The Hammer Vibe Emerald features a symmetric performance core and Hammer’s new Max-Length Pearl Reactive coverstock to provide excellent length with good backend reaction on medium to light oil lane conditions.
This is considered an Entry Level bowling ball, but that is a misnomer in our opinion. While many bowlers just learning to throw a finger tip hook might use this due to the price point, it also has a place in many high end bowler’s bags.
The Hammer Vibe Emerald has a polished coverstock and a bowlingball.com Perfect Scale rating of 122.5.
