LV1G automatic leveling level is a cross-hair laser, very easy to install and use, just turn it on and start working!
Using 1/4" threaded holes, you can use the LV1G with various fixtures and accessories (such as tripods). Two bright, right-angled laser lines provide horizontal and vertical light, which are perfect for alignment and leveling work.
With automatic leveling with visual level indication, LV1G is a great addition to any toolkit.
The LV1G also has a lock function, so you can press the top red button of the LV1G for about 3 seconds to get a tilted laser line if necessary.
