Portable Cesium  Magnetometer/Gradiometer

 A Professional  Magnetic Mapping System

The G-858 MagMapper  uses a
graphical interface to make survey
design and data acquisition quick and
efficient.  Various modes of operation
allow the user to custom design a survey
grid for their  particular needs. The
his/her position on the grid  and the
current data profile during the survey.
Sensitivity, resolution, and recording
rate of the cesium magnetometer are
user selectable.

G-858 in action¨ !

G-858 data acquisition offers  either continuous or discrete station recording. The high sampling rate of the instrument  in continuous mode allows the operator to survey an area at a fast walking pace. A wider  search radius can be achieved by using a gradiometer configuration. As a result over-all  costs are inherently lower while data quality remains high.
 

The G-858 is designed to interface easily with standard computers and peripherals.  Geometrics encourages clients to provide their own processing computer hardware. Upon the  client's request
Geotrade will provide a complete and fully integrated processing  station at a nominal price

The G-858 MagMapper system comprises a belt-mounted display/logging console connected to a cesium sensor mounted on a handheld counterbalanced staff. The console contains  electronics to acquire magnetic field data with position and display it on an LCD screen  for review and edit. The console stores high volumes of data in memory. Following the  survey the data is transmitted at
high speed to a processing computer for detailed  analysis.
