Word-of-the-Month: Cone Laser

Cone Laser

A cone laser is used to create the precise curved slope of a baseball or softball outfield. To make uniformed slopes, the laser is set in the center of the infield to create a level reference along a circle that intersects with the bases and home plate.

Beyond the infield reference circle, the cone laser is warped to slope down at a specified grade to the perimeter of the outfield. This laser guideline then controls the grading equipment during the shaping of the field, leaving a smooth, well-transitioned slope from the baselines to the outfield fence.

Fun Fact
Baseball and softball fields feature a sloped outfield to help prevent drainage from occurring in the infield. The slope of the outfield determines not only where drainage pools but also the field’s playability in damp weather.
