Product Description


he Caldwell Ballistic Precision Chronograph Premium Kit is a must have for a variety of shooters from handloaders trying to optimize load data to archers and air gun enthusiasts.  This kit includes everything included in the standard Ballistic Precision Chronograph package (product #626107) with a few add ons to make it even better.  The chronograph will provide an accurate velocity reading from speeds of 5 to 9,999 fps within .25% accuracy.  Caldwell achieved this level of accuracy by using a high speed 48 MHz processor and calibrating every unit after assembly before it leaves the factory. 

The chronograph also remains simple to use giving a readout of velocity in Feet per second or Meters per second on a large LCD screen.  Extra wide sun screens are included for shading in full sun operation along with a 1/4-20 threaded insert on the bottom of the housing for use with a tripod (included). 

For shooters looking to fully take advantage of this chrono, this unit includes a 15' audio jack cable which can be plugged into an iPhone or iPad to use a free app called "Ballistic Chronometer" available for download.  This app will display the velocity of each shot on the screen and record it with other data identifying the current load and environmental conditions during the shooting session.  Other data calculated by the app include average velocity, standard deviation, minimum velocity, maximum velocity, and velocity spread for shot string.  This data is stored and can easily be exported through email or SMS messaging or simply stored for recall on a later date.  Take your shooting to the next level with the Ballistic Precision Chronograph by Caldwell.

Cannot use with smartphone
Cannot hook up with smartphone with no audio jack!
I have an iPhone 8s, not exactly the latest one in the brand. It has no audio jack, so I can only use the chronograph the old fashioned way, by looking at the window on the housing. For me, this is almost useless.

Save your money
Doesn't give correct speed of projectile.
Won't change from FPS to MPS.
Total waste of money.

Does not support new tech smart phones
Needs blue tooth. 2021 everything blue tooth’s. Old technology with the supplied audio jack.

New to chronograph
I hemhaw'd around looking at all the options and checking reviews and wound right back at the Caldwell brand and now have the premium Chrono kit. Am new to reloading and just getting more into longer range shooting. I am able to know how my store bought ammo is performing with my equipment and base reloads on these data points. I think I have made a good choice for what I am doing.

The entire equipment setup does not weigh a lot and the tripod is not heavy duty and could possibly get blown over if the wind picks up. I knew that going into this from other reviewers complaining about that but I am fine with that. Nothing a Target stand stake or two won't correct if wind picks up.

It is fresh it the box and I only have a couple hours of time with it and time will tell but I am pleased with what I have seen at this point.
