Spectra Precision GL720 Dual Grade Laser Level

The Spectra Precision GL720 is a heavy-duty dual-grade laser level built for demanding grading, construction, and agricultural applications. It offers a grade range of ±10% on the X-axis and -0.5% to +25% on the Y-axis, making it suitable for complex slope and elevation tasks. With a servo deadband accuracy of 4.6 arc seconds and a grade resolution of 0.001%, the GL720 ensures ultra-precise results across job sites up to 900 meters (3,000 feet) in diameter.

This laser features self-leveling capability up to 25%, multiple rotation speeds (300, 600, 900 RPM), and a rugged waterproof housing for performance in all weather conditions. It runs on a 10Ah NiMH battery pack with up to 30 hours of operation, and is fully sealed to handle dirt, dust, and water.

Key Features:

• Dual Grade Range – ±10% (X-axis), -0.5% to +25% (Y-axis) for precision control on both slopes

• Exceptional Accuracy – ±1/32 inch at 100 feet (servo-controlled)

• Extended Working Range – Up to 900 meters (3,000 feet) diameter with a receiver

• Automatic Self-Leveling – Self-levels on both axes, even on steep grades

• Heavy-Duty Design – Waterproof, dustproof, and impact-resistant for extreme job site durability

• Long Battery Life – Up to 30 hours on a 10Ah NiMH pack

• High-Speed Rotation – Adjustable speeds: 300, 600, or 900 RPM
