unit 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.
Applications:
The G-865AX 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 MagMap2000
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 G-856AX as a base station
unit for the measurement of diurnal changes
in the earth’s magnetic field. Diurnal
correction data is then downloaded by
MagMap2000 and can be applied to other
856, 858 or 822/823 airborne data.
The G-856 provides a reliable, low cost
solution for a variety of magnetic search and
mapping applications. Single key stroke
operation means the G-856AX can be operated
by non-technical field personnel or used in
teaching environments. The G-856AX 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. The
