G-864 Magnetometer | Geometrics

The G-864 marries the highest quality magnetometer available today with a modern user interface, making surveying easier and more efficient for years to come. The G-864 cesium magnetometer utilizes a modified Android tablet, the Getac ZX70, as the data console. This offers users the ability to store large amounts of data as either a single or multiple projects.

Features and Benefits:
Android Acquisition Software: Modern user interface allows for WiFi communication and unlimited expansion of features.
GPS Navigation: No more staking! Define survey geometry beforehand to limit field time.
In-Field Data Review – Plot GPS positions, analyze profiles, and create a color contour map before leaving the field.
Supports 4 Sensors: Cover more area, faster by logging from 4 magnetometers at once and defining the sensor separation.
Data Saved to Tablet and Backpack: Avoid data loss with data redundancy.
