I was in New Zealand for vacation over the Holidays. I was lucky to play a very nice golf course in the South Island. Rented clubs and bought my two sleeves of my standard Pro V1 that I usually play. Had been struggling all day with yard to meter conversion, playing with no range finder. Came across a 130 meter par 3. Tried the calculation of adding 13 to 130 to make it roughly 143 yards. Pulled PW, true strike and it landed on the front edge of the green and tracked directly at the hole and dropped in for my first ever hole in one after playing golf for 16 years!
