The Plott PRL900HT-G is a professional-grade green beam rotary laser engineered for grading contractors, concrete flatwork crews, and excavation operators who demand visibility in full sunlight and the flexibility to dial in complex dual-axis slopes without leaving the cab or walking back to the instrument. Bluetooth app control, an 8% dual-slope range, and a 2,000-foot working diameter make this one of the most capable rotary lasers available under $1,000. The complete kit includes a machine-mount detector, wireless remote, and laser enhancement glasses — everything you need to get productive on day one.
Rotary Laser Built for Real Jobsite Conditions
Most rotary laser jobs fall apart in one of two places: you can't see the beam in bright conditions, or adjusting slope means walking back to the gun every time. The PRL900HT-G solves both. The green beam is up to four times more visible to the human eye than red in high-ambient light, and the Bluetooth interface lets you adjust grade, check tilt readings, and fine-tune settings directly from your phone or the included handheld remote. Whether you're cutting a parking lot, setting a slab elevation, or grading a retention pond, this instrument stays out of your way and keeps the work moving.

Job Applications
Grading and Site Prep: Set dual-axis slope across a full site and let machine operators work independently. Bluetooth control means grade adjustments happen from the seat, not from the tripod.
Concrete Flatwork: Pour slabs and flatwork to spec with consistent elevation reference across the entire pour area. Green beam cuts through concrete dust and morning glare where red struggles.
Drainage and Retention Grading: Dial in precise cross-slope and longitudinal slope simultaneously for parking lots, retention basins, and athletic fields where drainage tolerances are tight.
Excavation and Utility Work: Mount the detector on the excavator bucket or blade for real-time depth feedback. The IP54 rating handles the dust and splash that comes with trench and utility work.

Frequently Asked Questions
- Does the PRL900HT-G work with third-party detectors?
- The PRL900HT-G is optimized for the included Plott machine-mount detector, which is tuned to the instrument's green beam frequency and rotation speed. While some universal detectors may pick up the signal, Plott recommends using the included or factory-matched detector for reliable performance at full working range.
- Can I control slope settings from my phone?
- Yes. The PRL900HT-G connects via Bluetooth to the free Plott mobile app available for both iOS and Android. From the app you can adjust X and Y slope values, toggle rotation speed, lock the beam, and monitor instrument status — all without leaving your position on the jobsite.
- What is the maximum slope this laser can set?
- The PRL900HT-G supports dual-axis slope up to ±8% on both the X and Y axes simultaneously. That range covers the vast majority of grading, drainage, and concrete applications. For slopes beyond 8%, a manual slope laser or optical instrument would be required.
- Is this laser suitable for indoor use?
- Yes, though the PRL900HT-G is primarily designed for exterior and machine-grade applications. Indoors, the green beam is highly visible and the detector can be used on a grade rod for layout work. Rotation speed can be reduced to 150 RPM for slower scanning in enclosed spaces.
