Betteball Knockout Winners for 2014 This past weekend we had the final of the betterball knockout. The final was played by Renier Coetzee and Andre Watson vs Mike Meewes and Japie Venter. There wasn’t much to choose from the 2 pairings and at the end Renier and Andre emerged as champions off the 2014 Betterball Knockout.
Well done gents! | | |
Course News - Hollowtining The hollowtining of the greens went very well, the holes is only 8mm big so recovery time is much quicker then when you doing bigger holes. You will see when you play the ball still runs very smooth, the greens will be perfect again in no time, the height of cut is already on 3.5mm we will go down to 3.2mm in 1 weeks time.
After Tining | | After topdressing |
Our workshop manager Tokkos Joubert also built us a sweeper to brush in the sand after top dressing, the sweeper saved us a lot of time, also the labor was much less than using hand brooms, well done Tokkos. | | The sweeper in action on number 15 green |
Aerovator busy at number 18 | | We also Aerated all the tees, fairways, surrounds and semi rough areas, this will make a huge difference in these areas, the machine has vibrating pins that goes into the ground which breaks up the soil underneath, thus helping to relieve the compaction. Cultural practices is very important for the golf course, if you don’t do them it always comes back and bites you in the future. |
Special Birthday for Our Chairman – Vic Langkilde Ebotse Links Chairman and ex club captain, Vic Langkilde reaches another milestone of 65 on the 24th of January.
From all of us at the club, we wish you a very Happy Birthday! | | | Golf Digest Subscriber Challenge 2015 Ebotse Reciprocity – I would just like to give all our members an update again on the clubs that we have reciprocity agreements with in 2015. Reciprocity rates are in the region of R220pp, but are not the same at all the courses, so make sure to check when making a booking.
Elements Private Golf Reserve Woodhill Country Club Silver lakes Centurion Country Club Zebula Golf Estate & Spa Pinnacle Point Arabella Golf Club How Does COR Affect Your Golf Game? Companies, organizations and industries love to use acronyms, because these abbreviations of longer terms can so easily roll off the tongue. One that has been a buzz-acronym in the golf equipment industry since 1998 is COR – short for Coefficient of Restitution.
Experienced golfers know the COR is a number which represents how “hot” the face of their clubhead(s) is made – or rather how much distance they can get out of the shot for their swing speed. COR made its way into the golf industry’s vernacular back in 1998 when the United States Golf Association got freaked out at the distance the pros were hitting the ball. Acting before ever doing any testing, the USGA blamed the pros’ distance increase on the use of the relatively new (at that time) titanium drivers and enacted a rule that placed a limit on the COR of all driver faces. COR is actually a measurement of the energy transfer in a collision of two objects. It can be expressed in a number between 0 and 1. For example, when the USGA put a COR limit of 0.830 on driver faces, that meant no driver would be deemed to be conforming to the rules if more than 83% of the energy in the collision of the driver head with a golf ball were transferred from the head to the ball.

The COR rule also became known as the “spring face rule.” This was a little unfortunate because in fact, a higher COR clubface does not really act like a spring. When you think of spring face, it is easy to think that the ball causes the clubface to flex inward, and upon flexing back out the ball is propelled as in the manner of a trampoline sling shotting a gymnast up. Actually, higher COR faces work like this. In the collision of the clubface and the ball, there is always some energy lost. This is because the face flexes inward and the ball is compressed against the face. Both actions result in a loss of energy. Of the two, the ball loses by far the most energy when a shot is hit because it can squash as much as 30% of its diameter against the face of the driver. In a normal shot hit with an old thick face stainless steel metal wood, scientists estimate that 80% of the energy loss in such an impact came from the ball while the balance of 20% came from the clubhead.
The idea of a higher COR face design, whether done for a driver or any other clubhead, is to allow the face to flex inward a little more so that the ball is not compressed as much against the face. When that happens, the face loses a tiny bit more energy because of its increase in face flexing. But the ball then loses a lot less energy than before because it is compressed so much less because of the slight increase in face flexing.
The net result? The ball takes off at a higher velocity and flies farther for the same clubhead speed and same loft angle on the clubface. Hence high COR means more distance regardless of your clubhead speed.
And that’s how that acronym really works in the design and performance of a golf clubhead.
