Product Overview
The Milwaukee M18 Red Exterior Dual Slope Rotary Laser Level Kit with Receiver & Remote (3704-21) is designed for contractors who need accurate leveling, alignment, squaring, and grade work on demanding outdoor jobsites.
The dual-slope rotary laser combines precise horizontal and vertical leveling with remote slope adjustment, allowing users to make grade changes without repeatedly walking back to the laser. With the included receiver, the system provides a working range of up to 4,000 feet in diameter.
Built for construction environments, the laser features reinforced housing, 1.5-meter drop resistance, 2-meter tripod-tip resistance, and an IP66 rating. The included 3714 receiver adds Automatic Grade Match, strobe-light protection, and multiple accuracy settings for easier elevation work.
Key Features
Dual-Slope Rotary Laser
The 3704-21 is designed for more than basic leveling. Its dual-slope capability makes it suitable for establishing grades for applications such as drainage, excavation, concrete work, site preparation, and other outdoor layout tasks.
Remote Slope Adjustment
The included remote control duplicates the laser's display interface, allowing users to adjust slope remotely. This is particularly useful when the laser is positioned some distance away from the operator.
Accurate Leveling and Alignment
The laser provides:
1/16-inch horizontal accuracy at 100 feet
1/8-inch vertical accuracy at 100 feet
±5° self-leveling range
Horizontal and vertical self-leveling capability
These specifications make the laser suitable for establishing reliable reference points and elevations across a jobsite.
Up to 4,000-Foot Receiver Range
When used with the included 3714 Red Exterior Dual Slope Rotary Laser Receiver, the system can detect the laser at distances of up to 4,000 feet in diameter. This extended range is useful for large outdoor work areas.
Three Rotation Speeds
Users can select from 600, 900, or 1,200 RPM depending on the application. Multiple speed settings provide flexibility for different visibility and operating conditions.
Automatic Grade Match
The included 3714 receiver features Automatic Grade Match, which helps users quickly locate and match an existing grade. The receiver also provides five accuracy settings, with sensitivity down to ±1/32 inch.
Strobe-Light Protection
The receiver includes built-in strobe-light protection designed to reduce interference from other light sources on busy jobsites. This helps maintain a consistent receiver readout.
Built for Jobsite Conditions
The reinforced laser housing is designed to withstand drops of up to 1.5 meters, while the system is designed to withstand a 2-meter tripod tip. The laser carries an IP66 protection rating for resistance to dust and water exposure.

Remote Control
The included remote gives the operator access to the laser's interface without having to return to the laser itself. Its duplicated display allows users to make remote slope adjustments, making it easier to work with the laser when it is positioned away from the operator.
Milwaukee specifies a 328-foot receiver and remote communication range for the dual-slope rotary laser system.
Typical Applications
The Milwaukee 3704-21 is well suited for:
Site grading
Drainage layout
Excavation
Foundation preparation
Concrete and flatwork
Establishing elevations
Slope layout
Site preparation
Leveling
Alignment
Squaring
General outdoor construction layout
M18 Battery Compatibility
The rotary laser operates on Milwaukee's M18 battery platform and is compatible with M18 batteries. The kit includes an M18 REDLITHIUM XC battery and an M18/M12 multi-voltage charger, allowing the system to be used without purchasing a separate battery or charger.
The M18 platform also provides access to 200+ compatible solutions, making the included battery useful beyond the rotary laser.
ONE-KEY Compatibility
The 3704-21 is ONE-KEY compatible, allowing users to track and manage the tool's location through Milwaukee's connected tool-management system. This can be particularly useful for contractors managing equipment across multiple jobsites.
Jobsite Protection
The laser is designed for regular use in demanding construction environments and features:
Reinforced housing
1.5-meter drop resistance
2-meter tripod-tip resistance
IP66-rated laser protection
Low- and high-bump sensitivity modes
Strobe-light protection on the receiver
The receiver itself has an IP67 rating and is designed to withstand drops of up to 2 meters.
Important Model Difference
The 3704-21 is the receiver-and-remote kit. It does not include a tripod or grade rod.
If you need the same dual-slope laser system with a tripod and grade rod, the corresponding model is 3704-21T. Milwaukee's 3704-21T adds the 48-35-3700 rotary laser tripod and an 8-foot grade rod with feet and inch graduations.
