accuracy than other chronographs on the market (+/- .25%). Although technologically advanced, the unit is designed to be simple to operate, displaying velocity in Feet per second or Meters per second on the large built in LCD screen.

The Chrono can also deliver the shot string velocity data through the 15′ foot audio jack cable (included) to smartphone/ mobile device. A free App is available for download that displays the velocity of each shot on the phone screen and records it with other data identifying the load and environmental conditions. The App also automatically calculates Average Velocity, Standard Deviation, Min, Max and Velocity Spread for the shot string. The data is stored and can be exported via Email or simply recalled for reference at a later date. The sunshades are extra wide for better reliability on sunny days and are constructed of a durable synthetic material. Measures from 5 to 9,999 FPS. There is a ¼-20 threaded insert on bottom of housing for tripod mounting, operates on a 9 Volt battery (not included).

    Should have got this a long time a go. it works great, you don’t need an I phone for it to work, but I have a old iPhone 4s and it work great. Go to the app store and find the Caldwell app and install and run it.Tested 4 air rifles so far with 5 different pellet manufactures and was happy with the results. Very easy to use and set up also has a spot for a spare 9volt battery, you can use a camera tripod for a stand.

    This an updated review. As previously stated, the chronograph works very well and is easy to setup. I was having problems with the Android App working on my Samsung Galaxy S4 using the supplied TRRS audio cable. It just would not sync at all. I found a solution by using a standard printer USB cable along with an on-the-go USB connect for my S4. It now works as advertised. Customer service was very helpful in resolving my issue. It’s all good!

    Was a little finicky to set up, but after that worked well for a while. The app for my android phone was nice. After about a year the rear sensor quit.

Question: My Chronograph is displaying ERR2 and/or ERR3 errors after the chronograph has been turned on and in the standby mode, how can i fix this?

Answer: Caldwell Shooting Supplies has identified an issue with electronic components on a small group of Ballistic Precision Chronographs that were shipped to our dealers and distributors in late 2014 and January of 2015. The defective chronograph inventory has been identified, isolated and repaired. If your Chronograph is displaying an Error2 and/or an Error 3 code in normal outdoor light conditions your Chronograph could be affected.
