M18™ Red Exterior Dual Slope Rotary Laser Level Kit w/ Receiver & Remote

The Milwaukee M18 Red Exterior Dual Slope Rotary Laser Level (model 3704-21) is a cordless kit for leveling, aligning, and squaring on exterior jobsites. This kit pairs the rotary laser with a laser receiver and a remote control that duplicates the laser's on-tool display, so slope can be set and adjusted from a distance. It runs on the M18 battery system and fits all M18 batteries.

What it does well

• Holds 1/16" horizontal accuracy at 100 ft. and 1/8" vertical accuracy at 100 ft.
• Three rotation speeds — 600, 900, and 1200 RPM — plus low and high bump sensitivity modes
• Reinforced housing withstands a 1.5 m drop and a 2 m tripod tip, with IP66-rated protection against dust and water

Is this the right laser level for you?

This is a full exterior-grade kit for concrete, masonry, grading, and general leveling work where you need long-range detection and adjustable slope. If you already run M18 tools, it drops into your battery lineup and adds ONE-KEY tracking. Remote slope adjustment and automatic grade match on the receiver make it a strong fit for pros running slope work solo. Note the laser reads with the receiver at range; for accurate results outdoors the receiver is your primary readout.
