Dewalt announced three new self-leveling lasers for interior (DW074, DW079) and exterior use (DW078). Dewalt’s new lasers are built more durable with a covered rotary head case. The head cage uses thin struts which increases durability, but reduces blind spots. The outdoor lasers have a protective water resistant battery cover.
The DW078 and DW079 are designed with an automatic horizontal self-leveling system that provides accuracy at plus or minus 1/8” per 100’. The DW074 is designed with an automatic horizontal self-leveling system that provides accuracy at plus or minus 1/4” per 100’. One nice feature is the laser will automatically turn itself off if it is no longer level. At one point in time, we have all been working on a job site when something caused our laser to go out of level, (we are to busy in our work to do the right thing and constantly recheck the level accuracy), only to realize a little while later, things just don’t look right.
The DW078 and DW079 are powered by DEWALT 9.6V – 18V batteries that provide 30 hours of run time. The DW074 is powered by 2 “D” cells that provide more than 50 hours of run-time.
