1,Electronic self-leveling, 2,wide leveling range, 3,high precision and stability Features and FunctionsHigh accuracy of automatic-leveling provided with an electronic sensorUnbalance warningAble to project four vertical lines, two horizontal lines and one plumb-down beam, thus to realize:        - Four cross-lines at right angle mutually        - One cross-line intersected on ceiling        - Plumb-down dot and the cross intersection dot on ceiling can together form one plumb beamThe instrument is 360°rotatable and also fine-adjustable in angleLaser-line flashing warning beyond automatic-leveling rangeSwitch-able between the continuous wave (CW) laser and the pulse laser, and compatible         for both indoor and outdoor purposesWide working distance with optional static detectorAble to connect with the tripod through the tribrach's 5/8" screw thread.Specifications:Laser wavelength: 635nmLaser class: Class II / IIIWorking range: ±33ft.
