New Caldwell Chronograph Displays Shot Data on iPhone or iPad

Android OS ChronographCaldwell will be introducing a new chronograph in early 2014. By outward appearance, this is a fairly conventional unit, with optical (light-tripped) sensors and “V”-profile sky-screens with plastic diffusers supported by rods. However, the big news is the data output. The new Caldwell Ballistic Precision Chronograph can display shot data and string averages on iOS devices such as the iPhone and iPad. A software App allows you to save the data on your iPhone, and you can even export the data via email. That’s handy if you want to archive your test results in a spreadsheet.

Along with the iPhone/iPad display, Caldwell’s new chronograph features a front-facing display screen on the green, barbell-shaped chrono body. As with most other chronographs, the Caldwell unit records velocity of each shot, average velocity (of shot string), Standard Deviation, and Extreme Spread (difference in FPS of fastest shot and slowest shot). One nice feature of Caldwell’s new chronograph is that it can be calibrated. That sounds promising, but remember that to calibrate any chronograph you need test ammo with a very accurately determined baseline velocity. In any case, Caldwell asserts that this new Chronograph is more accurate than some other units on the market, because it runs a faster processor and because it has the calibration option. We haven’t tested the unit yet so we can’t verify claims of improved accuracy.

Android OS Chronograph

The Caldwell Ballistic Precision Chronograph comes as a complete package with carrying case, sky-screens, and data cable. No price has been announced, but we expect it to be under $150.00. Incandescent lamps, which are suspended above the sensors, will be available as an optional accessory. These lights permit the unit to be used indoors.

Android OS ChronographAndroid OS Capability in the Future?
Currently, the new Caldwell Chronograph is only able to send data to iOS (Apple) devices. However, the data cable is not Apple-specific, so there is a chance that we may see Android OS compatibility at some time in the future. At SHOT Show in January 2014 we’ll ask the Caldwell technicians about compatibility with Android smartphones and tablets.
