Target ID and Sound Modes
Numerical Target ID Display: Represents the Target conductivity and is always displayed. Non-ferrous
Targets have positive numbers and ferrous Targets have negative numbers. The target ID number range
is from -30 to +30 and is a function of the target’s shape, thickness and the metal conductivity. The
lower the ID number, the lower the target conductivity; the higher the ID number, the higher the target
conductivity.
Sound Modes: There are 3 sound profiles (All Metal, Discrimination, and Mix Mode) with 4 tones total.
The graph provided in section
Discrimination Breakdown Visuals
gives a visual representation
when one of the 4 tones is heard, based on one of the 3 sound profiles being used. The 4 tones are as
indicated:
1. Low Tone: Represents ferrous Targets.
(Only heard in Discrimination and Mix Mode)
2. Low-High Tone: Represents All Metal Mode.
(Only heard in All Metal Mode and Mix Mode)
3. High-low Tone: Represents low conductivity non-ferrous Targets.
(Only heard in Discrimination and Mix Mode)
4. High Tone: Represents high conductivity non-ferrous Targets.
(Only heard in Discrimination and Mix Mode)
1. All M (All metal): Only the Low-High tone will be heard when a Target is located.
(Numerical Target ID is always present in All Metal Mode)
2. Disc (Discrimination): This mode allows 3 different tones associated with the target ID and for the
sound to be silent based on the target ID and discrimination settings:
2a. If the Discrimination set point lies within the range of -30 to 0, any Target with a Target ID
lower than the set point will be silenced.
(Numerical Target ID is always present)
2b. If the Discrimination set point lies within the range of 0 to +30, any Target with a Target ID
lower than 0 shall be silenced and any Target within the range of +/-2 of the Discrimination set
point shall also be silenced.
(Numerical Target ID is always present)
3. Mix (Mix Mode): This mode combines both All Metal Mode and Discrimination Mode reporting in
sequence. The first tone is the All Metal sound. The second tone is the Discrimination sound. (The disc
sound may be silenced based on the discrimination settings and target ID)
Pin Point Sound: The sound’s magnitude and frequency are modulated depending on the target signal
strength. The stronger the signal, the higher the audio frequency and louder the audio report will be (ID
VCO style).
