Mr. Moore:
Mr. Huckaby is my uncle, and only when I had him as a teacher. My Dad doesn't even need or want to be called that. Call me Tom, please.
And my answer to your question is this: if one is bad enough to hit the ball to a place where absolutely no information is available as to distance, then he needs all the help he can get, techological or otherwise.
Obviously there are places one can hit the ball where a bushnell would be his only hope to get a distance (other than pacing it off, as Geoffrey says). In these rare times, I'd say the help is only a benefit for one and all, wouldn't you? Or do you advocate further punishment of those who are already punished enough?
