Multipurpose Green Beam
Construction Laser for Interior
Applications

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.

The HV301G Laser Package includes:

• HV301G Laser

• 360-degree IR remote control

• Rechargeable NiMH batteries and charger

• Universal wall, floor, and tripod mount

• Enhanced ceiling target

• Green laser glasses

• Hard carrying case

Optional universal receivers are available.

Spectra Precision HV301G

Maximum Visibility and Versatility in Interior Construction Applications

HV301G Laser Features & Benefits

• High visibility green beam is four times more visible than standard red

beam lasers allowing you to work longer distances and in brighter
conditions

• Automatic self-leveling in horizontal and vertical applications assures

accuracy and quick setups

• Temperature compensation for accurate use throughout the day

• Intuitive, one-touch operator controls allow anyone to get to work quickly

• Adjustable rotation speeds and scanning zones position the beam

where it is needed

• Height of Instrument alert turns off laser and alerts the operator if
elevation is changed to avoid erroneous readings

• Remote control allows all functions to be carried out from anywhere
on the jobsite

• Flexible power options - efficient Nickel-Metal Hydride batteries are

standard; alkaline batteries can provide power backup

• Removable rotor cage for precise pointing and 360° coverage

• High durability design can withstand 3 ft (1m) drops onto concrete

reducing downtime and repair costs

• IP54 sealing allows work in all environments

• Built-in vertical stand and 5/8”×11” horizontal and vertical mounting

• Marking notches on each side of the unit provides operator fast

positioning over a point for plumb transfer

• Single axis manual slope mode to match known references

• Proven performance, ruggedness, and reliability with tens of thousands

of 300 series lasers in the field

• Choice of optional universal receivers for exterior leveling tasks
(works with visible green and red beam lasers and infrared lasers)
