The Spectra GL710 isn’t just a rotary laser — it’s a grading weapon built for serious dirt work. Whether you’re cutting slope for drainage, building large pads, or fine-tuning elevation across long distances, the GL710 delivers dead-on accuracy with the muscle to cover a 3,000 foot working diameter when paired with a receiver like the HL700 or CR600. Built for Big JobsWith a massive 1,500 foot working radius, the GL710 is made for road crews, utility runs, large sites, and anyone moving dirt across distances where most lasers fall short. Manual Slope MasterDial in single-axis slope from -0.5% to +25% with pinpoint control. The beam stays locked and stable even on rough terrain, so you don’t waste time chasing grade. Tank-Tough DurabilityJobsite-tested with a full aluminum housing and IP66 weather rating, the GL710 shrugs off rain, dust, drops, and daily abuse. It’s built to be thrown in the back of the truck and still perform. Laser-Guided AccuracyHolds ±1/16 inch at 100 feet, perfect for critical grade checks and layout. You’ll trust your numbers, not guess them. All-Day RuntimeGet up to 45 hours of continuous runtime on rechargeable batteries — or swap in alkaline D-cells for even longer life in remote locations. No Guesswork, No DowntimeSimple keypad setup, bright beam visibility, and variable rotation speed (300, 600, or 900 RPM) mean you can adapt quickly to changing site conditions and stay productive.
