Surveying in the Stop-and-Go mode
You can also acquire data in the stop-and-go mode with automatic station incre-
ments. This mode is most commonly used in mineral exploration surveys, where
the targets are usually larger and deeper than in environmental applications. The
following figure (Figure B-25) illustrates a staff-mounted sensor used in the stop-
and-go mode.
Figure B-25 Staff-mounted sensor set-up.
Again certain points should be mentioned about this type of survey:
▲ it is important that the sensor cable does not dangle for the same
reasons as mentioned for the WALKMAG mode,
▲ the sensor staff should be held at arm’s length when taking a
measurement,
▲ it is very important that the sensor be maintained in a constant and
proper orientation for each line.
