The automatic, self-leveling Spectra Precision Laser HV301G offers exceptional versatility and superior green beam visibility for increased productivity at a great value. The HV301G laser handles a wide variety of horizontal, vertical and plumb applications.

The HV301G green laser beam is easy to see in all interior jobsite conditions. The superior visibility of the green beam is useful for extended ranges or in bright conditions. The beam stays visible for efficient work in less than ideal conditions.

The HV301G laser transmitter sends a continuous, self-leveled 360-degree laser reference over the entire work area. Various rotation speeds and scanning angles allow you to concentrate the laser beam in your work area for optimum visibility.A 90-degree reference beam is included for a wide variety of layout work and point transfer. A 360 degree remote control allows operation of key functions over the jobsite.

Designed to be used by any contractor, the HV301G laser is easy to set up and use. Intuitive controls allow operators to carry out many functions with simple “one-touch” commands.

Electronic automatic self-leveling in both horizontal and vertical modes assure accuracy. A height of instrument alert turns the beam off when the elevation of the laser changes or is disturbed. The laser can also be used in the manual leveling mode for slope applications such as matching existing ceiling slopes.

Vertical applications are as easy to set up as horizontal applications. No additional vertical mounting brackets or trivets are necessary. Simply setup the laser on the built-in no-slip rubber footpads or mount vertically to a tripod with the built-in tripod mount.

The HV301G is rugged enough for the toughest jobsite. Highly durable construction enables the HV301G laser to survive a drop of up to 3 feet (1 meter) onto concrete. IP54 sealing assures the laser is unaffected by dust or moisture.

The performance of the Spectra Precision Laser 300 series has been proven reliable in tens of thousands of units sold and working throughout the world.
