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.
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.
