Start training right with the NetKnight. A high-quality Smartphone controlled HOCKEY shooter tutor that allows players of all ages to practice in their driveway or on the ice. Great for any player that wants to fine tune their skills from beginner to expert. Using a SMARTPHONE the user can control how quickly the opening changes and even hold one spot open for as long as they want. This forces the shooter to always keep their eyes up while shooting, just like they need to in a game. This is a great tool/toy that allows everyone to have FUN while training.
