The Fearless is the first ball to feature Brunswick’s new Durability Optimization Technology (DOT) system. This new manufacturing process moves the pin to the bottom of the ball from its traditional area around the CG. A small circle—the DOT—is then engraved on the ball 180 degrees from the pin, and this is the marking that is used in place of the pin for laying out the ball. This concept helps keep the holes away from the riser pin, which is a part of the ball that can be prone to cracking if weakened by holes in its vicinity. The Fearless—which also uses Brunswick’s DynamiCore filler material—comes with a four-year warranty, giving it the longest warranty in the industry. Besides the new pouring process, the Fearless uses the new Relentless solid reactive coverstock and a new symmetrical core called Contra.
