The Spectra Precision LL1505C-14 is the go-to rotary laser kit for contractors who demand rugged performance and reliable accuracy on demanding grade work. Pairing the proven LL1505C horizontal rotary laser with the feature-rich CR700 multi-use receiver, this kit delivers a massive 4,000-foot diameter working range and a rechargeable battery system that eliminates costly downtime from dead disposables. Whether you're grading a parking lot, setting footings, or establishing drainage slopes, the LL1505C-14 is engineered to take a beating and keep working.
Kit Overview & Jobsite Applications
Spectra Precision built the LL1505C for single-grade applications where consistency and durability are non-negotiable. The laser's IP66-rated housing shrugs off dust, rain, and jobsite abuse, while the self-leveling compensator gets you on grade fast without fussing with manual adjustments. The CR700 receiver extends usability in bright outdoor conditions and supports remote control operation so your rod man can fine-tune settings without walking back to the instrument. This kit is a workhorse on civil, concrete, and general construction sites of all sizes.

Job Applications
Parking Lot & Site Grading: The 4,000 ft working range covers large paving and grading layouts in a single setup, keeping your crew productive without repositioning the instrument.
Foundation & Footing Layout: Consistent horizontal reference at ±1/16 in. per 100 ft accuracy ensures your footing elevations stay dead-on across the entire slab footprint.
Drainage & Pipe Slope: Set manual grade slopes up to 25% along a single axis for precise invert elevations on storm drain and utility work.
Concrete Flatwork: Rotating at up to 600 RPM, the LL1505C gives screeding crews a continuous, fast-spinning reference plane for efficient slab pours.

Frequently Asked Questions
- Can the LL1505C-14 be used outdoors in bright sunlight?
- Yes. The included CR700 receiver is designed for outdoor use and can detect the laser beam at distances up to 2,000 ft in direct sunlight, making it highly effective even on bright, open job sites where the red beam is not visible to the naked eye.
- Does this kit support dual-grade applications?
- No. The LL1505C is a single-grade instrument, meaning it sets grade along one axis only. If your project requires simultaneous cross-slope control on both axes, consider the Spectra Precision LL500 or a comparable dual-grade model.
- How long does the rechargeable battery last on a full charge?
- The NiMH rechargeable battery pack provides up to 100 hours of runtime at standard rotation speeds. This is more than enough for full work weeks between charges and significantly reduces the ongoing cost of disposable batteries on long projects.
- Is the LL1505C-14 compatible with other Spectra Precision receivers?
- The LL1505C is compatible with most Spectra Precision and Trimble laser receivers, including the CR600 and CR700 series. The CR700 included in this kit adds remote control functionality for convenient receiver sensitivity adjustments from the rod without returning to the instrument.
