Spectra Precision LL1505C-27A Laser level Package with HL760 Receiver, Rod INCHES, Tripod and Large SYSTEM Case

Step on the jobsite ready to work with the Spectra Precision LL1505C-27A complete rotary laser package. This all-in-one kit bundles the LL1505C self-leveling horizontal laser with the HL760 digital readout receiver, a graduated grade rod, a heavy-duty tripod, and a protective system case — everything your crew needs for foundation leveling, concrete flatwork, and site grading from day one. No sourcing extra components, no compatibility guesswork.

System Overview & Jobsite Applications

The LL1505C-27A is engineered for medium-range horizontal leveling tasks where consistent accuracy and fast setup are non-negotiable. The laser self-levels within its compensator range and begins rotating immediately, projecting a 360° horizontal reference plane across the worksite. Paired with the HL760 digital receiver, your rod person gets clear numeric grade readouts and audible signals, eliminating miscommunication between the instrument operator and the crew. Whether you are setting footings on a residential foundation, checking slab elevation across a commercial pour, or establishing drainage grades on a civil site, this system delivers the reliable reference plane to keep work on spec and on schedule.

Job Applications

Foundation & Footing Layout: Set the laser over a benchmark and sweep a consistent horizontal plane to verify form heights and bearing elevations across multiple footings — fast and without repeated instrument moves.

Concrete Slab Pours: Use the HL760 receiver on the grade rod to confirm subbase elevation and screed rail height before the truck rolls, catching high and low spots before they become costly corrections.

Site Grading & Drainage: Establish finished grade elevations across a pad or parking lot to verify positive drainage slope. The 2,000 ft working diameter covers most commercial lots in a single setup.

Utility & Pipeline Trenching: Drop the receiver into the trench and reference the laser plane to confirm invert elevations and maintain consistent pipe gradient throughout the run.

Frequently Asked Questions

Can the LL1505C-27A be used outdoors in direct sunlight?

Yes. The HL760 receiver is designed for outdoor use and detects the laser beam reliably in bright sunlight at distances up to 2,000 ft in diameter. The naked eye cannot see the beam in daylight, but the receiver picks it up without issue.

Does this package include everything I need to start leveling on day one?

Yes. The LL1505C-27A kit includes the laser, HL760 receiver, grade rod, tripod, and protective case. Add D-cell batteries and you are ready to work. No additional purchases are required to begin leveling operations.

What is the self-leveling range of the LL1505C?

The LL1505C compensator self-levels within ±5°. If the instrument is set up outside that range, it will alert the operator and stop rotating until properly leveled — preventing inaccurate reference planes from reaching the crew.

Is the LL1505C-27A authorized and warranted through Express Tools?

Yes. Express Tools is an authorized Spectra Precision dealer. All units are sold new with full manufacturer warranty coverage, and our team can assist with warranty service coordination if needed.
