The Spectra Precision LT52G-2 is a professional-grade green beam point and line laser engineered for contractors who need reliable visibility across demanding indoor and outdoor jobsite conditions. The green beam is up to four times more visible to the human eye than a comparable red laser, letting roofing crews, framers, and concrete finishers stay productive even in bright ambient light. Bundled with the HR1220 laser receiver, this kit extends the system's effective working range well beyond what you can see with the naked eye, giving your crew the precision to work confidently at distance.
System Overview & Jobsite Applications
The LT52G-2 is built for contractors who move fast and need a layout tool that keeps pace. Its compact, impact-resistant housing handles the drops and vibration of active job sites, while the magnetic pivot base mounts securely to standard grade rods, tripods, and wall brackets. Whether you are setting door and window heights on a framing crew, scribing level lines for suspended ceilings, establishing reference grades across a concrete slab, or transferring points on a multi-story build, the LT52G-2 delivers consistent, accurate results without slowing down production.

Job Applications
Interior Framing & Partition Layout: Project a crisp green horizontal or vertical line across an entire bay without repositioning. Snap layout lines for non-load-bearing partitions, locate top and bottom plate positions, and confirm plumb on door openings in a single setup.
Ceiling Grid & Suspended Systems: Set a reference height for drop ceiling grids and light fixtures. The bright green beam remains clearly visible even when competing with fluorescent site lighting, reducing re-checks and rework for drywall and acoustical ceiling crews.
Concrete Flatwork & Grading: Use the HR1220 receiver outdoors to control screeding elevation across large slabs or to establish cut-and-fill grades. The 500 ft working diameter covers most pours and site grading operations without moving the instrument.
Plumb Transfer & Multi-Story Layout: The top and bottom plumb points allow accurate vertical transfer of control points between floors, making the LT52G-2 a practical tool for elevator shaft layouts, column centerlines, and curtain wall alignment.

Frequently Asked Questions
- Does the LT52G-2 self-level automatically?
- Yes. The LT52G-2 uses a pendulum-based self-leveling system that compensates for out-of-level conditions within ±4°. If the instrument is placed outside that range, it locks the beam and displays an out-of-level warning so you never unknowingly work from a tilted reference.
- How far does the HR1220 receiver extend the working range?
- With the HR1220 receiver, the effective working diameter extends to 500 ft (250 ft radius). This is significantly beyond naked-eye visibility and makes the kit suitable for outdoor slab pours, site grading, and any long-range layout task where the beam alone is insufficient.
- Can this laser be used outdoors in direct sunlight?
- The green beam offers substantially better visibility than red in sunlit conditions, but direct bright sunlight will still limit naked-eye visibility. For outdoor work in full sun, using the included HR1220 receiver is strongly recommended to maintain reliable detection at working distances.
- What is the battery life and what type of batteries does the LT52G-2 use?
- The LT52G-2 runs on 3 standard AA alkaline batteries and delivers up to 20 hours of continuous operation per set. AA batteries are readily available at any hardware or convenience store, so keeping a spare set on-site is easy and cost-effective.
