Leica Zeno 20
More than GPS
Outdoor experience
More software
Zeno 20 is tough and built to last.
Lightweight and compact, it fits in one
hand, with the largest, best-in-class
screen and a dust and water
resistance IP67 rating. An out-of-box
experience, Zeno 20 is ready to work
when you are. Just unpack and go.
Overcome GNSS limitations and
extend productivity. gamtec merges
two great tools, the Zeno 20 and the
DISTO™ S910, to create a contactless
offset measuring solution, increasing
safety dramatically in the field while
maintaining highest accuracy.
By choosing either Android or
Windows Embedded Handheld
operating systems, users can add their
favourite mobile Apps, such as the
Zeno Mobile, Zeno Field or any third
party software to simplify workflows
and maximise flexibility.
