The is a no‑nonsense rotary laser receiver built to stretch your rotary laser’s working range up to about 200 m and keep your elevations true whether you’re inside or out. This isn’t a fancy gadget with a touchscreen — it’s a practical, truck‑ready measuring buddy that gives you clear visual and audible grade indications even when the sun’s beating down on the job.

It’s compact, powered off a single 9 V battery and rated with IP65 dust and splash protection, so it can take a beating and keep detecting your laser plane with an accuracy of ± 1 mm in fine mode and ± 3 mm in rough mode — and that matters a lot when you’re trying to hit tight tolerances on site or on a long grade run.

Key Features:

• 200 m Detection Range - Lets you pick up rotary laser beams far beyond what your eyes can see, ideal for big jobs.
• Dual‑Side LCD - Easy to read from either side so you can keep moving without twisting around.
• Visual and Audible Signals - Gives both sound and arrow feedback so you know when you’re on grade without squinting.
• Built‑in Magnets - Stick it to metal surfaces fast — great for ceiling grids or steel studs.
• IP65 Protection - Dust‑tight and splash‑protected so water and muck won’t kill it on the jobsite.

Applications
