Versatile Interior/Exterior Horizontal/Vertical Laser System Whether your job is indoors or outdoors, the automatic, self-leveling Spectra Precision® HV302 Horizontal/Vertical Laser is the most rugged laser available. It is tough enough to handle a wide variety of horizontal, vertical, and plumb applications. A split beam enables plumb point transfer and 90 degree layout. Even in brightly lit interior conditions, the high visibility beam delivers consistently reliable and accurate performance, enabling you to work faster and smarter. The rugged HV302 laser can withstand drops of up to 1 m (3 ft) onto concrete and tripod tip-overs up to 1.5 m (5 feet). This strength, combined with full weatherproofing and dustproofing, reduces downtime and lowers repair costs over the life of the product. Combine the HV302 with the advanced HL760 Digital Readout (DRO) receiver to provide Grade Match, PlaneLok and Fingerprint functions. Grade Match which connects different elevations and establishes a sloped reference over unknown ground. As a consequence, it eliminates time-consuming manual slope adjustments. PlaneLok automatically locks on to an existing horizontal elevation or provides quick automatic vertical alignment which eliminates all drift or possibility of error due to improper calibration or weather. The unique “Fingerprint” function of the HL760 only accepts the beam from the laser it is paired with. Different packages for interior, exterior or both ensure you have the right tool for your jobs.
