Overview

The Spectra Precision LL300N-2 is a robust, self-leveling rotary laser kit designed for demanding job sites.

Designed to keep pace on busy days, this kit supports steady, one-person operation with a wide working range and flexible power options.

Rugged design and field-ready reliability

• ROBUS and drop-worthy protection: a hard hat rotor cage and tough housing guard the laser head against daily job-site knocks, including 3 ft (1 m) drops onto concrete and 5 ft (1.5 m) tip-overs on a tripod.
• SELF-LEVELING PRECISION: automatic leveling within ±5° and ±3/32 in accuracy at 100 ft, with a practical working diameter up to 1,650 ft when paired with the HL450 receiver.
• WEATHER AND DUST RESILIENCE: IP66 rating defends against dust and powerful water jets, plus an out-of-level alert that disables rotation if the unit is disturbed.

• EXTENDED RANGE: up to a 1,650 ft diameter operating circle with the included HL450 receiver.
