Spectra Precision LL300N-2-PROMAG Laser Package with CR700 Receiver, Remote, INCHES-Rod and Tripod - Rechargeable

Every foundation pour, slab layout, and sitework cut starts the same way — with a reliable elevation reference you can trust across the entire jobsite. The Spectra Precision LL300N-2-PROMAG Laser Package gives you a complete, field-ready system built around the proven LL300N-2 rotary laser. This kit includes the CR700 digital grade receiver, RC703 wireless remote control, an inches-graduated grade rod, and a magnetic mount tripod with clamp. No sourcing components separately, no compatibility guesswork — everything works together out of the box.

System Overview & Jobsite Applications

The LL300N-2 self-leveling rotary laser is engineered for demanding horizontal and vertical grade work. With a 2,000-foot diameter working range and automatic self-leveling within ±5°, it locks in fast and stays reliable through vibration, temperature swings, and the general punishment of active job sites. The CR700 digital receiver extends usability in bright outdoor conditions where the naked eye can't catch the beam, delivering a clear digital readout of on-grade, high, and low indications. The RC703 remote handles all major functions — power, rotation speed, scan angle — so your rod person on the far end of a site doesn't have to walk back to make adjustments. Paired with a magnetic mount tripod and clamp, this kit is equally at home on a grade stake or steel column flange.

What's in the Kit

• LL300N-2 self-leveling rotary laser with Li-ion rechargeable battery
• CR700 digital grade receiver with rod clamp
• RC703 wireless remote control for full instrument operation
• Inches-graduated grade rod for direct elevation readings

Job Applications

Foundation & Slab Work: Set consistent elevation benchmarks around a full foundation perimeter. Use the magnetic tripod to mount directly to rebar or form steel without separate hardware.

Site Grading & Excavation: Establish cut and fill references across large open sites. The 2,000-ft working range keeps the laser stationary while your crew grades across the lot.

Concrete Flatwork & Screeding: Lock in a single elevation plane and use the CR700 to screed or strike off concrete to a consistent grade elevation without re-checking manually.

Structural & Vertical Column Alignment: The magnetic mount clamps directly to steel columns or beams, making plumb and elevation checks on structural steel fast and secure.

Frequently Asked Questions

Does the LL300N-2-PROMAG work in outdoor daylight conditions?

Yes. While the naked eye can't detect the beam in bright sunlight, the included CR700 digital receiver is designed for full outdoor use. It detects the laser beam at distances up to 2,000 feet in diameter and provides a clear digital display showing on-grade, high, and low readings regardless of ambient light.

Can the RC703 remote control all laser functions from a distance?

The RC703 remote controls the most frequently used field functions including power on/off, rotation speed, scan angle, and grade settings. It allows a single operator or rod person to make adjustments without returning to the instrument, which is especially valuable on large grading or flatwork sites.

What is the advantage of the magnetic mount tripod in this kit?

The magnetic mount tripod clamps directly to steel rebar, form hardware, columns, and structural members — no separate adapters required. This is particularly useful in concrete forming and steel erection applications where a standard tripod footprint isn't practical or where the instrument needs to be repositioned quickly.

Is this package compatible with grade matching or slope applications?

Yes. The LL300N-2 supports single-axis grade matching from 0% to ±25%, making it suitable for drainage, road base grading, and ADA-compliant flatwork where a consistent slope across a plane is required. Grade is set directly on the instrument or via the RC703 remote.
