Seco 2.5 m Telescopic Carbon Fiber Rover Pole - Dual Grad The Seco 5129-50 is a lightweight carbon fiber GNSS rover pole designed for kinematic surveying applications. Its telescopic design extends from 1.4 m to 2.5 m, with dual graduations (ft/metric) and a zero height (0 H.T.) configuration for flexible field use. This model features a TLV™ twist-lock system with integrated 40-minute vial for secure locking and quick leveling. A pin-lock system allows the pole to be set at fixed heights of 1.8 m, 2.0 m, and 2.2 m , ensuring consistent and repeatable measurements.
