Levelling bases
Tribrachs (leveling bases) are accessories used to precisely align surveying equipment such as GNSS antennas, total stations or prisms. They allow fine leveling adjustments via micrometric screws or locking levers, ensuring a stable alignment to the horizontal plane. Typically, they include a bubble level, locking screws and compatibility with various tripod formats. They are essential in tasks requiring high angular accuracy or long-term measurement stability.
