Spectra Precision LL300N-1 Self-Leveling Rotary Laser Kit — IP66 Rugged Job-Site Performance

Rugged and precise leveleling for challenging job sites

The Spectra Precision LL300N-1 is a mid range, highly accurate self leveling rotary laser designed to thrive in demanding environments. Its rugged metal sunshade provides dependable protection from weather and impact, while an IP66 rating shields the unit from dust and heavy water jets. Built to withstand direct drops up to 3 feet (about 1 meter) onto concrete and capable of remaining field-ready if tipped over up to 5 feet (1.5 meters) on a tripod, this laser minimizes downtime and reduces potential repair costs over its life.

On site performance pairs precision with practicality. The LL300N self-levels within ±5 degrees and, when paired with the HL450 receiver, delivers about ±3/32 inch accuracy at 100 feet over a generous operating diameter of 1,650 feet. This combination makes it suitable for a wide range of leveling tasks, from establishing reference planes to translating rough elevations across rooms or exterior spaces.

The kit is purposefully field-ready. It includes the LL300N Laser Level, the HL450 Receiver with a C45 clamp, a Q104025 aluminum tripod, and the GR151 grade rod in tenths. Rounding out the package are four D-cell alkaline batteries and a system carrying case, so you can take the tool from truck to trench with minimal setup time. The product line emphasizes longevity and reliability, reflecting Spectra Precision decades of experience in precision measurement.
