Competition Electronics Digital Link Bluetooth Adapter, Black

with the corresponding app on your phone or tablet you can compile a lot of useful information.I shoot IPSC and like to keep my PF as reliably close as I can to 125. I managed to get the powder feeder in my dillon press reliably delivering the same amount of power and together with the bullet feeder getting reliable OAL. then all that remained was some range time to figure out how much titegroup I needed to get close to 125.this worked a charm and makes it easy to play around with OAL, projectile weights and different powders. you can store all the info in the app for future reference.

Works great (especially in low light or heavy shade) and sends the shot velocity directly to my phone or iPad via bluetooth and the free app that I downloaded for my phone and iPad. It only reports the last shot velocity. Nothing else, and you can't just scroll back through the app to see previous velocities. It DOES keep me from having to squint at the display on the chronograph, which is what I wanted. Very good. On my iPhone the app shows the numbers about 1 inch tall, and the iPad shows about 2 inches tall, the remainder of the screen is just blank. I would have liked to be able to scroll through the previous string or switch strings but that is only possible if I wait for an all clear and walk to the chronograph and do the regular resets, re-displays, and new string controls on the chronograph itself. I like it, especially when the regular display is in deep shadow or low light and just can't be read from the bench, I just wish it did more than report the last shot's velocity.

I tried this unit based on a recommendation from a friend. It best thing after sliced bread (for the shooting community)You can initially set up the data on a computer because it is easier to type. you can upload to the cloud and import that data to other devices. It communicates very well with the Ipad and or the phone very well. It will only connect to one device at a time. However, if you don't have your portable device at the range the unit will connect to your device once you are back home from the range.You can export files to an excel file and print charts, graphs and tables. It doe take some know how on basic computer skills. How to export and import files, how to transfer files between the cloud and your portable device.I will be testing this against the magnetospeed and report back with my results. But I think this unit has better data transfer options.

The digital Link works excellent and saves a lot of time in between shots. I like to check each one of my shots when i reload so i know how fast they are going and this add on is excellent. It saves all of my shot strings right on my phone so i can see each shot at a later date so i don't have to right anything down and it even provides a voice readout after each shot, which can be customized at different time intervals or turned off all together. You can also export and print you data too. This paired with my phone instantly (Samsung S5) and even if i walk away with my phone in my pocket and come back it reconnects automatically. The only note is that the app has to be open on your phone when in use. The menus on the app are easy to use and understand and even use your phone to update the temperature.

Best accessory for testing your bullet speed. My brother and I shoot high end PCP air rifles. We both have ProChrono Chronys. I bought the Digital Link Bluetooth to see how it would work. This is so easy to use, links to my iPhone and my iPad. No more writing down shots and plugging in the results to a spreadsheet. It gives results in a graph display, CSV file, Text file, and you can message the results to anyone. You can customize the shot header for each group. It even speaks out the bullet speed on my phone after each shot so that I don't have to look. If you have a ProChrono, this is the must accessory to get. The price is so reasonable, why not. I liked it so much, I bought one for my brother.

Setup was very easy the hardest part was getting to blue tooth pairing on my phone. I have used this several times and it makes using the chronograph very convenient. I sit at the bench with my phone create, select, edit or delete my shots or strings and review stats SD, ES, average velocity, etc. without disturbing other shooters by having to go out in front of the firing line. When I’m done I can email or upload the data to a computer in several formats to store or do additional work. No wires or cables to tip over or worry about I think it would be great if this was built into all chronographs.There is room for improvement with the app. You can only upload one string and one format at a time. It would be nice to be able to select multiple strings and formats to upload at the same time. It would also be nice to be able to edit the shot string information. ie I was doing a round robin and forgot to change strings. I could delete the shot but could not manually add it to the correct string.

This thing's a huge help. The connection aspect is totally painless, range seems great, and if you're on the public line somewhere and can't really get to the chrono during a firing period and have more than one thing to chrono you can just create different entries for different loads and record them as you go and then come back later and get the exact results. Sure beats trying to squint at the screen from 12 feet away in who knows what lighting.(There's an update, see below) I do have some nits with the software. It shows the power factor for each shot, and there's a screen where you can get average velocity but there's no average power factor which is the one number I actually want from the thing in the first place.Still, it's so useful I'm going with all five stars but I'm hoping they update the app occasionally.Update: Four days after I posted this they updated their page with averages to include average, minimum, and maximum power factor for the whole string. Perfect!
