Columbia 300 is once again honoring its legacy with the return of a true fan favorite—the Pulse. Known for its smooth, reliable motion and benchmark performance, the original Pulse earned its reputation as a go-to ball for league bowlers and competitive players alike. Now, we’ve taken everything that made the original great and infused it with today’s technology to thrive on modern lane surfaces, oil patterns, and conditions. The updated Pulse offers the same predictable and controlled motion, but with a refined core and modern coverstock chemistry that allows it to handle today’s environments with ease. Whether you’re bowling on house shots or challenging patterns, the Pulse is that perfectly balanced symmetric that tells you exactly what the lane is giving you—a true benchmark you can trust, then and now.
