MD Interrogation Mode

Interrogation Mode provides information regarding characteristics and
composition of a target.
When using the detector in Dual Sensor Mode,
the separate MD and GPR signals may be used to
differentiate targets of different types.
For example, a large metallic object will generate
a high target response from both the MD and
GPR, while a large non‑metallic object would
generate a high target response from the GPR but
little to no response from the MD.
Conversely, a very small metallic target may
not generate a response from the GPR, but still
generate a response from the MD.

Interrogation Mode Audio

MD Interrogation Mode will provide an audio
tone related to the targets ferrous content and
conductivity. The detection tone in Interrogation
Mode is not related to the target size and
proximity as it is in MD Detection Mode.

Interrogation Mode Procedure

1. Ensure that the MD Sensor is enabled.
Interrogation Mode cannot be enabled when
operating only the GPR Sensor.
2. Press and release the Trigger button once to
enable Interrogation Mode.
The Target Identification (ID) Field will be
displayed (see page 52 for detailed Target ID
information).
Audio feedback will change; Interrogation
Mode audio will vary in tone corresponding to
the target composition (see page 30).
A Target ID will also be displayed on the LCD
corresponding to the tone emitted.
3. Pass the coil over the target to be interrogated,
while paying attention to target feedback and
reviewing the Target ID.
4. Press and release the Trigger button to return
to Detection Mode.
Note: Interrogation Mode will provide a specific
tone for a target. However, the tone is not unique
and other targets may produce the same type
of tone. In different types of soil, the same target
may give a different tone when interrogated.
