Callaway X Hot, X Hot Pro drivers
There is no mistaking what Callaway wanted to do when it made the 46-inch X Hot driver: maximize distance.
The 460-cc head is all titanium, and according to the company, it's the lightest all-titanium driver Callaway has ever made. While it does not have adjustable weights, the X Hot does have an adjustable hosel that allows players to set the clubface into three address positions: open, neutral or closed.
The face is slightly thicker in the center and thinner around the edges to expand the sweet spot in all directions and help golfers maintain ball speed on shots struck off-center.
To help golfers achieve the ideal ball flight, Callaway adjusted the center of gravity (CG) of the X Hot driver based on the loft of each head. The lower the loft, the more neutrally located the CG; higher lofted drivers have a CG that creates more of a draw bias because Callaway research showed that most players who need more loft fight a slice.
The all-titanium X Hot Pro driver has a deeper face than the X hot, has a 440-cc head and its shaft comes standard at 45.75 inches. It features the same adjustable hosel as the X Hot. All this should make it more appealing to fast-swing players who like to work the ball off the tee.
The X Hot comes standard with a Project X Velocity shaft, and the X Hot Pro comes with a Project X 6.0 shaft.
