I believe that bunker practice should be done in bunkers. Does Pocket Bunker really improve bunker play, and if so why?

We developed Pocket Bunker on the course, continually comparing the bunker shot with how Pocket Bunker performs on grass. That is why Pocket Bunker closely simulates bunker play. Pocket Bunker combines the elements found in a real bunker shot, including set-up, technique, feel and response from either a good or a bad shot. It does so consistently, allowing you to really focus on “missing the ball” consistently.
