GPS Golf Balls
The other day we mentioned a new ruling that would allow the use of GPS rangefinder devices in some golf tournaments. Now comes news about the use of GPS receivers in golf balls themselves. The advantage? Well you could use it to analyze just how long your shot was, or analyze the trajectory of the shot to achieve longer drives. But perhaps the most useful feature for most people is the ability to locate the ball after you slice it into the woods.
Most of the golf balls I use are those I find in the woods. If people can suddenly find their lost ball in the woods via GPS my supply will dwindle! 
Does anyone know if these GPS Golf Balls are in production and available anywhere? Also quite keen to know about their accuracy.
My father is visually impared, he is not blind he can still see fairly well but he can not track his ball after it is hit. it moves to fast for him to see it and then allways has to look and look and look for his ball and many times does not find it. Is this product still available?
