The automatic, self-leveling Spectra Precision
®
LL400HV Laser Level is the most rugged, long range
laser level available, tough enough to handle a wide variety of general construction and vertical
alignment applications. Even in harsh jobsite conditions, the LL400HV delivers consistently reliable and
highly accurate performance, enabling you to work faster and smarter.
The rugged LL400HV laser can withstand drops of up to one meter (three feet) onto concrete and
tripod tipovers up to 1.5 meters (ve feet). This strength, combined with full weatherproong and
dustproong, reduces downtime and lowers repair costs over the life of the product.
The LL400HV laser’s self-leveling capability and optional RC402N radio remote control result in
outstanding accuracy and ease of use. The advanced HL760 Digital Readout (DRO) receiver that
provides automatic Grade Match - connects different elevations and establishes a sloped reference
over unknown ground and eliminates time consuming manual slope adjustments, and PlaneLok
- automatically locks on to an existing elevation or vertical alignment point which eliminates all drift
or possibility of error due to improper calibration or weather, and the unique “Fingerprint” function -
receiver only accepts the beam from the laser it is paired with. The CR600 receiver is also an option
when a machine mounted display elevation is required.
