DeWalt Introduces New Family of Self-Leveling Rotary Lasers
-- Lasers Provide Increased Durability, Accuracy, Visibility and Ease of Use --
July 2008 - DEWALT, a leading manufacturer of industrial power tools, announced the launch of its new family of self-leveling rotary lasers for interior and exterior use (DW074 and DW079) and exterior only use (DW078). The new lasers are ideal for trim carpenters, concrete workers, general contractors, deck builders, masons, and remodelers for applications including site leveling, excavation, post installation, concrete leveling, multi-level construction, block layout, benchmark and elevation leveling, and other interior and exterior applications.
Durability
For increased protection from jobsite hazards, the new self-leveling rotary lasers are built with a covered rotary head cage. DeWALT designed the head cage with multiple thin struts that surround the head in order to maintain durability and minimize blind spots. The DW078 and DW079 are equipped with an enclosed battery door that is dust and water resistant and allows users to easily remove batteries. Additionally, the DW078 and DW079 have a rubber over-molding that provides additional protection to critical laser areas when dropped.
Accuracy
The DW078 and DW079 are designed with an automatic horizontal self-leveling system that provides accuracy at plus or minus 1/8" per 100'. Easy to read X and Y LED lights flash while the laser is leveling. Once the unit is level, a solid LED beam will appear. As a way to further help to eliminate user error, DeWALT designed the DW078 and DW079 with a Hi-Alert feature that automatically turns the laser off to inform the user that the laser is no longer level with its original position.
The DW074 is designed with an automatic horizontal self-leveling system that provides accuracy at plus or minus 1/4" per 100'. Once the laser is turned on, it will begin to level itself and the laser dot will stop blinking when the unit is level. The DW074 is also equipped with a manual leveling feature for vertical mode that has electronic buttons for fast and accurate set up.
Visibility
The new rotary lasers are among the brightest in their class. The DW078 and DW079 are equipped with bright, sharp, high-powered beams that have a 2000' working diameter. The DW079 has a 5mW beam, which makes it the brightest Class IIIa beam in the market and is visible indoors up to 100'. Additionally, the DW079 has an easy-to-use scan mode button that displays a laser chalkline where the user needs it and can be easily controlled by the wireless remote or easy-to-use built in control panel.
The DW074 is equipped with a 2mW beam, which is the brightest beam available at this price point. The laser is visible indoors up to 100' and up to 1000' in diameter outdoors.
Ease of Use
Each model has a simple interface that starts with the power button. Once the lasers are turned on the DW074 and DW078 automatically begin leveling in horizontal mode, and the DW079 begins leveling in both horizontal or vertical mode.
Both the DW078 and DW079 are designed with enhanced remote control features that include a manual slope override system, which allows users to slope the laser and not the tripod when setting grades up to plus or minus five degrees. Both units have an on/off control that eliminates the need for users to have to walk back to the unit to reset the unit once it has been turned on at the base. Additionally, the DW079 remote control is equipped with a private mode to eliminate remote control interference between multiple users.
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 runtime.
