The Spectra Precision LL1505C-82 is a contractor-grade, self-leveling rotary laser package built to handle demanding horizontal leveling and grading applications across large jobsites. This turnkey kit includes the LL1505C rotary laser, HR320 digital receiver, 16-foot grade rod, heavy-duty tripod, and a protective carrying case — everything you need to be fully operational the moment you step on site. Whether you're establishing finish grade, setting concrete forms, or checking drainage fall across a wide lot, the LL1505C-82 delivers the precision and range professional contractors depend on.
Overview & Jobsite Applications
The LL1505C is engineered for professionals who work on expansive sites where budget-grade lasers fall short. Its automatic self-leveling system locks in a true horizontal plane within seconds, eliminating time-consuming manual setup and reducing crew downtime. The included HR320 digital receiver extends usability in bright sunlight conditions where the unaided eye can't detect the beam, making this package a four-season, all-day workhorse. From residential foundations to large commercial grading operations, the LL1505C-82 adapts to the scope of work.

Job Applications
Site Grading & Earthwork: The 2,600-ft working diameter gives operators and machine operators consistent grade reference across full residential subdivisions or commercial pads without repositioning the instrument. Set it once and grade the entire site.
Concrete Formwork & Flatwork: Achieve accurate form height and slab elevation control with a single instrument setup. The LL1505C's ±1/16 in at 100 ft accuracy keeps concrete pours within spec and eliminates costly overages.
Drainage & Utility Layout: Use the laser and HR320 receiver to verify consistent fall on drainage swales, storm pipe inverts, and retention pond grading — critical work where elevation errors cause long-term performance problems.
Foundation & Footing Checks: Quickly confirm that footing elevations are consistent across an entire foundation perimeter, ensuring walls and slabs start on a true, level plane before framing begins.

Frequently Asked Questions
- Does the LL1505C-82 work outdoors in full sunlight?
- Yes. The included HR320 digital receiver is required for outdoor use in bright light conditions. It detects the laser beam at distances where the naked eye cannot, giving you reliable grade readings across the full 2,600-ft working diameter regardless of sunlight intensity.
- Is the LL1505C self-leveling, or does it require manual leveling?
- The LL1505C is fully automatic self-leveling within a ±5° range. Once you rough-level the instrument on the tripod using the adjustable legs, the internal compensator takes over and locks the laser plane level within seconds. If the instrument is disturbed beyond its leveling range, it shuts the beam off and alerts the operator.
- What is included in the LL1505C-82 package?
- The -82 package includes the LL1505C rotary laser, HR320 digital receiver with rod clamp, 16-foot fiberglass grade rod, a heavy-duty contractor tripod, a hard-shell carrying case, and batteries. It is a complete, ready-to-use leveling system with no additional purchases required to begin working.
- How long do the batteries last on the LL1505C?
- The LL1505C runs up to 65 hours on four standard AA alkaline batteries. This gives most crews multiple full work days of continuous use between battery changes, reducing the risk of downtime on active jobsites.
