Geomax Zenith 25

GeoMax_Zenith25GNSS system with ultimate reliability and robustness even in extreme environments that “works when you do”.

The Q-Lock™ technology tracks all satellites with the highest available signal strength and performs regular independent checks to ensure that you can work even in challenging environments such as urban canyons or under heavy foliage. This all combined in a system robust enough to withstand a 2 m topple over and a complete submersion under water.
