I have been lucky to have two holes in one with Titleist balls and clubs, these are as follows: 1. 29th of May 2014, at Waterkloof Golf Club in Pretoria South Africa. Hole in one on the 5th par 4 measuring 378 meters (413 yards) - I have been told this could be a world record. Used a 913D2 Titleist Driver with a Titleist Pro V1x ball. 2. 2nd of September 2016, at Modderfontein Golf Club, Johannesburg South Africa. Hole in one on the 14th par 3, measuring 132 meters. Used a Titleist 716AP2 9 iron with a Titleist Pro V1x ball. Both of the above were in official competitions and do have certifications from both golf clubs. Do not have photo's - lost it, however, uploaded the hole in one on the par 4.
