The G856f provides a reliable, low cost solution for a variety of magnetic search and mapping applications. Single key stroke operation means the G856AX can be operated by non-technical field personnel or used in teaching environments.
The G856AX uses the established proton precession method, allowing accurate measurements to be made with virtually no dependence upon variables such as sensor orientation, temperature, or location. Theunit provides a repeatable absolute total field magnetic reading, traceable to the National Bureau of Standards, unlike other magnetic field measurement processes which measure only a single component of the field.

The G-865f is ideal for mapping geological structures, for mineral exploration, magnetic search for industrial, environmental or archaeological targets. The optional gradiometer attachment gives greater resolution and noise immunity for conducting searches in industrial or high cultural noise environments. Simple operation, large digital data storage capability, and the inclusion of MagMap 96 data transfer and editing software provides a system well suited for both teaching and survey applications. The automated cycling option with long sensor cable and external power connection allows use of the G856AX as a Basestation unit for the measurement of diurnal changes in the earth's magnetic field. Diurnal correction data is then downloaded by MagMap96 and can be applied to other 856, 858 or Airborne data.

Superior Data Editing Software.
MagMap 96 allows rapid down load of the data form the G856f to a PC. Data can be diurnally corrected, profile lines and positions diplayed and edited, noisy readings filtered and QC plots of profiles, 2D contour and 3D surface plots made. Data can be exported to Surfer or Geosoft for more sophisticated final maps and analysis. The software requires Windows 95, 98 or NT operating systems. A thoroughly well proven design (over 2,000 units sold) , excellent performance and the lowest price professional system are key features of the G-856f. Combined with the ease of use, user friendly download/editing software, and readily available commercialcontouring programs, the G-856f represents a complete magnetic surveying package generating high quality data for budget conscious users.
