Turnkey Laser System Built for the Jobsite
The Spectra Precision LL1505C-17 professional package is a fully matched, ready-to-work horizontal laser system designed for contractors who need accurate leveling and grade control without the hassle of sourcing individual components. Every piece in this kit is engineered to work together — from the LL1505C self-leveling rotating laser to the long-range HL760 detector, tenths-graduated grade rod, heavy-duty tripod, and rugged hard case. Add the rechargeable battery system and you have a complete solution that goes straight from the box to the jobsite.
System Overview & Jobsite Applications
The LL1505C is a professional-grade horizontal rotating laser built for demanding outdoor and indoor work. It self-levels quickly within a ±5° compensation range, giving you a reliable reference plane without manual adjustment. The HL760 receiver extends effective range up to 2,000 feet in diameter, making this kit equally capable on tight interior pours and sprawling site grading projects. Whether you're a general contractor, grading subcontractor, or civil crew, this system is sized and specified for real production work. The rechargeable power system keeps you running through full shifts without disposable battery costs.

Job Applications
Site Grading & Earthwork: Set grade stakes quickly across large sites. The 2,000 ft operating diameter means fewer instrument moves per day on commercial grading jobs.
Concrete Flatwork & Slab Pours: Use the HL760's on-grade signal to set screed rails and check pour elevation accurately across foundations and warehouse slabs.
Drainage & Utility Layout: Establish consistent fall grades for storm drain, sanitary sewer, and detention basin work where tenths-of-a-foot precision matters.
Building Layout & Interior Leveling: Transfer elevations for suspended ceilings, framing, mechanical equipment pads, and finish floor systems on multi-trade commercial projects.

Frequently Asked Questions
- Is this kit complete out of the box, or do I need to buy anything else?
- The LL1505C-17 package includes the laser, HL760 receiver, tenths grade rod, tripod, rechargeable battery pack with charger, and hard case. It is a turnkey system — no additional purchases are required to begin working.
- What is the effective range of this laser package?
- With the included HL760 receiver, the system operates up to 2,000 feet in diameter (1,000 ft radius) under normal outdoor conditions. Without a receiver, indoor visible range is typically up to 200 feet depending on ambient light.
- Is the LL1505C weatherproof enough for outdoor use?
- Yes. The LL1505C carries an IP66 rating, meaning it is fully protected against dust ingress and high-pressure water jets. It is designed to operate in rain, mud, and dusty site conditions across a temperature range of -4°F to 122°F.
- Can the LL1505C be used for vertical or interior applications?
- The LL1505C is a horizontal-only rotating laser. It is not designed for plumb or vertical plane work. For interior ceiling grid and wall layout requiring vertical planes, consider a cross-line or multi-plane laser in addition to this unit.
