I've used the chronograph at the range a few times now and the unit itself seems to work well, however, it has been a struggle to sync the unit with the app. I get a message in the app saying sync was successful, however, there is no shot data showing up for most of the sessions recorded on the unit. Just updated the firmware this afternoon and that did not address this issue. When will Athlon add profiles for 22LR Rimfire ammo like SK Rifle Match?

I'm really upset about a few things, mostly I can't use the phone app after a past update. I am using a Samsung Galaxy Note 9 and the app no longer connects properly. Seems every time I updated the chono, I would have some new issue. That wasn't a huge deal until the last update I installed, totally screwed things up. Currently, I cannot get any data to sync with my phone and the newest firmware update starts to download and then fails/disconnects at about 20%.

Great app, useful feature set and simple UI. It connects to and works perfectly with my Athlon chronograph. I have heard there were some bugs in earlier versions but they seem to be completely resolved because I have not experienced any negative issues. Compared to other ballistic solver apps I have used, this is more straightforward and easy to use.
