Bobby grace dct series has a full line of tour inspired shapes to fit any preference with the most modern science technology built in. dct stands for "distance control technology" and it is a first to market game improvement feature in all new bobby grace putters. dct is engineered to eliminate energy loss on off center ball contact. on a typical miss hit, 10 to 20% energy loss can occur to have a negative impact on the ball's carry distance and alignment control. in other words, a 40 foot miss hit putt will end up 4 to 6 feet short of the cup. with dct, energy loss (and therefore distance loss) is virtually eliminated. longer putts will feel like a tap-in instead of 5 footers.
