3.5.4 Peak with Arrows Response Mode
This uses the two horizontal antennas and provides a “Peak” or maximum
signal response over the center of the radiated signal from the buried line.
The compass line direction indicator shows the direction of the cable
(available in Active modes). The color of the compass changed from clear
to blue when the receiver is in line with the buried line.
This is the most accurate of the locating modes as both antennas are
used to provide a clearly identifiable “Peak”. In the “Peak” mode, a “Peak”
signal indicator helps to clarify the position of the “Peak”. This shows the
last “Peak” located for a few seconds, enabling the user to return to that
position quickly.
Left/Right arrows also guide the user to the line. However, it should be
noted that the arrows use the Null antenna to resolve which arrows are
activated. The null antenna is not as accurate in distorted fields as the
peak antennas. Therefore, when pinpointing, use the peak bargraph to
determine the position of the line.
Note
If the arrows indicated a different position for the cable than the peak
bargraph position, this indicates the possibility of a distorted field. Check
by taking a depth reading on the ground and then lift the cable locator a
known distance such as 0.5m (3ft). If the depth does not increase by this
amount it confirms a distorted field and the data should be treated with
caution.
