Adaptable Scanning Modes
NX25 was designed with job conditions in mind. An adjustable survey wheel is used to seamlessly switch between cross-polarized, standard, and side-car scanning modes as required.
Choose the Interface
NX25 with the Nexus Elements Interface makes it easy to perform mark-and-go scanning. For more complex activities, when data needs to be saved or when advanced analysis is required, the entire system should be connected to Flex NX or Flex LT.
Optional Accessories
To scan difficult-to-reach areas like ceilings and high walls, the NX telescoping pole accessory can be attached to the system.

Jobsite Ready Design
The system is built with a hard, lightweight magnesium housing and engineering-grade plastics, providing enhanced durability and dependable performance for everyday activities.
All Day Battery Life
The antenna being used should work the same hours the job requires. NX25 has two lithium-ion batteries, providing a total battery life of more than 10 hours.
Built to Last
Every NX25 antenna comes with a two-year warranty.
GSS Has Got Users’ Back
GSS’s mission is to make the users successful, and hence NX25 comes standard with two years of complimentary in-house training and support.
