Perfectly functional 2

The principle that this device is simple: a pendulum mounted a laser diode projects a level of cross on the wall. Operation is facilitated by a red LED on top of the device that lights up when the level is not correct and instinctive switch that off and hides the laser. It comes with a support that is essential and screws either in the device with a thread of 1/4-inch (standard picture) or using a clip-carrier equipped with the same thread, all in a big iron box cake painted in the colors of the brand. It is of course possible to project the inclined cross by tilting the camera but out of principle level. It greatly facilitates all operations of upgrades to the walls.
