Pure2Improve coach board volleyball. Use this double-sided Pure2Improve magnetic, dry-erase, coach-board to align your team and track your stats. One side includes a full court/field for diagramming plays, while the other side allows you to set up plays using the white and red round magnets, and allows you to track fouls, timeout, and matchups. This helps you to communicate better and faster what you want to make clear to your team. You can also write down key-points for everybody to remember. The coach-boards are made of lightweight plastic and include a whiteboard-marker (easy to erase) and magnets.
