Version 5 and version 6 magnetometers are fully compatible for unit to unit diurnal correction
whether they are used as Base or Mobile. Older units however, may not be fully compatible with
the version 6 magnetometers but you can always perform file-to-file correction using GEMLinkW.
NOTE:
When units older than version 5 are in use, it is advised to use File-to-File
correction.
This is because (in the event of incompatible file formats) the original mobile file
may be damaged when combined with the base file.
