Seco 2.6 m Telescopic Aluminum Survey Pole – Dual Grad with External Metric Grad The Seco 5512-13-FLY-GM is a durable aluminum GNSS survey pole designed for flexible height configurations in field surveying applications. Its telescopic design extends to 2.6 m and features metric (cm) graduations with a zero height (0 H.T.) configuration for accurate and consistent measurements. This model uses a locking pin system with preset heights at 1.8 m, 2.0 m, 2.2 m, 2.4 m, and 2.6 m for repeatable setups. A built-in 40-minute vial supports quick leveling, and the pole can be adapted to additional heights using Quick Change Pole Height Adapters (2090-XX) .
