1 Building construction
2 Indoor and outdoor decoration
3 Brick-paving, tile-laying
4 Installation of fire control, air-conditioner, windows and doors etc.
5 Photo hanging
6 Applid in other industries with vertical and level benchmark
1 360 ° Rotary, fine adjustment.
2 If not level, it has beep alert.
3 Three AA batteries.
4 Position the auto laser line level at target position (on the floor, attached to a tripod or wall bracket, depends on your needs and situation)
5 On the spirit level- ensure the bubble is within target (bull's eye). It will auto-adjust the horizontal or vertical line to level as long as level gradient is within +/-2.5°.
6 When vertical level & horizontal level converged, a cross-line/perpendicular line will be obtained. User will then able to obtain 90° angle.
