Tough, High Visibility, Versatile Interior
Construction Laser
The automatic, self-leveling Spectra Precision
®
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
300 series has been proven reliable in tens of
thousands of units sold and working throughout
the world.
