Product Description

A corner of a building or even a gully under a parked car? Measure points where satellite signals are blocked by eaves or canopies? No problem with Zenith35 Pro TAG – just Tilt&Go! Free yourself from working with your pole kept strictly vertical and tilt it up to 30°, and still maintaining GNSS accuracy. Need to ensure you keep your pole vertical? The Zenith35 Pro TAG warns you when outside your defined centering accuracy and documents the quality of your measurements. Ask us about this option!

Remove complexity with access from any device connected to the internet, independent of your location. Connect up to 10 rovers simultaneously via GSM with Zenith35 DynDNS technology. Choose between Zenith35 Pro TAG incorporating the unique Tilt&Go functionality and the standard Zenith35 Pro.

1 year manufacturer’s warranty, and free shipping to the lower 48.

Precision Geosystems offers the GeoMax product line because we believe there is no other hardware manufacturer currently offering the kind of price-to-performance ratio they do. Around here we are all about precision, reliability, and value, and GeoMax fits the bill perfectly. GeoMax is the rough-and-ready younger brother of Leica Geosystems with a pedigree tracing back to the Wild Instrument Company of Heerbrugg, Switzerland. Both Leica and GeoMax are an integral part of Hexagon AB, a world leader in measurement solutions. While Leica developed it’s distinction through technological innovation, GeoMax is making a name for itself by picking the most tried and true instruments off the product line and offering them at prices people can afford. The bottom line is that with GeoMax you get mid-range prices on high-end gear. What more could you ask for?
