Servo self leveling, high performance, rugged design. The Pro Shot™ Alpha construction laser level tool is designed for concrete and general contractors, working on large commercial or municipal sites.  The Alpha laser is built amazingly tough, to handle the real-world use and abuse that happens on sites with large crews. Electronic servo self leveling means you simply turn the laser on and it levels itself automatically. The Alpha also provides manual slope matching.
