3.1 Surveying
When a survey has been initiated the main menu changes,
see figure below. Now the user may stop the survey, save a
jpeg-image of the current screen check the velocity trough
hyperbola fitting or save a GPS-marker on the current location.
The radargram screen is split in two
– the upper part shows
the high frequency part of the data, the lower the low
frequency part.
An important feature in the instrument is the track-cursor
pointed to by the red-arrow in the figure. This cursor will move
with the system, so that if the unit is moved backwards, this
cursor along with a vertical line will start to move back on the
screen. This is the primary function used when locating buried
targets. When the unit is pushed forward again, data collection
will start when you reach the point where you started to move
backward, not before.
