• Dual grade with vertical versatility.
• The GL422N is a dual grade laser that also offers long-range operation in addition to its grade range up to 15%. 
• Operate the laser using longer range remote controls. 
• With a radio remote operating at a range up to 330 feet (100 meters) you have the ability to make grade changes and to make them remotely, which can significantly reduce setup time.

LOOKOUT!!!  It Takes a Licking and keeps on Winning 

• The GL422N laser can withstand drops of up to one meter (three feet) onto concrete and tripod tip-overs 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.
• Pairing the GL422N with the HL760 or CR700 receiver provides even greater functionality with the automatic Grade Match and PlaneLok features.
• Your Choice of Receiver:  HL760 or CR700

*HL760 Receiver Details:

• The HL760 Digital Readout Receiver is a highly versatile laser receiver for basic and advanced leveling and aligning applications.
• It is designed for general, concrete, and site preparation contractors.

Light Bar Technology HL760

• Spectra Precision's patented “Light Bar” technology has significant advantages.
• With “light bar” technology, laser detection resolution is nearly infinite, allowing greater accuracy and consistency.
• Fewer electronic components and connections are used.
• So “light bar” based products result in a more robust product.

Features & benefits of HL760

• Digital readout of elevation – no need to go to “on-grade” to measure; saves considerable time
• Large 12.7 cm (5 inches) reception height acquires the beam quickly and makes it easy to stay in the beam.
• Works with another HL760 or HL760U for long-range wireless remote display and monitoring – even when the second receiver is out of sight (up to 80 m or 260 ft.)
• Anti-strobe sensor stops construction strobe lights from setting off the receiver and makes it easier to identify true laser beam signals.
• Dust and weatherproof housing withstands a drop of up to 3 m (10 ft) onto concrete for reduced downtime
• Includes C70 rod clamp with bubble vial.
