The DEWALT DW0892 line laser detector delivers precision accuracy for all your horizontal and vertical alignment applications. This line laser detector works over distances or in bright conditions, as it is able to detect the laser beam indoors and out. It provides great coverage and distance with an interior and exterior range of up to 165 feet. This unit offers front and rear back-lit LCD displays for easy viewing with selectable narrow and wide accuracy settings and an audible signal with adjustable volume control (high, low, mute). Automatic shutoff turns off the detector if it is inactive for 5 minutes to conserve battery life when not in use. The DW0892 also offers top mounted magnets which allow for attachment to ceiling track or steel studs, along with a quick-release clamp. This tool is compatible with: DW088K, DW089K, DW0811, DW0822, DW0851
