I used the chronograph today for the first time - It was nice being able to look at my phone and hear the velocity of the shells and see them on the screen. Great product for the money - I'm dialing in my Duck loads and the chronograph is just what I needed!

I have found the ProChrono DLX to be a really good reliable chronograph. I use this chronograph to test my 12 gauge trap load recipes and I really like the way it works (links up with) with my iPhone. It will verbally tell you each shots FPS reading through your phones speaker and will also display the read out in large easy to read numbers on the iPhone screen. I would definitely recommend this to anyone interested in a good reliable chronograph.

Links right up with my phone, tablet, and even laptop with no issues. Reads within +/- 1 FPS of the one this one is replacing, and for the price, I can't find anything to really complain about.

Used this for tuning an Airforce PCP air rlfle, worked great, looking at fine tuning some handloads now for some of my powder burners to try and get even better accuracy

You could spend more money, but why? This is an excellent Chronograph, download the app, install batteries, set it up and shoot. Everything is controlled by your electric device, all the data you need stored neatly and easily available to view, or print. This Chronograph will give you all the data you need even graphs, it's just numbers and your money you figure it out.

I have owned a ProChrono DIGITAL chronograph for almost 20 years. That unit works and has worked flawless for all these years. However, this year, I wanted to upgrade.
I looked at several different manufacture's chronographs in the same price range before making my decision. After comparing them, I stayed with ProChrono.
With onboard blue tooth, the DLX is a real upgrade.
Before making this purchase, I called Competition Electronics. I talked to a "real person" who answered "all" my questions.
Competition Electronics is an excellent company. They stand behind their products - and they stand with their customers.
I am completely satisfied with my purchase. An awesome chronograph at a reasonable price.

Works great, really like the Bluetooth feature and the information it provides on power factor and ft/lbs of energy.

This is my first chrono and it does everything it is supposed to do. I love the bluetooth feature and it connects easily to my Android phone. Grafs customer service was excellent as always.

I purchased this after disabling my Caldwell chrono with a 10mm bullet. Almost happy I did, as this chrono is much, much better. The phone software actually works on an Android phone, and works well. The chrono is better at picking up the bullets than the Caldwell, and having access to your data on a computer is a tremendous help. Overall, I am very happy with the upgrade.

Really like the bluetooth feature. Download app, turn on, good to go. No more straining to see display.

I now use this as my main CHRONO as it has Bluetooth built in and connects to my android in 3 seconds. The app saves all the data so you can export later if you wish. Or, if you have a cell signal where you are shooting, you can just email the shoot string to yourself. When you are load testing for 300wm, that can turn into some expensive data. I still use my mag speed as a back up if it is really low light or wind is bad where the tripod becomes unstable. But that has only happened once in the last 2 months. Example data cut and paste
Name 300wm eldx 212
Number of Shots 10
Extreme Spread 37
Standard Deviation 12
Shot 1 Shot 2 Shot 3 Shot 4 Shot 5 Shot 6 Shot 7 Shot 8 Shot 9 Shot 10

Very easy to set up and gives readings visable from the bench
PROCHRONO with Bluetooth

I own one other Chrono and had purchased another brand with Bluetooth, it did not work at all, was returned. This one worked right out of the box. Extremely easy to set up with Android, application quite intuitive. First time I used it I didn't expect it to be calling out the speeds on my phone. Nice! From what I can tell speeds are accurate.
Not thinking, I fired a few rapid shots, it does not catch all of them. My fault but just a heads up. Would highly recommend. So far my use has been with handgun. I shoot a couple of days a week and am competitive in benchrest rifle.

This new model is essentially the same as the Pro Chrono with the Bluetooth module add-on but with this one it's built in. It is very easy to use and the freely available software is very useful.
Sync's up easily with Android, iOS, Windows, or Macintosh.
