Robotic Total Station

Dramatically minimise the time of any survey task and boost your performance and accuracy to the maximum.

Zoom90 is the ultimate one-man system with up to 20% more automation performance, extended refl ectorless measurement capability, STReAM360, accXess technologies and Windows CE open connectivity. Because a perfect solution is more than its single components, the Zoom90 seamless integration makes it the ultimate solution.


Scout: Scans the entire working area within seconds to quickly fi nd the target.

TRack: Continuously track targets. Once locked onto, the instrument remains accurately aimed on the moving target.

AiM: Aims accurately at any prism, without needing to look through the telescope. Measurements are performed automatically with consistently  high and repeatable dependability.


Zoom90 incorporates highly innovative X-motion hybrid drives, promoting automation performance compared to conventional drives. It will follow your target at 90 km/h at 100 m distance


GeoMax’s accXess EDM Technology provides leading refl ectorless measurements up to 1000 m. The extra small laser footprint and the sophisticated signal-processing technology, ensure you accuracy - regardless of the distance or conditions.

Fitted as standard in the telescope, the NavLight is an efficient alignment aid, helping to speed up work while setting out. Its flashing red and yellow lights will guide you quickly and exactly to the line of sight.

Zoom90 meets all your connectivity needs. Use its built-in Bluetooth® for medium range data transfer or its Bluetooth® handle for high performance long range Bluetooth®. Either way, it is ideal for one-man robotic surveys. Store data on Zoom90’s extra large internal memory, on the removable SD card or the USB stick using plug and play technology. 

GeoMax instruments are built to withstand the toughest conditions. The Zoom90 has been designed and tested to be dust-proof and fully protected against water jets.
Combine your preferred software and datalogger to perform remote control tasks with increased productivity. Zoom90 uses the Windows CE operating system, which enables a variety of powerful field software to be run, offering you freedom to choose software that best suits your needs. Full VGA colour-touch display will also provide you with superior performance and full graphic capability.
