Spectra Precision LL300S-X2 PRO Laser Package - Rechargeable, HL450 Receiver, Remote, INCHES-Rod, HD Tripod and Small Case

The Spectra Precision LL300S-X2-PRO is a complete professional-grade rotary laser package assembled for contractors and survey crews who work in fractional-inch measurements. Built around the proven LL300S red-beam rotary laser, this kit pairs the instrument with an HL450 machine control receiver, RC wireless remote, an inch-graduated grade rod, a heavy-duty tripod, and rechargeable battery packs — delivering every tool a grading team needs to get on grade faster and stay there all day.

Package Overview & Jobsite Applications

The LL300S-X2-PRO is engineered for high-productivity outdoor grading, site preparation, drainage layout, and foundation work. The inch-scaled rod graduations make this configuration the natural choice for crews whose workflows, client deliverables, and training programs are built around fractional-inch increments rather than metric or tenths-of-a-foot readings. Whether you are setting cut-and-fill stakes on a commercial pad or checking finish grade on a residential lot, this package provides the accuracy, range, and wireless control to keep the job moving.

• Padded Carry Case: Organized storage and transport protection for all kit components

Job Applications

Site Grading & Earthwork: Set and verify cut-and-fill elevations across large commercial pads, parking lots, and subdivision lots using the HL450 receiver mounted to a grade rod or machine mast.

Drainage & Slope Control: Use single- or dual-axis grade mode to establish precise positive drainage slopes on driveways, athletic fields, retention basins, and landscape grading projects.

Foundation Layout: Transfer and confirm finished floor and footing elevations with inch-scale accuracy, reducing re-work and keeping concrete pours on schedule.

Utility Trench & Pipe Grade: Mount the HL450 to a grade rod inside the trench to set consistent invert elevations for storm drain, sanitary sewer, and irrigation piping runs.

Frequently Asked Questions

What is the difference between the LL300S-X2-PRO and the LL300S-X1 package?

Both packages are built around the same LL300S laser instrument. The X2-PRO differs by including an inch-graduated grade rod instead of a metric or tenths-scaled rod, making it the preferred configuration for U.S. contractors who measure in fractional inches. All other components — receiver, remote, tripod, and batteries — are equivalent across both packages.

Can the LL300S set grade on two axes at the same time?

Yes. The LL300S supports dual-axis grade mode, allowing you to dial in independent slope percentages on both the X and Y axes simultaneously. This is particularly useful for parking lot drainage design, athletic field crowning, and any application requiring compound slopes.

How far does the RC wireless remote control work?

The RC remote operates at a range of up to approximately 300 feet (90 meters) from the laser, allowing a single operator to adjust rotation speed, grade percentage, and scan angle from the rod location without walking back to the instrument.

Is the LL300S-X2-PRO suitable for machine control applications?

The included HL450 receiver is compatible with excavator and motor grader mast mounting for basic indicate-only machine applications. For fully automated blade or bucket control, a dedicated machine control system and compatible grade control receiver would be required.
