Spectra PrecisionSpectra Precision DG711 and DG511 waterproof pipe lasers withstand corrosion. They offer easy set up with a full range of mounting accessories. The controls are smart enough to tell you when they need maintenance. Both lasers are self-leveling and signal with a flashing beam when the initial setup line has been disturbed.
