Stop-and-Go
For larger and deeper targets; at depths below 30 metres (100 feet), such as
those more often encountered in mineral exploration applications, it is
preferable to operate in the stop-and-go mode with automatic station
incrementing. Data for this case would be taken typically at a 15 metre (50
feet) station spacing—remember, you need at least two points to define an
anomaly, which is why the station spacing is half that of the expected depth.
This is illustrated in the following figure (Figure B16), which shows the set-up
of a stop-and-go survey.
