I have used the PRGR a few times outside without the tripod and it seems to be much more accurate. I had it on the range today and it correlated almost exactly with what I see on TrackMan indoors. The only difference is that I do not think that the PRGR is calibrating for elevation, so the distance is closer to what I would see at sea level, but for practice, the ball speed and swing speed numbers are amazingly close, hitting 7 irons, Callaway UWs, three wood and driver. I am back to being very excited about this device again.
