What is gear effect?
The most important features of fairway woods are getting the ball airborne and keeping it in play, whilst getting the distance you need.
You never know what kind of lie you're going to get off the tee - there could be no grass or high grass. In order to be able to deal with these conditions, the centre of gravity in a fairway wood needs to be low. If the centre of gravity of the head is lower than the centre of the ball, the club will launch the ball easily.
Gear effect is the rotation of the head around its centre of gravity, which imparts corrective spin to the ball.A persimmon head has a deep centre of gravity due to its construction, allowing the head to have more gear effect; when a shot is mis-hit off the toe, the ball spins counter clockwise and curves back into the fairway. The reverse happens on balls hit off the heel. This is the natural corrective action a persimmon head puts on the ball.
Does gear effect have an impact on distance?Distance with the club is dependent on the shaft length and the loft. A persimmon head with the same loft and shaft configuration will propel the ball as far as a head made from any other material.
Do metal woods have gear effect?
You can experience gear effect with a metal club, but the effect will be less than that of a persimmon wood.
Since the centre of gravity (COG) in a metal wood is very close to the face, there is less gear effect; so a metal driver launches the ball at a steeper trajectory at impact.
With the COG of a persimmon driver deeper in the head, the ball flight of a persimmon driver tends to be lower than a metal equivalent in the same loft. This deeper centre of gravity creates more gear effect, and the player is better able to work the ball. This is why our drivers are available in three lofts, to suit all swings. It also allows for greater correction on a mis-hit shot.
