One guys I know is always hitting these great shots etc, but as yet I have never seen one on the course. But the main thing is, when talking about distances he insists that he knows he can hit his hybrid 194 yards and his 5 iron 185 yards and so on. Problem is he normally duffs it! He has also just bought a top of the range GPS system because he is so accurate with his distances. He works out to the inch how far it is to the green and will then top it straight into the lake!
