C. Induction Peak (Ind Pk)
TRACE [3] + Mode [SK] + Ind Pk [SK Toggle]
or Menu/OK [6] + Cable/Pipe [SK] + Mode [SK] + Ind Pk [SK Toggle]
If you cannot make a direct connection, or use the 3M™ Dyna-Coupler clamp to apply a
locating signal on the target, use the induction method. This method uses the internal coil
of the transmitter to generate a magnetic field.
The Induction Peak mode of the receiver is a mode in which the upper antenna of the
receiver is tuned to minimize distortion from the magnetic field of the transmitter.

D. Directional Peak (Dir Pk)
TRACE [3] + Mode [SK] + Dir Pk [SK Toggle]
or Menu/OK [6] + Cable/Pipe [SK] + Mode [SK] + Dir Pk [SK Toggle]
In Dir Pk mode, four peak antennas are used to analyze the magnetic field pattern. The
bar graph indicates signal strength and the directional arrows sense the edges of the
magnetic field. The left/right arrows will indicate the direction to the nearest cable/pipe
that is in-line with the receiver handle.
As the antenna crosses the cable or pipe, the receiver speaker volume increases to a
maximum, the
Bar Graph
[11] fills from both sides toward the middle, and the numeric
Signal Strength
[15] increases. As the antenna moves off the target path, the speaker volume
decreases and the
Bar Graph
opens. Use the bar graph and the numeric
Signal Strength
to
locate the exact target path.

Right of Target Path
Once the target path has been located, the arrows at the top of the display will indicate
the location of the target path in relationship to the receiver handle.
Note: When field distortion (due to congestion) is affecting the receiver, the left/right
arrows may not coincide with the bar graph. Use the maximum numerical Signal
Strength to target the cable or pipe.
