CaldwellBallistic Precision Chronograph Premium Kit with Tripod for Shooting Indoor and Outdoor MPS/FPS Readings green, plastic

Great Chronograph kit. All you need is a 9 volt battery to run it. The free app works great with my Android (Droid turbo2). Create a template in the app ie 308 165 amax and hit start. It will record your shots until you hit save or start new group. The template allows for notes so it is easy to and the powder charge or other note to help refer to targets when working up ocw/ladder tests. You can even take a photo through the app of your target and save with the data. Email or text the data as well.Set up is easy. Measure off 10 feet from muzzle, place the unit (a cheap laser bore sight helps verify bullet path ) following the instructions (you tube) connect the included cable to your phone and enter the set up data (distance to unit, it will do the math and calculate true MV, average, spread, energy etc and if Internet available will automatically add temperature and barometric pressure)The screen is easy to read from the bench although your phone is really the best part. It will notify you if duplicate fps and display error messages if it doesn't read a shot. I had no problem getting every shot calculated at 10 feet from bench, 100 yards and targets posted in a 3 foot wide. The 9 volt battery used about 1/2 it's power over a 6 hour period. The app displays battery.... Worked from early morning Foggy overcast through noon day sun and shade in the afternoon. I did not use the powered IR screens but are included with kit. Tripod is light but does the job. The included bag is just right to hold Everything.As for readings it had no issues with 55 grain 223, from 2600-3180 fps. 308 2500-2700 fps.If using the app, be sure to hit start initiate recording of data. Otherwise the chrono displays last shot fired on its screen.My benchrest buddys were impressed with the $100 kit. It's invaluable when trying to duplicate a good shooting factory load or see what small changes in charge or seating depth has on speed. It also verifies consistancy of your loads.I put close to 100 rounds over it so far and the only time I didn't get a reading was 100%my fault as i changed point of an relative to my bench position. A quick slide back on line and all was good.I have used a barrel mounted Chronograph at almost 4 times the cost of this kit but it was a pain to keep aligned and it affected impact. None of that with the Caldwell.Get one you'll love it..... Don't shoot it ;)

For the money I am very happy with this Chronograph. Yes the case is plastic and the tripod is a little flimsy. But for the money it is well worth it. It wouldn't connect to my iPhone 6+ until first pairing it to an old android for some reason. It worked perfectly for 80 rounds after that, no problems. The app is great. It saves time of writing everything down and is easy to use. The case is plastic and might break if it took a hard fall, but this is a sensative piece of equipment. And should be treated as such. The tripod is a little light for the job of supporting the weight of the chrono but not by much. It held up just fine. It just doesn't feel 100% rigid. I plan on testing for accuracy at the same time so I will not have it set up on windy days so I am fine with the tripod. All in all, for the money, this chronograph is great. Think about how much you will actually use this. Most people will use it only a few times a year, like me, to work up a new load or two. Don't blow a fortune on a chrono when you can use that cash to add to your firearm collection. It works, it's affordable.

I bought this because it said it would work with my android device via the headphone jack. I got the app to read on the tablet a couple times, but not consistently. It would have been nice, but I can still use it with a sheet of paper and pen. I may try an older tablet, or get the newer wireless version.The lighted arches work really well, I've never had issues getting it to read. I wish there was a way to plug them into the device itself rather than having it's own battery pack that has a long cord that doesn't reach the ground and is a bit of a pain to hang on the tripod.

I have a Shooting Chrony Gamma which has done pretty well for me. I resisted buying the Caldwell since it appeared very simple and only displayed one shot at a time with no memory. After checking out the smart phone app from Caldwell, I became interested and took a chance on this unit. It has exceeded my expectations by a substantial amount. I've had significantly fewer screen errors (screen 1 or 2 not registering the projectile passage), the app is far more user friendly than the other brand I used, and the unit is much easier to set up and take down. I was able to run through 40 different tests of 5 to 10 samples, each, in less than two hours, including setup and takedown. The app appears to have addressed some earlier criticisms I'd read as it allowed reusing the same setup data for successive runs. The tripod is short and a bit flimsy, but I have other tripods, so this is not an issue for me. The IR screens work very well indoors. You can input projectile weight and have the program display energy directly. Templates can be set up and recalled at will. Getting the data into your computer still needs a bit of work, but you can send multiple runs to your e-mail account in one go. Some room for improvement, but this is a great unit and it looks like the technical boffins listen to their customers.
