Advanced Green Beam Pipe Laser for Precision Gravity Line Installation
The Leica Piper 200G represents the current benchmark in pipe laser technology, combining green beam visibility, an integrated laser plumb reference, and Alignmaster target technology in a single system engineered for contractors who stake their reputation on accurate gravity pipe installation. This complete package includes the Piper 200G laser head, remote control, and Alignmaster target system—providing everything a crew needs to hit grade on day one and keep it there throughout the job.
Purpose-Built for Gravity Pipe Work
Whether you are laying municipal sewer mains, storm drainage systems, or site utility lines, the Piper 200G is designed around the demands of real trench conditions. The green beam laser diode produces a visible spot that is significantly easier to see in bright ambient light compared to conventional red beam units, reducing the chance of misreads and keeping production moving. The onboard laser plumb reference lets operators quickly establish vertical alignment at the manhole or inlet structure without setting up secondary instruments, saving time and eliminating potential setup error. The sealed, self-leveling head holds calibration across temperature swings and vibration from nearby machinery—conditions that push lesser instruments out of tolerance.

Job Applications
Municipal Sewer Main Installation: Set grade at the upstream manhole and drive the machine forward—the Alignmaster target keeps the crew on grade all the way to the next structure, with digital readout eliminating guesswork on deep, long runs.
Storm Drainage and Culvert Work: The wide ±10% grade range covers steep outfall lines and mild detention pond feeds alike, and the IP67 rating means the laser keeps working even when the trench takes on water.
Trenchless Bore Guidance: The integrated plumb reference and fine grade adjustment via remote make the Piper 200G a reliable guide head for short horizontal directional bores where pipe accuracy is critical from the start.
Site Utility Coordination: On congested commercial sites where multiple utility trades share trenches, the green beam's superior daylight visibility reduces the risk of crew misreads and grade errors during busy production days.

Frequently Asked Questions
- What is the difference between the Leica Piper 200 and the Piper 200G?
- The Piper 200G uses a green laser diode (532 nm) instead of the red diode found in the standard Piper 200. Green light is approximately four times more visible to the human eye under the same conditions, making it easier for crews to read the beam in bright daylight or when working with long sight lines. All other core specifications—grade range, accuracy, IP rating, and battery life—are essentially the same between the two models.
- Does the Piper 200G work in wet or flooded trench conditions?
- Yes. The Piper 200G carries an IP67 rating, meaning it is fully protected against dust ingress and can withstand temporary immersion in water up to 1 meter deep for 30 minutes. This makes it suitable for trench conditions where groundwater infiltration or rain accumulation is a concern during active pipe laying operations.
- How does the Alignmaster target improve accuracy compared to a standard bull's-eye target?
- The Leica Alignmaster is an electronic target that provides a digital readout of the laser's position relative to the pipe centerline, rather than requiring the operator to visually judge the beam's location on a passive target face. This eliminates interpretation error, speeds up grade verification checks, and allows for more consistent readings across different crew members and lighting conditions.
- Can the remote control adjust both grade and alignment from the trench?
- Yes. The included remote control allows the operator to fine-tune horizontal alignment and vertical grade settings directly from the pipe trench without returning to the laser head. This is particularly valuable on long runs or in confined trench conditions where repositioning the instrument frequently would slow production significantly.
