The 1‑metre carbon‑fibre extension pole is designed to attach securely to the lower end of the GLS51 AP reflector pole, providing additional reach without compromising rigidity or measurement stability.

This extension enables the use of tilt compensation at target heights above 3–4 m, making it suitable for high‑reach surveying tasks where maintaining precise geometry is essential.

It also supports height and depth measurements in confined or recessed locations such as manholes, drains, and access chambers, allowing surveyors to work safely from the surface while still achieving accurate results.
