BOSCH GRL2000-40HVK REVOLVE2000 Self-Leveling Horizontal / Vertical Laser Package

Professional Rotary Laser Accuracy Straight Out of the Box

The Bosch GRL2000-40HVK Revolve2000 Complete Laser Kit is engineered for contractors who demand reliable, repeatable accuracy across demanding jobsite conditions. Whether you're establishing grade for a drainage system, laying out a foundation, or setting form elevations, this self-leveling rotary laser delivers ±1/8 inch at 100 feet accuracy and a working range of up to 2,000 feet in diameter with the included LR20 receiver. Every component needed for immediate, productive deployment is included — no separate accessory orders required.

Overview & Jobsite Applications

The Revolve2000 operates in full 360° horizontal rotation and vertical modes, making it equally capable on grade work, interior layout, and structural plumb checks. The laser self-levels within a ±5° range, reducing setup time on uneven terrain. An out-of-level alert with automatic shutdown protects measurement integrity — if the unit is disturbed, it stops and notifies the operator before a bad grade gets shot. The IP54-rated housing resists dust ingress and water spray, keeping the unit functional through typical outdoor construction conditions. Remote RC4 control lets a single operator adjust rotation speed, direction, and on/off status from up to 100 feet away without returning to the instrument.

Job Applications

Site Grading & Drainage: Set consistent slope and elevation benchmarks across large earthwork sites. The 2,000 ft working diameter keeps the instrument stationary through multiple grade checks without repositioning.

Foundation Layout: Use vertical mode to project reference planes for squaring walls, aligning anchor bolts, and checking structural plumb during concrete pours and block work.

Concrete Flatwork & Form Setting: Establish screed elevation references and confirm form heights quickly across slab pours. Variable rotation speed allows beam brightness adjustment for different lighting conditions.

Interior Ceiling & Partition Layout: Horizontal mode projects a level reference plane around an entire room, accelerating suspended ceiling grid installation, dropped soffit layout, and partition top-track alignment.

Frequently Asked Questions

Does the GRL2000-40HVK work outdoors in direct sunlight?

Yes. The included LR20 laser receiver is required for outdoor use in bright conditions. The receiver detects the laser beam electronically and provides audible and visual grade indicators, giving you reliable readings at distances up to 2,000 feet in diameter regardless of ambient light.

What is the self-leveling range and what happens if the unit is knocked out of level?

The Revolve2000 self-levels within a ±5° range automatically on startup. If the instrument is disturbed and pushed beyond that range during operation, the out-of-level alarm activates and the laser shuts down to prevent inaccurate readings from being shot by the crew.

Can one person operate the GRL2000-40HVK without a helper at the instrument?

Yes. The included RC4 remote control lets a single operator power the unit on and off, change rotation speed, and switch rotation direction from up to 100 feet away. This is particularly efficient on grading and flatwork operations where the rod person and instrument operator are the same individual.

What batteries does the GRL2000-40HVK use and how long do they last?

The laser head runs on four standard D-cell alkaline batteries, which are included in the kit. Battery life is rated up to 70 hours of continuous operation, making it practical to run through multiple full work days before a battery change is needed.
