ProChrono DLX Chronograph White

This is the best Chronograph I have used. It worked perfectly the first shot (.300 Win Mag). It was easy to set up and worked in my lighting conditions. We got to the range at 0900 and left at 12 noon. Sunlight was no factor with the supplied shades. I used a 13 foot string from the muzzle to the chronograph then placed a .300 win mag bore laser in the chamber to get an approximate line of sight on the target. This worked perfect. Zero issues and the bluetooth was fantastic as it not only tracked my shots, but verbally called out all the fps so I didn't even have to come off scope. I would highly recommend this product.

Good chronograph. No errors reading speed. No issues with things other buyers said about.... I do not forget to turn it off, when not in use, and batteries last quite long time. I would defiantly buy it again if I need one. I do recomand this product. I am not affiliated with manufacturer nor Amazon. Purchased with my own money.

So I got this to replace a Caldwell one of similar design. This is light years ahead of the Caldwell. The app is great and very user friendly with a lot of options to customize your shot strings. The blue tooth works very well. (no cables Caldwell!). Tells you audibly your fps so you don't have to watch the screen. Seems to have way less "errors" than the Caldwell. I have found that putting it out about 3 to 5 feet in front of the muzzle works best. As far as accuracy goes I have not tested it against a lab radar or the Garmin. So I have no live data to compare it to. I will say every once in a while I get a shot that seems to be high. Not way out of range (like 100fps) but enough to make me question it. I just throw that shot out of my shot string. Should have bought this one first!

I had trouble getting speed readings from .177 pellets. I bought this Competition Electronics Chrono and the led indoor light system. This combination allowed me to read the pellets every time. I could tell the difference between factory fresh, after cleaning, and after lubing the piston chamber. This is now my go to workbench chrono. The star downgrade is because I cannot connect the chrono via Bluetooth to my cell phone running android 10. I have tried every trick and technique I could find. Even reset my phone to factory specs in case something was out of whack. Still no luck. It will easily connect to my laptop computer and operate flawlessly. Digital Link will connect to my old phone running Android 7.1 every time. Android 10 has connectivity issues with other devices as well, like my USB borescope, so that may be the problem. Other than that, this chrono is a wonderful item to have around. Update 06/23/2021 I contacted Competition Electronics about the cell phone connection issue. They replied same day with some things to try. In order to connect, the chrono needed to be paired in Bluetooth. Also, location services had to be enabled for the first connection. When the initial connection was successful, location services was no longer needed to connect. Bluetooth pairing still is needed. I now give Competition Electronics chronograph the full 5 stars.

I had ordered one as a gift and when we set it up and took it shooting I was really impressed with it, the fact it communicates with your phone, you put in your bullet weight and can tell it notes like the manufacturer or if you are using reloads what's tip, charge and powder you used. Bur based on the information that you provided to the app it reads your bullet speed tells you the FPS, also the energy and power factor for each shot all of which it saves on the app for you to review and it will tell you your high low and averages. It is an awesome unit worth every penny just unfortunately when I ordered myself on it shown up in a slightly wore box but with the entire back half blown off from someone having accidentally shot it. Amazon did take it back and replace it with rush shipping so they made good on sending the damaged one but they may need to check stuff that is returned before it goes back on the shelf, or maybe it was a mistake. None the less the chronograph itself is awesome and I love it, and even though they sent a destroyed one they had a new one to me the next day before I even had chance to return the damaged one, so good on them for correcting the issue.

I'm using it to chrono my paintball marker and it's working out nicely. I love the iPhone mobile app over Bluetooth feature. It calls out the fps for each shot. Super easy to setup and use.... didn't even need to read the manual as it's that simple. Also, the logging and graphing feature is pretty sweet- I can create profiles for my diff markers and paint combos to track my fps & shot count. On this note, the multiple strings to record shot counts also helps to keep track of my different markers while I'm testing for historical purposes. What can be improved: Build quality- feels like cheap plastic especially the battery cover; it doesn't close tightly. But, these are more cosmetic than functional gripes. While it's nice that you can enter in the grain weight in order to calculate the Power Factor and Ft/lbs in the logs, I wish it would display the energy in Joules. Lastly, it doesn't calculate bps (balls per second) when rapid firing which some of the other chrono used for paintball features. Not a big deal but would have been gravy if this was included. Overall, happy with my purchase.

Had this since march 2022, I love using this with the app telling me the fps especially when I have it mounted on a tripod 50 yards away but make sure you place an L angle piece of metal in front of it just in case you hit it. I had a close call with my .25 cal Avenger just nicking the top back end of it. I use this on all new pellets & slugs. What changes I wish would be done: I wish for an update to the app so I can select which rifle and then let me add a new shot list Example Avenger 25 cal / 44.gr Slugs this away I could keep my different caliber rifles separated and didn't have to type a long list for what rifle and then caliber with grain weight. It would be nice to have it shorter Rifle model in a folder and another folder for another rifle model. Other then that everything is great and with app saving to PDF or Spreadsheet are great too. Like I said love it.

I can't tell you how impressed I am. Super simple setup. The optional app download went smoothly and it worked great. It was so nice not to have to wrestle with an app to get it to work on my phone. The interface is real easy. Two thumbs up!

Does not work, does nothing at all, no display, nothing Very expensive paper weight
