High Precision Base without Optical Lead (Seco)
High centering accuracy ± 0.5 mm at 1.5 m
The topographic base is an important accessory because it acts as an interface between the instrument and the support surface (tripod) and stabilizes it by blocking it. It therefore allows a stable and precise orientation.
This SECO base is compatible with all stations and GNSS 5/8 ''
You can choose between 2 versions: with or without optical plummet
Technical characteristics :
