Competition Electronics ProChrono DLX Chronograph White

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.

I have been previously using a Caldwell that gave me trouble from day 1. With it I would constantly get error codes and have to keep turning it off and on. If I was lucky about 50% of shots would provide a reading. It took me hours with their tech support to get their app working. And then it was always buggy. i was never happy with that purchase. This chronograph has worked flawlessly and I've had no trouble with the app. My advice: Run as fast as you can away from Caldwell and buy this.

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.

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 handload my own ammunition & a good chronograph is an important tool to have for finding the best load. I previously had a ProChrono but without the bluetooth feature. Had it for over 10 years but it just quit working and I need my chronograph. Bought another brand chrono here but I was less than satisfied with that cheaper model. Looking for a new one, I came back to ProChrono & this one with the bluetooth feature is just what I was looking for. No cables needed & it connected easily to my Samsung S22 & my PC. I can create a customized shot list & the saved data can be saved & printed out as a PDF file. I save those to my Access database. Or it can also be used as chrono remote. If your looking for a good, reliable chronograph, I highly recommend this one.

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!

If you like frustration this is the chronograph for you. I purchased it for a pellet gun so less than 900 ft/sec and it's inconsistent as hell. I've wasted so much time and pellets on this pos I've considered shooting a hole through it. But here I am again wasting more time writing a review on it but I'm so frustrated I figured I'd better do my part in creating awareness and hopefully get people to avoid this thing. It doesn't say anything about "low" lighting in the description when it comes to using it but trust me it is VERY critical that it be in just the right amount of SUNLIGHT or it won't work. Yes it has to be sunlight not any other type of lighting but hey they got the answer for it buy a lighting kit from them for another $90ish so get ready to dump more money. I refuse to because it's expensive enough and I dumped enough money on it purchasing the unit itself. Buy a chinese unit at a fraction of the price of the Competition Electronics ProChrono DLX. Trust me you got nothing to loose. You can buy a chinese chrono for what Comp Elec gets for the dam lighting kit alone! Oh and getting it to display the shot string live on your phone another pain in the a$$ shows the last shot only and nothing to show you or tell you why... couple hrs of searching was enough for me. I'm not looking for graphs and all this crap simply display the string of shots live while I'm tuning on the gun. Nope that's too simple and easy I guess. I don't typically leave reviews cuz I'm not a picky person and can usually fix any issue I come across but when something starts wasting hrs of my time then I get a little salty... stay away from this junk

Used it for the first time this week. Seems to be well built, accurate and easy to use. I like how it has an app but you don’t have to use it. Will still display each number and leave it on the screen until you take another shot. Worth the money.
