appears around the sensitivity level bars. The  buttons
adjust the level from minimum (1 bar) to maximum (10 bars).
Normally, this determines how deep the detector will “see” a
target. In general, run the sensitivity as high as possible while
maintaining smooth operation. If the audio is chattery or the
ground is causing overload, reduce the sensitivity.
• Volume
This is loudness of the target response. Range is 1-99.
• Threshold
This is the loudness of the threshold audio, which is the
background hum. Range is 0-99. A modest setting (20 is typical
when using headphones) helps with faint target responses which
may be too deep to trigger a Tone ID but are audible as a thresh-
old variation. This is especially true in All-Metal or Mixed-
Mode (Relic mode) audio. A setting of 0 results in silent search
(no threshold), in which a target response may not be heard
unless it is strong enough to trigger a Tone ID.
• Tone ID
The MX5 has three selectable Tone ID responses: 1, 2, and 8
tones. Use the  buttons to move through the tone selections.
See the “In Depth” section for detailed descriptions.
DISC — Discrimination
The Discrimination control allows you to enable or disable
the audio response for select ranges of targets. The MX5 has a
20 segment discrimination control. The  buttons move a
disc cursor ( ) across the segments, and pressing the
DISC
but-
ton will toggle the response for the selected segment. The
example Disc Mask below shows that the first 5 segments
(mostly the iron range) have been disabled, plus the segment
that corresponds to Zinc cents. The remaining segments are
enabled. The disc cursor is resting on the “70” segment.
