The Future is Now (and there ain't no going back) - by Brian Manzella

Just one comment on the cost of these devices. They are not cheap to produce. This is not a simple doppler radar used in parking sensors. There you only need one antenna as you are only interested in the distance. With a doppler radar for tracking objects (e.g. golf balls) you need a phased array antennas (basically hundreds and hundreds of antennas in an array).

So it is not that cheap. I am sure that as demand and competition increases the prices will come down. I remember Plasma TVs costing about £10.000 now you get them for under £500

Brian,

And if they have crazy negative AoA, they will have to have stupid crazy negative horizontal swing planes - to where the amount of twisting around to the left becomes absurd. Furthermore, it becomes increasingly difficult to duplicate the exact measure of wrist and forearm stimulation necessary to hold that clubface on line from day to day.
