Versatile Automatic Grade Lasers for Level, Grade and Vertical Alignment
The automatic, self-leveling Spectra Precision® GL412N single grade and
GL422N dual grade lasers are the most rugged, cost-effective lasers that
do three jobs - level, grade, and vertical alignment.
Even in harsh
jobsite conditions, the GL412N/GL422N delivers consistently reliable and
accurate performance, enabling you to work faster and smarter.
The rugged GL412N/GL422N lasers can withstand drops of up to 1 meter
(3 feet) onto concrete and tripod tipovers up to 1.5 meters (5 feet).
This strength, combined with full weatherproofing and dust-proofing,
reduces downtime and lowers repair costs over the life of the product.
Each GL412N and GL422N laser system now includes the advanced HL760
Digital Readout (DRO) receiver that provides automatic Grade Match -
measures and displays the existing grade over unknown ground and
eliminates time consuming and error prone calculations, and PlaneLok -
automatically locks on to an existing elevation or vertical alignment
point which eliminates all drift or possibility of error due to improper
calibration or weather, and the unique "Fingerprint" function -
receiver only accepts the beam from the laser it is paired with.
CR600 receiver is also an option when a machine mounted display
elevation is required.
Simplifies level, grade and vertical alignment setups
Increases reliability, accuracy and durability
Easy to transport, easy to carry, easy to store
Energy-efficient design offers long battery life
Highly durable design enables the GL412N/GL422N to survive a drop up to 1 m (3 feet) onto concrete
Radio remote control offers access to all laser function from every jobsite place
Leveling concrete forms and footers
General construction vertical alignment and plumb such as anchor bolt and form alignment
Grading and excavating
Concrete sections with runoff for sports fields, tennis courts and driveways
Steep slope road embankments and ditch banks
Parking garages, ramps and drainage
5 -Year “No Cost” Warranty Policy
The GL412N and the GL422N has a "5-Year – No Cost”- warranty that covers defects due to material and workmanship.
Spectra Precision Laser products with a “5-Year- No Cost” warranty
that have failed will be repaired AT NO CHARGE for five years from the
date of purchase.

*HL760 Digital Readout Receiver Overview:
Highly versatile receiver for basic and advanced leveling and aligning applications
Digital readout of elevation
Exact distance from on-grade displayed
Anti-strobe sensor to prevent false reading from jobsite strobe
Large reception height to ease beam reception
Withstands a drop of up to 3m (10ft)
Fingerprint functionality (when used with GL412N, GL422N, LL300S, LL400HV, and HV302) detects only the laser beam of the paired transmitter
*HL760 Features and Benefits:
Finger function filters out other lasers that strike the receiver and only accept the laser that it is paired with
No need to go “on-grade” to measure: saves considerable time
Reduces rework by allowing remote monitoring
Increases reliability, accuracy and durability
**CR600 Laser Machine Display Receiver Overview:
Comes with C51 Magnetic Mount - for when machine mounted display elevation is required
The CR600 Receiver is ideal for contractors doing both site prep and general construction.
The CR600 can be either rod or machine mounted, making it ideal for a wide range of applications.
Using the magnetic mount, the CR600 receiver is easily moved between
backhoes, small excavators, box blades or skid steer loaders.
With such a high degree of flexibility, the CR600 needs to be tough enough for any job.
**CR600 Features & Benefits:
Designed for tough construction site conditions.
Rugged, waterproof, lightweight magnesium housing can withstand a drop of up to 3 m (10 ft) on concrete.
Super-bright colored LED elevation indicators visibly indicate grade
elevation information to the operator even in poor light and up to 100 m
(350 ft) in bright sunlight.
Adjustable bandwidth lets the operator tighten the on-grade band to
easily meet a variety of accuracy requirements with tighter tolerances
from rough grading through form leveling.
Wraparound receiver cells with continuous pickup through an
operating range of 270 provide less dead spots and improved
productivity, especially for machine applications.
Longer, above-grade receiver cells make digging with a back hoe easier than ever.
Machine Applications: Site Prep, Building and Housing Pads, Sewage and Storm Drains.
Off-Machine Applications: General Construction
