Durable, highly accurate Spectra Precision Laser LL400 Laser Level
withstands the toughest job site

The fully automatic, self-leveling Spectra Precision® Laser LL400 Laser Level sets a new standard in rugged reliability, handling a wide variety of general and concrete construction applications. Even in tough jobsite conditions, the LL400 consistently delivers reliable, accurate performance to increase your overall productivity and cost-savings.

The LL400 Laser Level features easy, one-button operation for basic leveling and provides reliable, highly accurate, long-range measurements, even for machine control applications.

The LL400 is designed to be durable and reliable, day in and day out, and can be operated in the rain for superior drop and weather protection. The rugged LL400 can withstand drops of up to 1 meter (3 feet) onto concrete and tripod tip-overs up to 1.5 meters (5 feet). This strength, combined with full weatherproofing and dust-proofing, results in reduced downtime and lower repair costs.

The LL400's self-leveling capability and optional RC601 remote control provide outstanding accuracy and allow one-person setup of slopes on grade.

Choice of Receiver

Choosing the right receiver ensures maximum performance from the LL400. You can customize the LL400 to your specific application needs with a choice of the HL700 or CR600 receivers.
