The Contra core is the first to feature Durability Optimization Technology (DOT) – a patent-pending technology that creates an unrestricted drill area. 

Last Fall Brunswick introduced DynamiCore, an advancement in technology, creating a harder hitting and more durable bowling ball. This year we are excited to introduce another major advancement in bowling ball technology, DOT, Durability Optimization Technology. DOT is a patent-pending technology that has been developed to greatly reduce the widespread problem consumers face with their bowling balls cracking. We have included a video, a letter and marketing pieces to help you understand DOT better.
