The GLS31 carbon‑fibre pole is a lightweight, high‑stability survey pole built from reinforced carbon fibre and equipped with a circular bubble for quick levelling and a twist‑lock mechanism for secure height adjustment.

Snap‑locks at 2.00 m, allowing fast and repeatable setup for GPS/GNSS antennas when used with the GAD31 adapter or the GRZ122 reflector. This makes it suitable for precision surveying tasks where rigidity, low weight, and consistent antenna height are essential.
