Specifications by configuration

Identifying the right model

• Titleist’s photo shows GT1 (red 1) on a silver bar across the sole, a single oval weight port below the bar, the loft (10.0) printed beside the hosel and no sliding weight track.

What to check before using the reference

• Titleist’s table gives GT1 its own lie row: 59° in the A1 SureFit hosel position for all three heads, where GT2, GT3 and GT4 list 58.5°.
• The page footnotes 44.5 in as the standard women’s length and 43.5 in as the junior/youth length; 45.5 in is the men’s standard.
• Titleist’s compare block lists the GT1 head at 460 cc.
