Proximity Number and Threshold
The Proximity Number is designed to increase as the
SR‑24 gets closer to the target line� In many cases, max‑
imizing the Proximity Number is a more accurate way
of pinpointing the location of the target line than Signal
Strength alone�
Use the Proximity Threshold Control to tell the receiver
to ignore targets with depth measurements outside of a
defined range� By setting a threshold for the maximum
depth you can reduce the amount of spurious display ar‑
tifacts that may distract from the locating process�
If the measured depth of the target line is less than the
proximity threshold, the Proximity Number appears as
zero and the Mapping Display is suppressed� If the mea‑
sured depth is greater than the proximity threshold, the
Proximity Number is displayed and the Mapping Display
is shown�

No threshold, no suppression, and

For detections where measured depth
is no greater than 30 m [98 ft]�
For detections where measured depth
is no greater than 10 m [33 ft]�
For detections where measured depth
is no greater than 3 m [10 ft]�
For detections where the measured
depth is greater than 1 m [3 ft]�

allows negative depth to display, and
audio signals reflect Signal Strength�
Note: The Greater Than icon
receiver detects utility lines that are deeper than the
depth shown.
