Lucky you if you own a TSi driver with its incredible face produced by the Pittsburgh based Allegheny Technologies Incorporated, which is 425 Aerospace Titanium and is right on the USGA's CT and COR limits.

The Options

There are four different models in the Titleist TSi driver, and we've got a separate video explaining, in detail, the difference between them all. But for this page, in terms of their adjustability, they all come with Titleist's Sure-Fit hosel, which allows you to change the loft and lie settings to achieve your desired ball flight.

The Titleist TSi3 driver differs slightly as it also comes with Sure-Fit CG in the form of a perimeter weight track. This movement will significantly affect ball flight by moving 8-grams of mass from the centre to the heel or toe.

The Wrench

When you buy your Titleist TSi driver, it will come with a simple adjustment wrench, allowing you to remove the head, add or reduce loft, make the driver have a draw or fade bias, or move the 8-gram perimeter weight.

To open or loosen the screws, place the wrench into the top and turn anti-clockwise. To tighten a screw, turn it clockwise, and when fully tightened, there will be an audible "CLICK" to let you know the sleeve is safely locked in place and avoid over-tightening.

Titleist Sure-Fit Hosel: Applies to all Titleist TSi drivers

When the screw is fully open, you can remove the head from the shaft giving you access to the two rings which make up the Sure-Fit hosel. The top ring has letters, and the bottom ring has numbers.

These letters and numbers correspond to settings on the Titleist Sure-Fit chart, displaying all 16 different possible settings. You can raise the loft by up to 1.5 degrees or lower it by 0.75 degrees. You can also change the lie up to 1.5 degrees more upright or 0.75 degrees flatter.

Changing the settings

When the driver is assembled in the factory, it is set to the standard loft and lie position - A1. The Sure-Fit hosel allows you to increase or decrease the loft and change the lie setting to alter the draw or fade bias of the club.

If you're happy with the standard loft, but I want to make the club draw or move to the left(for a right-handed golfer), look left from position A1 on the chart. You'll see you need to find position A2, reattached the head, and you've got a driver with a draw bias.

If I wanted to hit the ball as high as possible and add as much draw as possible, you'd want to look up and left on the cart - position A3. Again, swivel the rings, line up the set with the dot and reattach.

Conversely, if you want to lower loft and add draw, you'll want to look down and left on the cart. That setting is position D2, and again, dial in the setting on the hosel and reattach.

The opposite is true for adding a fade (or left to right flight) on your drives. Look to the right on the Sure-Fit Chart from A1 to B1. For maximum loft and fade, it's B4 (up and right). And reducing loft with maximum fade, it would be position C1 (down and right).

Once you have the SureFit chart and identify on there what you want the ball to do, in terms of going high, low, draw or fade, it's really simple to choose whatever setting you like and takes seconds to change. And you can always switch back to standard position A1, so don't be afraid to experiment and play with all the settings.

Left Handed?

If you're left-handed, the Sure Fit system is different for you, but don't worry, we have you covered in a separate "How to adjust your LEFT HANDED Titleist driver" below.

Titleist Sure-Fit CG: Applies to TSi3 driver only

Where things start to differ is in the TSi3 driver. Titleist has moved away from the SureFit CG weight cartridge used in the previous TS3 driver to a new five-position rear track system. The weight cover assembly is made from a durable blend of polymer and carbon fibre, and it's so cleverly engineered that it blends seamlessly into the head.

Use the same wrench to loosen the cover, and with each turn, the cover rises up out of the head, allowing the 8-gram weight to become free to move. It's not necessary to altogether remove the cover to slide the weight.

Looking at the markings in the weight track, in the middle, there's N for Neutral, the default position for the weight. To the heel side of the driver, there are two settings, H1 and H2; think of them as Heel 1 and Heel 2. And towards the toe, there are two settings, T1 and T2, or Toe 1 and Toe 2.

Titleist is using H1 and 2, and T1 and 2 instead of Draw and Fade, which you might be used to from other drivers, but essentially they do the same job.

For instance, if you want to draw the ball or correct a slice, you can slide the weight to the H1 for a subtle correction or H2 for a more significant correction.

If you want to fade the ball or correct a hook, you do the opposite. Slide the weight to the T1 for a subtle correction or T2 for a more significant correction.

Once you've picked your setting from the five available, hold the weight in place and start to tighten the screw; wait for the "CLICK", and you're ready to go.

When and where?

Finally, it is very important to remember that you can adjust your driver on the range or at any time before or after your round, just not during it!
