Caldwell Ballistic Precision Chronograph

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.

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 Also the bullet data is pretty far out of date.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.

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.

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.

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 !
