Spectra Precision LT52R-2 Point and Line Laser Tool - Rechargeable Batteries and HR1220 Receiver

Spectra Precision LT52R-2 Point Line Laser with HR1220 Receiver

The Spectra Precision LT52R-2 is a professional-grade point and line laser kit engineered for contractors who need reliable elevation control beyond the limits of a naked-eye beam. Paired with the HR1220 laser receiver, this kit dramatically extends usable working range and allows crews to maintain productivity in bright sunlight, high-bay interiors, and large open job sites where standard visible beams wash out. Whether you're managing grade on a parking structure, setting elevation benchmarks across a sprawling concrete floor, or controlling exterior drainage slopes, the LT52R-2 kit delivers the accuracy and range that demanding commercial work requires.

Overview & Jobsite Applications

The LT52R-2 combines versatile point and line projection modes with a pulsed beam output that pairs directly with the HR1220 receiver. The receiver extends detectable range to approximately 200 feet in diameter — far beyond what the eye can track in typical outdoor conditions. The laser's self-leveling mechanism automatically compensates for minor setup variations, locking the beam level within seconds so crews can focus on the work rather than the instrument. This kit ships with rechargeable batteries, reducing long-term operating costs on extended projects.

Job Applications

Large Floor Elevation Control: Set benchmarks across warehouse slabs, big-box retail floors, and distribution center pours where beam visibility is compromised by ambient lighting. The HR1220 receiver picks up the pulsed signal so rod operators can confirm grade at every station without line-of-sight to the laser head.

Parking Structure & Exterior Grade Work: Control drainage slopes and finished grade elevations on exposed concrete decks and parking lots. Bright outdoor conditions that render standard red beams invisible are no obstacle when the receiver is doing the detection work.

Elevation Transfer & Benchmarking: Transfer floor-to-floor or foundation elevations during framing and concrete phases on commercial construction. The point projection modes enable precise plumb and layout transfers in addition to horizontal elevation control.

Interior Fit-Out & MEP Rough-In: Use horizontal line mode to establish consistent ceiling heights, partition wall elevations, and MEP rough-in references across large open floor plates before walls are installed.

Frequently Asked Questions

Does the LT52R-2 work outdoors in bright sunlight?

The LT52R-2 produces a red beam that can be difficult to see with the naked eye in direct sunlight. However, when used with the included HR1220 receiver in pulsed mode, the kit is fully functional outdoors at ranges up to approximately 200 feet in diameter, making it practical for exterior grade and elevation work.

Is the HR1220 receiver included, or do I need to purchase it separately?

The HR1220 receiver is included in the LT52R-2 kit. You receive the laser, receiver with mounting clamp, rechargeable battery pack, charger, and carrying case as a complete ready-to-work system.

What type of tripod does the LT52R-2 require?

The LT52R-2 features a standard 5/8 in x 11 threaded base, compatible with the vast majority of contractor-grade survey tripods and laser stands available on the market. No proprietary mounting hardware is required.

Can the LT52R-2 project vertical lines or plumb points?

Yes. In addition to horizontal line mode used for elevation control, the LT52R-2 offers point and line projection modes that include vertical line and plumb point output, making it useful for partition layout, column alignment, and elevation transfer between floors.
