4.5 Depth and Current Measurements
When the receiver is located directly over the centerline (the left/right position is at the null), the
Depth button ("down" section of 4-way navigation key) can be used to estimate both the depth
and current of the target line. The receiver must be at rest, and held in a vertical position with the
tip on the ground. At this position, the audio output is silent, indicating that the receiver is at the
centerline.
Do not solely rely on centering at the null for accurate depth and current measurements.
The centerline should be marked using the peak blue signal level bar and maximum
signal strength reading.

When the Depth button is pressed, the receiver averages the signal strength for a few seconds
and displays the results.
