Caldwell Ballistic Precision Chrono with Bluetooth Premium Kit,Green

Worked great for 9mm. Not good at all for 357 mag. I might have had it too close. I noticed alot of gunpowder residue all over it after the shooting session from the 357. Probably need to move it 20 ft away instead of 15ft

Bought last november, just got around to use for my bow and have tried numerous batteries would not turn on. Turned it over and tore apart and the power plug was not plugged into its wire harness. Plugged in and turned on..

Great tool to use for sighting in a rifle. I shot through this and I put the data in a ballistic calculator. The box was as much as 400FPS off from the chronograph. The app works perfectly fine Bluetooth to my phone. This chronograph is a great value when compared to others. It is only 3 buttons so it is very easy to use. The design is straight forward, put it 10-15 feet in front of the barrel and let’er eat.

Really great product for serious pcp rifle target shooters.

For a cheap chronograph, its works as it should. Bluetooth worked well. App is pretty basic, but so is the chrono. After multiple uses it works as it should. Has not missed shots and errored like previous versions. Tripod it comes with is pretty weak and wobbly.
