Designed for compatibility with Topcon®-style 360-degree prisms and remote controls, this essential accessory is perfect for Topcon-style robotic total stations. The pole extends from 4.90 to 8.60 feet (1.52 to 2.6m) and features a carbon fiber outer pole with dual graduation (0.01 ft/0.1 cm) and a black aluminum inner pole with dual graduation (0.01 ft/0.1 cm) for direct reading. The locking pin ensures a secure fit at various positions (5.5-ft to 8.5-ft), preventing slipping of pole sections. It comes with a 5/8-11 thread fixed male tip, a built-in 20-minute bubble vial, and a soft grip twist-lock knob for easy tightening and loosening of sections. The package includes the pole.
