Tough, highly versatile General Construction Laser

The highly visible, multi-purpose Spectra Precision® Laser HV401 Horizontal Vertical Laser is an advanced laser with exceptional accuracy and durability for general construction projects. Replace the conventional method of stringlines and optical instruments—the HV401 gives you easy setup and one-person operation in a wide variety of commercial applications to increase accuracy, maximize your return on investment, and boost your productivity.

The HV401 is easy to set up, learn and use. A simple user interface common on the transmitter and remote control gives you automatic self-leveling and one-button operation. Designed for layout of excavation lines, aligning concrete forms, and performing as-built checks, the HV401 is your easy-to-use, economical choice for vertical alignment tasks.

The HV401 can be paired with the Spectra Precision Laser HR550 receiver for general construction applications or with the Spectra Precision Laser CR600 for additional machine control applications.
