Abstract

A level includes a laser source for establishing one or more visually identifiable measurement and reading in a work environment or in combination with the use of a power tool. A power tool control system includes a non-contact measurement and alignment device operative with the power tool and enabled to establish various readings, such as power tool settings. A graphical user interface communicatively coupled with the level and/or the non-contact measurement and alignment device enables user control over and display of the readings from the level and/or the non-contact measurement and alignment device.
