GeoMax Zenith 35 Pro

Zenith35 Pro Series
The Zenith35 Pro is equipped with the latest NovAtel measurement engine, with 555 channels multi constellation and frequency support providing unmatched functionality. The unique Zenith35 Pro Tilt&Go functionality allows you to access the inaccessible, ensured by a precise electronic bubble. Its Wi-Fi connection offers the possibility to configure the
Zenith35 Pro from every device. With IP68, the Zenith35 Pro Series is a compact and rugged tool that is water and dust proof.

A corner of a building or even a gully under a parked car? The unique Zenith35 Pro Tilt&Go functionality allows you to measure points where a vertical placement of the pole is not possible such as house corners.
No longer worry about keeping your pole strictly vertical, just Tilt & Go! Seamlessly integrated into the field software, the Zenith35 Pro TAG offers two modes perfectly adapting to the measurement situation.
• TAG Single – when the highest efficiency is needed. Measure points with pole tilted up to 15° with only one press of a button.
Perfectly suited for all your standard tasks, such as topographical surveys and stakeouts.
• TAG Dual – when working under difficult situations. Independent from discrepancies caused by metal objects (or those generating magnetic fields). With pole tilt up to 30°.
When you do have to be sure your pole is vertical, the Zenith35 Pro TAG alerts you when you are outside of the defined centering accuracy, documenting the quality of your measurement.
