The GL6x2 Range of Grade Lasers provide either single or dual grade capability in addition to being fully self-levelled in vertical for building axis alignment or setting 90 degree. Simple, robust and easy to use with a menu driven interface that is replicated on the radio remote control makes the GL612 (single grade) and GL622 (dual grade) the first choice for any contractor requiring grade capability.

Features and Benefits
- Multiple Applications - the Spectra Precision GL612N and GL622N provide the ability to control level, alignment, single grade /dual grade (GL622N only) and set 90 degrees.
- Automatic self-levelling - provides fast, easy set-up for horizontal level, grade or vertical alignment
- Automatic Grade Matching - meaning the laser moves to the on-grade position on the receiver automatically by communicating wirelessly with the receiver and the grade is then calculated – this is generally used when a constant fall is desired but the grade may not be known (renewing existing driveways or matching existing surfaces)
- Grade Range - Large, fully compensated grade range from -25% to 25% - keeping the laser levelled no matter what grade you need reducing errors and improving productivity.
- Anti-Vibration Filter - A laser can be affected by high vibration or strong wind, especially when the laser is mounted on a tall tripod –both the GL612N and GL622N have an anti-vibration filter that can be set according to the conditions allowing work to continue regardless of wind conditions or excessive vibrations.
- Temperature Compensation & PlaneLok- As temperature fluctuates throughout the working day, the internal components of a laser can expand and contract which can cause some additional error without the user noticing. This is can firstly be resolved through the automatic temperature check that the laser performs where the internal software calibrates the laser to its optimal performance based on the temperature. Additionally the PlaneLok function can be activated. This keeps the laser beam fixed to a receiver in a set position eliminating any error that can be caused by fluctuating temperatures, keeping the laser accurate and error-free.
- Automatic Axis Alignment - A critical factor when working with grade is alignment to the grade hub. If an alignment is off, error can be introduced and exaggerated. The GL622N has an Automatic Axis Alignment function, allowing the user to set-up simply and quickly, maintaining accuracy and eliminating costly errors.
- Rugged - the GL612N and GL622N can withstand a 1m (3 feet) drop directly onto concrete or 1.5m (5 feet) pushover on a tripod, eliminating costly repairs.
- Mask Mode - the GL612N and GL622N have a virtual masking function that allows the laser beam to be turned off on up to 3 sides, avoiding false readings from glass reflections or interfering with other lasers on the same job site.
- GL622IR Model - This model features an invisible infrared laser beam and is a Class 1 laser, the safest laser classification possible. This type of beam is required in special applications where a visible beam is a safety hazard, distracting or otherwise not permissible.
- Includes the advanced HL760 Digital Readout Receiver that can be used at an operating diameter of up to 800m (2,600 feet)
- Includes an RC602 radio remote control, which has a backlit graphic display and gives you full control of the laser from up to 330 feet away.
