No way to pre-load shot lists
Shot lists must be created when shooting, so there is no way to enter load data in ahead of time. This makes it a real pain and time consuming to type all this in while at the firing line during round development.
Also, no way to add shots to a saved group, or add a shot manually in a string in the event of communication issues via the cable or Bluetooth.
Lastly, the ability to add a picture to the saved shot string is great, but it can only access the camera, so you can’t use a photo from the library. It would be better to also allow the user to select an image from the library so that they can quickly take images of all groups at once, and add them to the saved shot groups later. (This would also allow the user to user images that have been annotated with group size by other apps)
Disappointed that there has been no updates in 4 years.

sclugsto,
App to chronograph went to sheot after last App update
I downloaded the App after purchasing the chronograph. Took it to the range and it interfaces and logged the data from shots perfectly. I updated the App on my iPhone 11 and it stopped working. After buying a new dongle from Apple, putting the App on my newer work iPhone, my wife’s 14, getting a brand new Chronograph from Caldwell it still does not interface to the App. So for the headache and hassle I’m recording date the old fashion way, pen and paper one shot at a time at the range and putting it into a spread sheet from the first working session before the update. It is disappointing that a big part of the total tool is useless artist on a bore.
lordmorgul,
Works fine on iPhone6s (corded)
This works fine on iPhone6s with the cord plugged in. You must turn off Bluetooth (in the app! Not just your device settings!) before it will recognize a cord connected device, which is a bug the developers should fix.
Recorded data well, with the cord being removed and reinserted several times as we switched stations during the day.
Highly recommended, it is simple and works well to relieve the mundane effort from data recording. Took shot data at faster than one per second. Bright sunny day at over 95deg F. May not be the most accurate device, but seems good enough for my needs.

Chrono works as expected
I bought this to measure my reloads and this chronograph works great. Tripod is sturdy, whole unit and app works great. The only downside I would have to say is the app in which we can add brands of cartridges and bullet size. It does not want to add three digits for bullet size. It will use the first two digits only. For example if I would insert 0.224 it will show 0.22 and for 9mm I would but 0.355 it would put 0.36. Also the app will not add to and existing brand. If I wanted to add Federal brand of cartridge it will create a new field. Also could add plated bullets brands or just played bullets to the app.
hmmmAllNicknamesTaken,
Zero care for existing customers
I realize this chronograph I’m using is a few years old, but it was working just fine until I dated my phone to iOS 16. That said, Caldwel has had plenty of time to fix the issues! I even sent an email to the company and got no response. It is now time to move on to a different brand. The chronograph itself may be working, but you will have to do all the math yourself if you’re using an iPhone. This unit is not designed to show totals, only one velocity at a time, on its display. That is to be done in your phone. And when it doesn’t work, well, like I said, time to move on to a different brand.

Needs to be able to sync with apps on other devices
I like the Chronograph and the app but it would be a lot nicer if the app would sync to other devices. Personally I like being able to record the data on my iphone but since the phone screen is so small it would be really nice to sync that data with my ipad and be able to view and edit the data on my ipad.
Also the bullet data is pretty far out of date. There is no bullet data for Hornady ELD-X bullets as yet and these have been out for a quite a while now.

Hfdpyro,
Works great, no problems
I didn't have a problem with connection to my ipad. I had a problem connecting it to my iphone, but it was my fault. When you open the app for the first time, it will ask permission to access the mic. I clicked no and it wouldn't connect until i gave the app permission. The only thing that keeps it from 5 stars is the app will not rotate when you rotate the ipad. Very frustrating when i have it in the keyboard dock. If they fix it, it would be 5 stars all the way.

Hangs Up !
The Chronograph works very well- never had any problems with the unit . How ever, about 20% of the time the software on the app freezes. The only way to clear the problem is to ‘delete ‘ the app and then go to the App Store and download again. The worst part of this exercise is that you loose all the data that was stored . So, I’ve been recording the data by hand . The problem occurs in saving the data . The unit works great but the SW stinks !

Caldwell Ballistic Precision Chronograph
I opened the box and check that all the parts were there, they were.
I read the instructions until I understood each step, then I took it out and gave it a try.
I connected the 15' cord and opened the app on my iPhone 6s, turned on the chronograph all in the correct sequence listed in the instructions.
Everything worked flawlessly the try, the only option I didn't try was the Bluetooth option. At this time it was not necessary since I had the 25' cord supplied with the unit.
I'm 100% satisfied with my purchase, I may invest in the lighting kit if it becomes necessary.
Great product, I would recommend it to a friend for sure.

Fix This App!!!
Doesn’t work anymore. Since the newest iOS it wont connect via cable to the chronograph. I didn’t pay $100+ for the hardware for you to just not update the software. There’s people still buying this and it just doesn’t work. Fix this! Unacceptable
