A tactical board that helps you to illustrate your game on the lanes.

You can choose from a library of oil patterns (including WTBA patterns and Swedish league) and add it to the lane.
On top of the lane you can draw lines showing how the ball moved down the lane.
By choosing left or right handed and different color on the lines, you can easier see and illustrate the difference between players or multiple shots.

Examples:
Use it as a coach and show your bowlers how a lane has been played or how to attack the lane at the most efficient way.
Use it to teach new bowlers how to use different spare systems.
