Spectra Precision LL1505C-X1 Laser level Package with HL450 Receiver, TENTHS Rod, Tripod and Small Case - Rechargeable

The Spectra Precision LL1505C-X1 is a complete horizontal rotary laser package engineered for site contractors, utilities crews, and civil construction professionals who demand reliable, civil-grade accuracy across large jobsites. This factory-bundled kit pairs the rugged LL1505C rotary laser with the HL450 machine-mounted or hand-held receiver, a tenths-graduated measuring rod, a heavy-duty tripod, and a protective carrying case — everything you need to start working the moment you arrive on site.

Overview & Jobsite Applications

The LL1505C-X1 is built for professionals who can't afford downtime. Whether you're establishing grade on a subdivision, setting forms for a concrete pour, or coordinating drainage across a utility corridor, this package delivers the range, durability, and measurement precision that civil work demands. The 2,600-foot diameter working range covers the full footprint of most residential developments and light commercial sites, while the IP67-rated laser head withstands rain, dust, and accidental drops without skipping a beat.

Job Applications

Site Grading & Earthwork: Use the 2,600-ft range and HL450 receiver mounted to a grade rod or machine mast to establish and verify cut/fill grades across large pads and rough grading operations.

Concrete Formwork: Set the LL1505C on a tripod at a known elevation, then use the receiver and tenths rod to transfer grade to form pins and screeds with consistent accuracy across the slab footprint.

Drainage & Utility Layout: The tenths rod and receiver combination makes it straightforward to set pipe invert elevations and confirm drainage slopes along utility corridors and storm sewer runs.

Residential Foundation & Footing Work: Quickly level batterboards, set footing depths, and verify foundation elevations on residential builds without pulling a crew member off productive work to hold a rod.

Compatible Accessories

• Spectra HL760 Dual-Slope Receiver — upgrade for grade-matching on slopes

Frequently Asked Questions

Can the LL1505C-X1 be used outdoors in rain?

Yes. The LL1505C laser head carries an IP67 rating, meaning it is fully dust-tight and can withstand temporary submersion in up to 1 meter of water. It is designed to keep working through rain and muddy jobsite conditions without loss of accuracy.

Does the HL450 receiver work with machine control equipment?

The HL450 is compatible with clamp-mount setups on grade rods and machine masts, making it suitable for use with motor graders, dozers, and excavators equipped for manual grade indication. For full machine control automation, a dedicated machine control receiver system would be required.

How long does the rechargeable battery last on a single charge?

The LL1505C delivers up to 20 hours of run time on a full charge of the included NiMH battery pack. Actual run time will vary depending on rotation speed setting and ambient temperature, but a full charge is sufficient for multiple full workdays under normal conditions.

Is this package an authorized Spectra Precision kit, or is it third-party bundled?

The LL1505C-X1 is a factory-configured package from Spectra Precision and is sold by Express Tools as an authorized dealer. The kit includes a full manufacturer's warranty on all components, and warranty service is supported through Spectra Precision's authorized service network.
