Basic Signal Patterns
Figure 4. Signals from Vertical and Horizontal Targets
After you have detected the presence of a target, hold the locator vertically and move it back and forth in an “X” pattern. The peak
signal occurs directly over a vertical target, and over the ends of a horizontal target.
The “X” pattern is ideal for pinpointing small objects. A 1-1/4-inch PK nail buried up to 12 inches can be located so precisely with
this technique that it can be uncovered using a 1/2-inch star drill.
Figure 5. “X” Pattern Provides Precision Locating
If you find more than one signal in the vicinity of a target, just raise the locator several inches higher or reduce the sensitivity set-
ting. Any signal that disappears when the locator is raised or the sensitivity is reduced is probably not coming from the actual target.
The signal from a rusty bolt or other small item will decrease much faster with distance than the signal from a larger target such as a
corner marker. An 18-inch length of 3/4-inch pipe can be located at depths up to 9 feet.
