Features & Benefits
	
GL412N / GL422N are grade plus horizontal and vertical lasers. Simple, accurate dial in grade from -10% to +15% (Single GL412N, Dual GL422N)
	
Up to 2,600 ft (800 m) working diameter which increases productivity by reducing need for multiple set-ups on a large job site
	
Fast setup, minimal training time and automatic self leveling minimize operating costs and boost productivity
	
Highly rugged design and patented lighthouse sealprotects the rotor head and glass andoffers superior drop and weather protection for reduced downtime
	
2-way full function remote control allows grade changes to be made from anywhere on the jobsite
	
Temperature calibrated for high accuracy over wide temperature changes
	
IP66 dust and water-proof to withstand harsh jobsite conditions
	
Customizable with choice of HL760, HR320 or CR600 receivers
	
Mask mode eliminates interference from other crews on the jobsite
	
Automatic Grade Match and PlaneLok
