New Field Ready Tablet

Leica CS30

When you are getting ready for an all-day job, you want to be sure you are equipped with tools to keep you efficient and the controller is the critical link between surveyor, sensors and office.  Leica CS30 tablet is a versatile controller designed for durability.


New Imaging GNSS

The GS18 I matches the same intelligent tilt technology of the GS18 T and the advanced signal tracking capabilities of the smartest GNSS antennas—but the GS18 I takes another step forward in technological innovation. With the new addition of an imaging sensor, the GS18 I lets you perform photogrammetric measurements on the fly.


The New MultiStation

The Leica Nova MS60 combines an artificially intelligent total station, digital imaging, GNSS connectivity and 3D laser scanning in a single instrument, all delivered in the size and weight of a total station that can easily be operated by one person.
