The Spectra Precision LL300S-X22 is a complete, job-ready rotary laser level system engineered for contractors who demand precision, durability, and full-featured receiver performance on the most challenging jobsites. This deluxe kit pairs the proven LL300S self-leveling rotary laser with the HL760 deluxe digital receiver, a heavy-duty aluminum tripod, and an inch-graduated grade rod—everything you need to establish accurate reference elevations right out of the box. Whether you're pouring slabs, setting forms, or grading earthwork, the LL300S-X22 delivers the reliability and range professional crews require.
Built for Professional Jobsite Demands
The LL300S laser operates with a self-leveling range of ±5° and covers a working radius of up to 2,000 feet in diameter when used with the included HL760 receiver. Its sealed, weatherproof housing withstands dust, moisture, and the vibration common on active construction sites. The HL760 deluxe receiver elevates this kit above entry-level packages—its audible alarm and multi-segment LED display give operators clear, immediate grade confirmation, reducing the need for constant communication between the instrument operator and rod person. The heavy-duty tripod provides a rock-solid setup on uneven terrain, while the inch-graduated rod supports fast, accurate readings in standard field conditions.

Frequently Asked Questions
- What is the working range of the LL300S-X22 kit?
- The LL300S laser has a working diameter of up to 2,000 feet (approximately 610 meters) when paired with the included HL760 receiver. Unaided visible range is significantly shorter, so the receiver is essential for full working distance on large sites.
- Does the LL300S-X22 support manual grade applications?
- Yes. The LL300S supports manual grade settings on both single and dual axes, making it suitable for drainage slopes, ramps, and other grade-critical applications beyond simple level work.
- What makes the HL760 a "deluxe" receiver compared to standard options?
- The HL760 features both audible alarms and a multi-segment LED grade display, providing on-grade confirmation through sound and sight simultaneously. This is especially valuable in noisy environments like active pours or heavy equipment operations where visual-only feedback can be missed.
- Is the LL300S-X22 suitable for outdoor use in wet conditions?
- Yes. The LL300S laser is rated IP66, meaning it is fully protected against dust ingress and resistant to heavy water jets. It is designed for all-weather outdoor use on professional construction sites.
