This red cross line laser from DEWALT projects bright crossing horizontal and vertical lines for various leveling and layout applications. This unit maintains full brightness for visibility and extends range. The full-time pulse mode allows for use with a detector. This unit features an over-molded housing and IP54 water/debris resistance and has an integrated magnetic pivoting base with 1/4" thread. When used with a detector, this laser can achieve up to a 165' range (detector sold separately).
