PRODUCT DETAILS
The Mountlaser GLN-TRL500 Self-Leveling Rotary Laser Level is designed for construction professionals, contractors, and surveyors who need reliable leveling and alignment references on job sites. Its green laser beam provides good visibility, while the included receiver helps detect the laser signal over longer distances, including outdoor environments.
With automatic self-leveling, adjustable rotation speeds, scanning angles, and electronic dual-slope functionality, this rotary laser level supports a wide range of layout and grading tasks. The remote control allows users to adjust settings from a distance, helping reduce repeated trips to the instrument during fieldwork.
The unit features a standard 5/8"-11 tripod thread for compatibility with suitable tripods and mounting accessories.

Key Features
Green Beam for Outdoor Layout Work
The green laser beam offers strong visual visibility for positioning and alignment. For extended outdoor work, use the included receiver to detect the laser reference when the beam is difficult to see with the naked eye.
Automatic Self-Leveling
The automatic leveling system helps establish a level reference after setup within the instrument's specified leveling range. It reduces the need for repeated manual adjustments and supports efficient positioning on construction sites.
Adjustable Rotation and Scanning
Choose from three rotation speeds: 0, 300, 600, and 900 RPM are the listed settings for this model. Adjustable scanning angles allow users to focus the laser line on the working area.
Electronic Dual-Slope Function
The electronic dual-slope function supports slope settings of up to 5° on both the X and Y axes. Use the remote control to adjust the slope for grading, drainage installation, landscaping, and other applications requiring a controlled incline.
Remote Control and Quiet Operation
The included remote control allows convenient adjustment of instrument settings from a distance of up to 65 ft, according to the supplied product information. The belt-driven rotation mechanism is designed to reduce operating noise.
Convenient Mounting and Transport
The standard 5/8"-11 mounting thread fits compatible surveying and construction tripods. The carrying case helps protect the instrument and accessories during storage and transportation.
