VEKTOR Basis with full intergrated prism

Available in pure carbon fiber (CFK) or carbon fiber/glass fiber hybrid fabric GFK/CFK with inserts made of aluminum or stainless steel.
The two high-quality glass prisms in a robust aluminum housing and the synchro tilt mechanism are fully integrated into the pipe and therefore well protected. For the highest accuracy, we recommend the CFK design.
On the underside of the base is either a 5/8 "thread (Version Z) or a socket for the 12 mm-WILD/LEICA spigot (Model W).
If you want to measure the positions and diameters of branching tubes with the measuring bracket VB1, you should have choose a base in the W version. Please refer to the schematic diagram.
The base in this case can rotate about the rod axis, and will aligned with the observer or the tachymeter.
All other extensions are adapted on a 5/8 "screw.
