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?

Lost data after an update. now the app won't save profiles or function well. disapointing for how much i paid for the device... Update: 4/22/26 After deleting the application and reinstalling my profiles were restored. I performed a firmware update on the Rangecraft and all seems to be corrected. Just took some figuring. the more I use it the better it gets

A bit tricky, but seems I've gotten mine to sync (again). First, I'm no techie. Probably not using it for half of its capabilities, but I want to shoot and sync data (to phone) for that day to update my load data records. First use, worked flawless. Second use, couldn't get it to sync. Connected in the app but wouldn't sync. Fix was either to enable location via app settings and/or ensure VPN was killed via app management. Worked fine with no VPN and location enabled for app. Hope this helps!
