I havent been able to get the R10 to work once at the outdoor driving range. I have an iphone and have the latest 4.3 software loaded on r10. I have also uninstalled and removed device and then reinstalled and paired the unit again. i have also calibrated the unit. The device is setup at 7 feet away, no one else even on the driving range and the unit is flashing green. I take my shot and the unit shows a red light and then goes back to flashing green, In the app nothing happens.
