How does the TV camera follow a golf ball in flight?

I've noticed on TV how precise a camera can follow a golf ball from tee off until it lands. How do they do that?|||They are well practiced, but they are also a long ways off. They pick up the ball off the tee, then zoom in so you can see it. Notice that you don't see it right away, you see the golfer pick up his tee or whatever first. This gives the camera man time to get the ball on camera appropriately.|||multiple cameras|||ZOOM!|||the camera men are amazing. i've seen it and wondered if it's magnetix or something like that, but it's only camera men.|||its the camera guys job|||Well... they make the golf ball swallow a special little transmitter. The ball usually refuses at first, but with a little bit of coxing and some sweet talk it eventually swallows it.





Wait, this sounds all too familiar?





Anyway, once inside the ball, the transmitter can only be activated by an extremely powerful strike from an external scource. Hence, the driver!





Roughly 2-3 seconds after the ball is in flight, the device begins to transmit its signal. The networks have a specially equiped TV camera that has a receptor mounted right above its lense. This receptor picks up the signal from the transmitter and follows the golf ball until it come to rest in the fairway.





And there my friend is how the TV camera follows a golf ball.
