Leica 746157 IR Remote Control for Leica Piper Pipe Lasers

The Leica 746157 infrared remote control keeps your pipeline crew productive by putting full laser control at the working face — up to 500 feet from the instrument head. Whether you're pulling grade through a long sewer run, setting invert in a tight manhole, or directing bore alignment underground, this 6-button remote eliminates the constant back-and-forth that burns time and introduces alignment errors. Designed exclusively for the Leica Piper 100 and Piper 200 pipe laser systems, the 746157 is a purpose-built field tool, not an afterthought accessory.

Overview and Jobsite Applications

On active pipeline jobs, every trip back to the laser head is a disruption — it means climbing out of the trench, interrupting the target operator, and risking instrument disturbance before the grade is set. The Leica 746157 solves this by giving the rod or target operator direct control over the Piper laser's critical functions without touching the instrument. The rugged IR remote transmits reliably in direct sunlight and dusty trench environments, making it a dependable tool on municipal sewer, storm drain, water main, and utility boring projects where precision and pace both matter.

Job Applications

Municipal Sewer and Storm Drain: Control invert grade from inside the pipe or at the receiving manhole without disturbing the laser setup. Ideal for HDPE, PVC, and concrete pipe runs where grade tolerances are tight and re-shoots are expensive.

Utility Boring and HDD Operations: Keep the instrument operator and the bore crew coordinated without radio chatter. The remote lets the crew at the bore face adjust laser alignment independently on long horizontal runs.

Water Main and Gravity Line Installation: On longer drives where the target operator is hundreds of feet from the laser head, the 746157 enables real-time grade corrections that keep the string line accurate without halting pipe placement.

Confined Space and Manhole Work: Eliminate the need to exit a confined space entry point to adjust the laser. The remote keeps the operator safely positioned at the work area while maintaining control of the instrument above.

Frequently Asked Questions

What pipe lasers is the Leica 746157 compatible with?

The 746157 is designed specifically for the Leica Piper 100 and Piper 200 pipe laser models. It is not cross-compatible with other Leica laser families such as the Rugby or Lino series.

What is the effective range of the 746157 remote control?

The 746157 transmits up to 500 feet (approximately 150 meters) under line-of-sight conditions. Performance may vary slightly in environments with heavy dust, smoke, or obstructions between the remote and the laser receiver.

Does the remote control all functions of the Piper laser or only some?

The 6-button keypad covers the primary operational functions of the Piper 100 and Piper 200, including grade and alignment adjustments. For full setup and calibration, direct access to the instrument head is still recommended.

Is the Leica 746157 sold with batteries included?

Battery configuration should be confirmed at time of purchase. We recommend contacting our team or referring to the Leica product documentation for battery specifications before deploying the remote on a jobsite.
