Bosch GRL4000-80CHV 18V REVOLVE4000 Connected Red Rotary Laser Level Kit

The Bosch GRL4000-80CHV 18V REVOLVE4000 Rotary Laser Level Kit executes high-precision horizontal, vertical, and dual-axis slope layout for commercial excavation, concrete pours, and land grading. Capable of projecting up to a 4,000-foot working diameter with the included LR40 receiver, this instrument maintains +/- 1/16-inch leveling accuracy at 100 feet. Rated to IP68 water and dust ingress standards, the unit includes dual dial-in slope adjustment, Bluetooth app integration, and a CORE18V 4.0 Ah battery platform.

Best Used For:

  • Site Grading & Drainage: Setting dual-axis X and Y slope angles for run-off piping, roadbeds, and parking lot surfaces.
  • Foundation & Concrete Layout: Establishing level elevation benchmarks across expansive slab pours and footing forms.
  • Vertical Squaring & Plumb Alignment: Projecting 90-degree reference planes for curtain wall installation, structural steel, and interior framing.

Key Performance & Safety Features

  • 4,000-Foot Long-Range System: Long-distance red beam diode pairs with the LR40 receiver to cover large-scale commercial jobsites.
  • Dual Dial-In Slope Capability: Allows digital slope input on both X and Y axes directly from the interface or connected mobile app.
  • IP68 Environmental Protection: Submersible, dust-tight housing featuring heavy-duty rubber cage overmolding for harsh field durability.
  • Dual Power Architecture: Powered by an 18V CORE18V 4.0 Ah Li-ion battery or the included BA1 adapter using 4 D-cell alkaline batteries.
  • uCAL Calibration Guidance: On-board step-by-step user calibration sequence verifies tool accuracy without sending the unit to a service center.
  • Disturbance Monitor System: Automatically alerts operators and shuts down rotation if accidental tripod bumps alter height benchmarks.
