Spectra Precision LL1505C-14A Laser level Package with Deluxe CR700 Multi-Use Receiver - Alkaline Batteries

Versatile Rotating Laser System Built for Grade Work and Machine Applications

The Spectra Precision LL1505C-14A pairs the dependable LL1505C self-leveling rotating laser with the CR700 multi-use receiver — giving contractors a single kit that transitions effortlessly from grade rod work to machine mast mounting. Whether you're setting footing elevations, controlling cut depth on an excavator, or checking subgrade on a grading spread, this system delivers the range, accuracy, and flexibility professional crews demand on every job.

System Overview and Jobsite Applications

The LL1505C rotates a highly visible red beam up to 4,000 feet in diameter, covering large commercial sites, road base work, and agricultural grading with ease. The self-leveling compensator automatically levels the instrument within a ±5° range, getting you on grade faster with less setup time. The CR700 receiver's dual-sided display and audible indicator make it equally at home clamped to a grade rod for fine elevation work or mounted to a machine mast for cut-and-fill excavation. Running on standard D-cell alkaline batteries, this kit keeps operating costs low and eliminates the need for proprietary battery packs in remote field conditions.

Job Applications

Foundation and Footing Layout: Set the LL1505C on a tripod at a stable benchmark, dial in your grade elevation, and use the CR700 on a rod to shoot consistent footing heights across the entire foundation perimeter — even on large commercial pours where optical levels lose time.

Excavation Depth Control: Clamp the CR700 to your excavator stick or machine mast and let the audible and visual indicators guide your operator to exact cut depth. The 4,000-foot range keeps the laser relevant across the full reach of most excavation sites without moving the instrument.

Subgrade and Rough Grading: The single-axis manual slope function lets you dial in a designed drainage or road cross-slope so your blade or scraper operator hits grade consistently, reducing over-excavation and material waste.

Concrete Flatwork and Slab Pours: Run the CR700 on a grade rod or bull float rod during screeding operations to verify slab thickness and flatness in real time, catching high and low spots before the concrete sets.

Frequently Asked Questions

Can the CR700 receiver be used on an excavator or machine mast?

Yes. The CR700 is a multi-use receiver designed for both grade rod and machine mast applications. Its robust clamp system and dual-sided display make it practical for equipment mounting, and the audible alert helps operators work without needing line-of-sight to the display.

Does the LL1505C-14A support two-axis slope?

No. The LL1505C offers single-axis manual slope, adjustable from 0–10%. Contractors needing two-axis slope capability should consider the Spectra Precision LL500 or LL600 series.

What batteries does the LL1505C use, and how long do they last?

The LL1505C runs on three standard D-cell alkaline batteries, providing up to 100 hours of continuous operation. This eliminates reliance on proprietary rechargeable packs and makes field replacements straightforward on any jobsite.

Is the LL1505C-14A suitable for outdoor use in rain?

Yes. The LL1505C carries an IP66 rating, meaning it is fully protected against dust ingress and resistant to heavy water jets. It is built for professional outdoor use in typical construction weather conditions.
