Spectra Precision GL722IR Dual Grade Laser

GL722 Dual Grade Laser – Precision That Pays Off

The Spectra Precision GL722 is built for contractors who refuse to compromise. Tough, accurate and packed with intelligent automation, it delivers the performance you need to finish faster, cut rework and maximise productivity on every job.

Engineered with advanced temperature compensation, long‑life power options and crystal‑clear displays, the GL722 keeps your grade consistent and your workflow smooth — no matter the conditions. With better‑than‑5‑arc‑second accuracy, it’s the laser trusted for demanding applications where precision directly impacts profit.

Why the GL722 Stands Out

• Unmatched stability in changing temperatures
  Your grade stays accurate from the first cut to final compaction.

• All‑day runtime
  Flexible power options keep the laser working as long as your crew.

• Large, easy‑to‑read displays
  Clear visibility even when mounted high on a tripod.

• High‑precision performance
  Better than 5 arc seconds for the most demanding accuracy requirements.

Advanced Control. Smarter Workflow.

The GL722 includes a long‑range radio remote, giving you full control from anywhere on site. With Automatic Axis Alignment, Grade Match and PlaneLok, you get faster setup, tighter accuracy and reduced downtime — ideal for:

• General construction
• Site preparation
• Trenching
• Road construction
• Machine control

If you need a laser that keeps pace with high‑output crews, the GL722 is built for you.
