trace interval. You can also increase the step size, reduce the time window
and reduce number of stacks.
Figure 6-20: Red letters indicate that speed-interval combination is too fast.
Pressing the + and – buttons under Trace Interval and Travel Speed allows you to set
whichever parameter you want to control; the other is calculated automatically.
Remember that in Free Run mode, data is collected even when the system is not
moving, so proper data collection relies on the operator moving the system at a
consistent speed. Positioning this way is reasonably accurate, but not very precise
because the system movement speed usually varies. It is a best practice to have a
secondary means of positioning the data, for example, a GPS or adding
known positions along the survey line. This way, the data can be rubberbanded in post-
processing software. Note a grid cannot be collected in Free Run mode.
