The automatic, self-leveling Spectra Precision GL412N single grade laser is the most rugged, cost-effective lasers that do three jobs—level, grade, and vertical alignment. Even in harsh jobsite conditions, the GL412N delivers consistently reliable and accurate performance, enabling you to work faster and smarter.

The rugged GL412N laser can withstand drops of up to one meter (three feet) onto concrete and tripod tipovers up to 1.5 meters (five feet). This strength, combined with full weatherproofing and dustproofing, reduces downtime and lowers repair costs over the life of the product.

The GL412N laser system now includes the advanced HL760 Digital Readout (DRO) receiver that provides automatic Grade Match, PlaneLok and Fingerprint function.

Grade Match measures and displays the existing grade over unknown ground. As a consequence it eliminates time consuming and error prone calculations
PlaneLok automatically locks on to an existing horizontal elevation or vertical alignment point which eliminates all drift  or possibility of error due to improper calibration or weather.

The unique “Fingerprint” function only accepts the beam from the laser it is paired with. 
The CR700 receiver is also an option when a machine mounted display elevation is required.

Features & Benefits

  • Menu driven user interface reduces learning time and eliminates complex button pressing to activate advanced features
  • RC402N radio remote control allows control of all laser functions from up to 330feet (or 100 meters
  • Maintains performance even in rainy, dusty and other harsh job site and weather conditions - IP66 environmental rating
  • Durable design reduces downtime due to drops and tripod tipovers
  • Automatic Grade Match eliminates time consuming and error prone calculation
  • Mask mode eliminates interference with other crews on the jobsite
  • Comes with choice of CR700 or HL760 receivers so you can choose the best option to suit your application.


The all new Spectra Precision CR700 Laser Reciever has the same “light bar” technology that is included in the popular HL series of Spectra detectors and will deliver extremely accurate and more consistent results.

The CR700 step ahead in receiver technology! Its both Machine and Measuring Staff mountable.

The CR700 attaches to machines with the included new magnetic mount, which is 25% stronger than its predecessor (the CR600 magnetic mount), resulting in stable machine mounting and a reduction in errors.

With super bright directional LEDs, the CR700 is ideal for entry-level machine grade display, specifically on mini-excavators and backhoes. This provides instant grade information to the operator and eliminates the need for a rod man in the trench.

Aswell as the magnetic mount it also inlcuded the mounting bracket to attach it to measuring staffs.

For any application, the industry-leading 3 metre (10 ft) drop guarantee with 3-year warranty, confirm that the CR700 is the most reliable and robust laser detector available.

Spectra Precision digital readout detectors are simply the best laser receivers – without peers in accuracy, performance, reliability and warranty. The patented “light bar” technology provides more accurate and more consistent readings than traditional methods. This unique technology has fewer electronic components resulting in the most rugged and reliable laser detectors available on the market today.

The Digital readout allows you to set the readout to display in either milimeters or inches making this the perfect receiver for fast and accurate results.


Bright LED Arrow Displays – turn your head when you first turn on the CR700 because the new red/green/blue LED arrows are super bright and visible in all lighting conditions.

Magnetic Clamp – the new C71 magnetic clamp is 25% stronger than the CR600 magnetic clamp. It will not slip on the machine, no matter how rough the work is.

Light Bar Technology – patented laser reception technology delivers the most accurate, consistent and reliable performance.

Laser Radio Communication – the CR700 is radio-compatible with the GL400N / GL600N series grade lasers and the model HV302. This enables the use of time saving functions such as Grade Match, Fingerprinting, PlanLok and Axis Alignment.

IP67 – dustproof, waterproof, weatherproof.

3 metre (10ft) Drop Guarantee – almost destruction proof, extremely robust, eliminates downtime.

Digital Read-Out – the CR700 provides the exact distance from true level, numerically.

Remote Display – pair the CR700 detector with an HL760U detector and use as a remote display — very useful for machine operators and site supervisors.

"Fingerprint" On/Off – a menu function allows the CR700 to enable or disable Fingerprinting. This means it will only pick-up the red laser beam from your Rotary laser.

Backlight – to enable the User to view the laser detector in the dark.

Vertical Drift Alarm – when using lasers in vertical mode, after setting up your line, let the laser detector warn you if the laser has been disturbed.

3-Year Warranty – Competitors are not even close to covering 3 years on their laser detectors.
