Pro Shot Alpha 
Automatic Laser Level 
The new Pro Shot Alpha is a high accuracy, long range laser level suited for the most demanding construction jobs: large building pads, commercial foundations, and grade checking over long distances. It offers 1 button automatic leveling in standard operating mode. It can also be used as a manual grade laser that self levels in the cross axis. When the instrument completes its initial leveling, its Elevation Alert program constantly monitors for disturbances that could affect accuracy. The Alpha is accurate to ±10 arc seconds (±.060 in @ 100 ft or ±1.5mm @ 30m), with a working diameter of 2000 ft (610m), and runs for more than 100 hours on 4 C alkaline batteries. A rugged ABS housing will enable the instrument to survive jobsite drops and provide years of reliable service. The laser diode, optics, and electronics are fully enclosed, and the unit is protected from dust and water ingress to an IP56 rating. A 2 year warranty against defects in workmanship and materials is standard.
