With a working range of up to 2,600 feet, the Spectra LL400HV Self Leveling Laser is suitable for large construction projects and vertical alignment applications. This rotary laser features automatic Grade Match and PlaneLok capability The LL400HV is self-leveling horizontally and vertically within ±5 degrees and has an accuracy of ±1/16 inch per 100 feet. It features a single-axis slope mode that provides grade matching with self-leveling cross axis for improved accuracy. In addition, it has an out-of-level alert that shuts off the laser level if it is knocked out of place to avoid erroneous readings.
The optional Spectra RC402N remote control provides the ability to make grade changes and start automatic alignments from up to 330 feet away. It offers an easy to use menu-driven interface and features a backlit LCD with leveling indicators for easy viewing in low light conditions.
Combined with full weatherproofing and dustproofing, the LL400HV laser level enables construction professionals to operate in adverse environmental conditions. It can also survive drops of up to three feet onto concrete and tripod tip-overs up to five feet due to its metal sunshade and tough composite material housing. Using alkaline batteries, it works up to 60 hours of continuous use and up to 47 hours with the optional rechargeable batteries.
- LL400HV: With HL760 Laser Receiver and Alkaline Batteries
The Spectra HL760 enables the advanced functions of Grade Match and PlaneLok with wireless communication between the LL400HV and laser receiver. Grade Match slopes the laser automatically to match the fall between two elevations, while PlaneLok provides maximum stability and accuracy by automatically locking the beam on the receiver and keeping it on-grade. With a unique fingerprint function, the HL760 laser detector only accepts the beam from the laser it is paired with. This feature reduces errors and conflict between contractors working in close proximity with other laser levels. In addition, this Spectra laser receiver can be paired with another HL760 for a longer range wireless remote display and monitoring.

- LL400HV-10: With CR600 Laser Receiver and Alkaline Batteries
The Spectra CR600 laser receiver is ideal for long-range machine control applications. It has a 270-degree reception and magnetic mount for use on a backhoe, small excavator or skid steer. Rugged, accurate and easy to use, the CR600 provides high, low or on-grade information. With 15-channel linear display and receiver cells with continuous pickup, this laser detector provides less dead spot and does not require you to be on-grade to measure. The CR600 laser detector also has super-bright red and green LED elevation indicators, which ensure high visibility in poor or bright sunlight.
