Bosch LR40 2,000-Foot Red-Beam Rotary Laser Receiver with Dual-Sided LCD

The Bosch LR40 Rotary Laser Receiver extends the detection range of red-beam rotary lasers up to a massive 2,000-foot diameter for commercial site layout, excavation grading, and foundation leveling. Engineered with dual-sided backlit LCD screens and high-visibility LED indicator arrays, this heavy-duty laser detector provides clear visual and adjustable audio readouts across bright outdoor jobsites. Integrated X and Y-axes electronic buttons enable rapid cut-and-fill elevation calculations up to plus or minus 8.5 degrees, while rare-earth mounting magnets and a secure rod bracket ensure stable attachment to grade rods and metal framing.

Best Used For:

  • Site Preparation & Mass Excavation Grading: Tracking laser reference planes across 2,000-foot expanses to verify sub-base elevations and earthmoving depths.
  • Foundation Formwork & Concrete Pouring: Setting precise level marks on footing forms, anchor bolt assemblies, and poured concrete slab edges.
  • Commercial Steel Erection & Framing: Mounting the receiver magnetically to structural steel columns to establish consistent elevation benchmarks.

Key Performance & Safety Features

  • 2,000-Foot Diameter Working Range: Amplifies red-beam rotary laser signals to capture elevation lines over long-distance jobsite setups.
  • Dual-Sided Backlit LCD Screens: Front and rear digital displays and LED indicators provide simultaneous line-of-sight viewing from any angle.
  • X and Y-Axes Cut-and-Fill Controls: Dedicated keypad buttons allow technicians to calculate elevation differentials instantly without resetting the laser.
  • Oversized Center Detection Window: Large optical sensing area locates laser beams rapidly to minimize setup and calibration time.
  • Adjustable Audio Pitch Indicators: High, low, and mute audio tones signal on-grade positioning above roaring machinery noise.
  • Heavy-Duty Magnetic Mounting: Integrated rare-earth magnets and included mechanical rod bracket lock securely onto steel beams and leveling staffs.

What's Included

  • (1) Bosch LR40 Red-Beam Rotary Laser Receiver
  • (1) Heavy-Duty Rod Mounting Bracket
  • (2) AA Alkaline Batteries
