Complete Professional Rotating Laser System for Contractors
The Spectra Precision LL1505C-1A is a fully outfitted rotating laser level package built for contractors who demand accuracy, range, and reliability on every job. This kit bundles the proven LL1505C single-slope rotating laser transmitter with the HL450 digital numeric receiver, an Android-based smart remote control, a tenths-graduated grade rod, a heavy-duty aluminum tripod, and a large protective carrying case — everything you need to get to work from day one. With up to 2,600 feet of working diameter and rugged IP66 protection, this system performs in tough field conditions without hesitation.
System Overview & Jobsite Applications
The LL1505C-1A is engineered for horizontal leveling work across a wide range of general contractor and civil applications. The laser transmitter self-levels quickly within a ±5° compensator range, and the HL450 receiver gives you a clear numeric readout of cut/fill values in the field — no guesswork, no wasted time. The Android smart remote lets a single operator control grade, spin speed, and leveling functions from up to 200 feet away, dramatically reducing the need for a second crew member. Whether you're grading a parking lot or setting forms for a foundation, this package delivers the range and precision needed to keep your schedule.

Job Applications
Site Grading & Earthwork: The 2,600 ft working diameter gives equipment operators and grade checkers the range needed on large commercial grading sites. Set the laser at grade control elevation and let your crew work confidently across the entire pad.
Foundation & Footing Layout: Use the HL450 receiver's numeric display to set precise cut/fill depths when forming footings, piers, or slabs. The clear digital readout eliminates rod reading errors in fast-paced form work.
Drainage & Utility Work: Even though the LL1505C operates at 0% grade only, it excels as a reference elevation tool when trenching for drainage pipe, setting invert elevations, or checking finished grades after compaction.
Agricultural & Landscaping Leveling: The long battery life and wide working range make this laser equally capable on large agricultural leveling projects and commercial landscaping jobs where consistent elevation control across open terrain is essential.

Frequently Asked Questions
- Does the LL1505C-1A support dual-grade or slope applications?
- No — the LL1505C operates in horizontal mode only at 0% grade. If you need single or dual-slope capability for drainage or road work, consider upgrading to the Spectra Precision LL500 or HL700 series systems.
- What is the effective range of the HL450 receiver included in this package?
- The HL450 has a maximum working diameter of 2,600 feet (800 meters), matching the output of the LL1505C transmitter. It features a numeric digital display showing cut/fill values to help operators set grade quickly without manual rod reading.
- How does the Android smart remote work with the LL1505C?
- The RC402N Android remote pairs wirelessly with the LL1505C and allows one operator to adjust rotation speed, power the unit on or off, and monitor laser status from up to 200 feet away. This eliminates the need for a second crew member to manage the instrument during layout tasks.
- Is this package covered under a manufacturer warranty?
- Yes. The Spectra Precision LL1505C-1A is backed by Spectra Precision's standard manufacturer warranty. Express Tools is an authorized dealer, so your purchase is fully covered and eligible for factory service support. Contact us if you have questions about warranty registration or service.
