The G-858 MagMapper is a high sensitivity, fast-sampling ‘walking’ magnetometer. Its console includes a graphical interface that makes survey design and data review simple and efficient. The G-858 provides various modes of operation to allow users to custom design a survey grid for their particular needs. Instrument operators have the ability to view their position on the grid and the current data profile during the survey. Display resolution, audible alerts, sample rate and many other functions are user selectable.
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 zone can be achieved by adding a second sensor. Adding a second sensor also provides the ability to measure the magnetic field gradient.
The G-858 is designed to interface easily with standard computers and peripherals. Geometrics encourages clients to provide their own processing computer hardware.
