Impact No. 3 CB

The Tommy Armour Impact No. 3 CB carries the No. 3 head shape into a counterbalanced build, a variant of the Impact line meant to shift weight and stability rather than change the fundamental profile golfers would recognize from the standard No. 3. According to golflink.com, the design purpose behind the counterbalancing is to stay more stable through the stroke, a rationale consistent with how counterbalanced putters are generally built across the category: added mass, often in the grip end or overall head weight, to quiet the hands and arms during the stroke.

golflink.com also lists the head weight at 400g, a notably heavy build relative to a conventional putter head. That figure lines up with the counterbalanced intent, since a heavier head paired with counterbalancing is a common way makers try to slow the stroke down and reduce manipulation from the hands.

Within the Impact line, the No. 3 CB reads as the counterbalanced answer to the standard No. 3, aimed at a golfer who wants the same head shape but a different swing feel. Golfers considering it against the standard No. 3 will want to weigh that reported 400g head weight and the stability-focused design purpose against their own stroke, since both figures here come from golflink.com's reporting rather than from Tommy Armour directly.
