LEICA TRIBRACH

GDF301, Tribrach without plummet: A cost effective tribrach suitable for use in normal environments. Suitable for all light-weight instruments of low angular accuracy. Black colour. Torsional stiffness <5", weight 800grams (1.76lb).

GDF302, Tribrach with optical plummet
A cost effective tribrach with optical plummet for use in normal environments. Suitable for GNSS
antennas. Torsional stiffness <5", weight 885grams (1.95lb).

GDF311, Tribrach without plummet: Suitable for TPS instruments with an angular accuracy of greater than 3". The footscrews have a large diameter which permits fine adjustment even when wearing work gloves. Torsional stiffness <3", weight 800grams (1.76lb).

GDF312, Tribrach with optical plummet
The tribrach and optical plummet are of robust construction and suitable for long period exposure in all environments. This makes the GDF312 ideal for GNSS and backsights and control points.
