PRODUCT OVERVIEW

Product Description

The Spectra Precision LL300N-X2 is a contractor-grade rotary laser kit built for crews who need dependable single-grade performance on demanding job sites. Combining the field-proven LL300N laser head with an inches-graduated grade rod and a heavy-duty HD tripod, this package gives you everything required to hit the ground running on grading, drainage, and foundation layout work. Whether you're setting cut-and-fill stakes on a commercial pad or fine-grading for a residential slab, the LL300N-X2 delivers the accuracy and durability that professional contractors rely on every day.

Built for Real Job Sites

The LL300N-X2 is at home on a wide range of civil and residential construction tasks. Its 300-meter operating range covers large pads, parking lots, and open grading areas without repositioning. The automatic self-leveling system compensates within a 15-meter range on most uneven ground, getting you set up fast even when terrain is less than ideal. The rugged housing is designed to withstand the vibration, dust, and moisture exposure that come standard on any active site. Because this kit ships with an inches-graduated rod, it integrates directly into imperial workflows without any unit conversion—ideal for U.S.-based crews working in feet and inches.

Frequently Asked Questions

Does the LL300N-X2 work outdoors in direct sunlight?: The LL300N uses a visible red beam, which can be difficult to see with the naked eye in bright sunlight. For outdoor use, pair it with a compatible laser detector such as the Spectra HR320 or HL760, which picks up the beam at full operating range regardless of ambient light conditions.
Can I use the LL300N-X2 for slope or grade work?: The LL300N is a single-grade laser, meaning the beam rotates on a self-leveled horizontal plane. It does not project a sloped plane natively. For applications requiring a set percentage grade (such as a pitched parking lot or sloped slab), you would need a dual-grade laser such as the Spectra LL500.
What batteries does the LL300N use, and how long do they last?: The LL300N runs on standard D-cell batteries, which are available at any hardware or big-box store—no proprietary packs required. Battery life is rated at up to 100 hours under normal operating conditions, making this one of the longest-running rotary lasers in its class.
Is the LL300N-X2 covered by a warranty?: Spectra Precision backs the LL300N with a standard manufacturer's warranty covering defects in materials and workmanship. As an authorized Spectra Precision dealer, Express Tools supports warranty claims and service coordination. Contact our team for current warranty terms and service center information.

Why This Equipment

Auto Self-Leveling

Compensates for job site movement and setups — no manual leveling required.

Long Range

Reach 2,600+ ft with a receiver — covers large pads and site-wide grading without moving.

IP55+ Protection

Dust-tight and water jet resistant — built for outdoor construction in any weather.

Radio Remote

Change grade or elevation from the cab or anywhere on site without walking back.

Why Buy This?

The right rotary laser pays for itself in weeks.

A grade checker costs $600–800 per day. A quality rotary laser setup eliminates that cost indefinitely — and works faster. One operator with a good laser and receiver can cover ground that used to take a two-person crew.

The gap between a budget unit and a professional-grade one shows up in the field: self-leveling range on uneven pads, IP55+ protection through rain and dust, and radio remote control so you're not walking back to the instrument every time the job moves.

Express Tools is an authorized dealer with genuine, factory-fresh inventory and same-day shipping on in-stock units. We know this equipment and can answer spec questions before you order.
