Operating the ENVI-MAG
The information in this chapter is not intended to be a complete tutorial on
magnetic surveying, rather it highlights the unique features of the ENVI-MAG.
Section 2–Applications of this manual covers this subject in more detail. This
chapter will cover the following:
â–² guidelines for obtaining accurate, meaningful measurements,
â–² tips on field procedures with the ENVI-MAG,
â–² a sample WALKMAG (automatic) mode of survey (basic mode),
â–² a sample Stop-and-Go (semi-automatic) mode of survey (advanced),
â–² base-station operation (advanced),
â–² search-mode surveys,
â–² data correction procedures using the base-station, tie-line or
loop survey modes,
â–² operating the ENVI-MAG under the control of another host computer
(Remote operation).
Accurate and meaningful measurements
The quality of your measurements are greatly affected by the sensor orientation, mag-
netic gradients and any other source of noise near the sensor. Accurate, meaningful
measurements can only be made by observing some simple guidelines as discussed
in the following sections.
