Leica GDF111-1 Tribrach

The hysteresis of the Professional 3000 Series tribrachs amounts to a maximum of 3" (1.0 mgon).

The foot screws are maintenance free and have a larger diameter.

This allows for fine adjustments, even when wearing work gloves under difficult environmental conditions.

These tribrachs are suitable for non-motorised TPS instruments with angle accuracy from 5" to 7" and GNSS antenna stations as well as back-sights and control points.
