Caldwell Ballistic Precision Chronograph Kit, MPS and FPS Reading with Adjustable Tripod, LED Light Kit, and Carry Case for Shot Velocity Testing on Firearms, Archery, Airgun, and Paintball

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.

Works very well I like it only gripe is the stand is very cheap

The third time I used it it started throwing error codes and will not read anything now. I emailed Caldwell ballistics and got one email back from them and then they quit responding. They have no plans to refund, replace or repair it. This thing is junk. Stay away from it and buy a quality chronograph.

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

Works well. Doesn't work so great in the sun. It overheats fast and you have to give it a break. Aside from that it's fun and helps to tune your shooting equipment.

I returned this chrono, because it was very difficult to set up. The reading were accurate as I compared it to a much more expensive unit. I found it to be very cumbersome to put together and set up. For those reasons I returned it. I gave it a 3 star due to it's accuracy.

Had trouble pairing with Bluetooth to phone. I called customer service and said to use the app in yellow for this g2 unit, not the green app. Works absolutely perfect now, great product.

Really great product for serious pcp rifle target shooters.
