The vast majority of drivers on the market over the last few years have featured some degree of adjustability – the simplest form of which is the ability to adjust the loft of the club. In previous years manufactures made drivers with different stated lofts on them, 9, 10, 11-degree for example. However, the dawn of adjustable technology has allowed just one head to be made that can be set to any one of a selection of lofts – usually from 8 or 9 to 11 or 12 degrees, in half degree increments, with high lofts sending the ball higher off the club face and vice versa. This adjustment is made in the hosel of the club with a wrench that is supplied along with the driver.
Another adjustment made in the hosel is the lie angle. Usually directly linked to the loft adjustments (high loft, less lie angle and vice versa) and generally difficult to alter in metal woods and hybrids, club engineers at some manufacturers have devised a dual action hosel that allows lie angle to be altered independently from loft. Clubs that feature this will allow for more shot shape options than traditional loft only adjustment.
Before loft adjustment came moveable weight technology. This allows the user to move weight around the club head in order to move the centre of gravity and promote a different shot shape. This type of technology can take many different forms and is a favourite for the manufacturers as it is a way they can alter the launch and shot characteristics without altering the way the golf club is set up for loft and lie angle. For example, weight can be moved lower in the club to increase spin and launch angle without touching loft.
The combination of being able to alter loft, lie, and CG location can give the user a huge range of movement on their launch characteristics to help them find more fairways more often. Other types of adjustable technology are few and far between and are usually experiments that do not last more than a model.
