The ProShot™ Alpha C laser level has all the durability and performance of the standard Alpha, plus a custom-made precision cone rotor head. This unique, adjustable, cone projecting head lets you set-up with the laser at the high point, or low point and project a conical sloping reference of laser light. The Alpha C can project up to a 4% sloped cone either up or down, with increments of 1/4%.  An optional version provides up to a 1.7% sloped cone reference, with even greater resolution to 1/10%. The Alpha C is especially helpful for sports fields where a standard plane-only laser just won’t get the job done. Some specific applications include baseball fields, running track corners and their infield “D” zones and containment areas around storage tanks. The Alpha C can also operate as a precision laser level by installing the included level-only cap.
