I am sure that it has been thought of before, but there would be a couple of reasons why it hasn't came about yet. Firstly a tracking device is very expensive, and would probably put the cost of a Golf ball beyond economic viability. Secondly, you couldn't just put it in the centre of a ball, because a core is solid and the tracking device would affect performance. Another and most important reason is, the R&A and USGA are unlikely to pass it for competition use, because it is too tachnologically advanced and gives an advantage to those use it over those who don't. Golf balls are easy enough to find if you keep your eye on it when it lands, but the easiest thing to do is keep it in the fairway!

Tracking the ball is looking at the ball as it approaches you.This happens when you bat. It's important to track the ball compared to guessing when swinging the bat to hit ball. This takes practice and focus on what you're doing.
