Millimeter GPS precise positioning technology has been expanded into the paving industry, providing a 3D-GPS+ control system for pavers, profilers and trimmers.

• Lazer Zone technology generates a vertical accuracy to within a few millimeters
• PZL-1 zone-beam laser transmitter sweeps a 2,000-ft.-diameter area with a 33-ft.-high wall of laser light
• PZS-MC sensor mounted on mast attached to the toe arm of the paver
• Can also be used for setting stakes or checking grade behind the paver
