Figure 5-7: A time axis (left) and depth axis (right) can be plotted on the left of the data image by pausing the data collection and
pressing Scale once for a time axis and twice for a depth axis.
The user should be aware that if an accurate depth axis is desired, the proper radar wave propagation
velocity (see Section 3.2.6 Radar Velocity on page 39) must be used to generate the correct depth.
