AUDIO RES.
4
Audio Response enables you to amplify the volume of deep targets . It gives the impres-
sion of greater power, but does not provide any additional depth as this setting only af-
fects the sound curve (the dynamic range of sounds). Lower Audio response levels give
a good perception of depth.
0 = Weak Audio Response
7 = Maximum Audio Response
Audio Response
In terms of pure performance, the greatest detection ranges are obtained with low reactivity levels. How-
ever, you will find more targets and will detect deeper on mineralized ground with medium or high reactivity
levels. So do not just rely on performance in the air!
Depending on the reactivity level, the length of the audio signal varies when it passes over a target, the
length of crackling of ferrous items is also in proportion. You are therefore advised not to keep changing
the performance settings, as this may hinder you from distinguishing good and bad sounds.
Low reactivity (0 to 2) = long sound High reactivity (2.5 to 5) = Short sound
Reactivity ...
Be aware that by increasing the Audio Response too much:
• You also amplify the small false signals and mask sounds from a good target.
• You compress the dynamics and reduce the assessment of the distance of a target.

0 to 1
Large masses and coins, in ground not contaminated by ferrous items.
2 to 2.5
General use, ground with little iron contamination.
3 to 5
iron-contaminated and/or mineralized ground.
E.g. Passing the coil over an iron object close to
the surface then over a good metal target (ring).
A high Reactivity level enables you to distinguish the
ring completely from the iron. The audio signal fully
indicates the target.
With a medium Reactivity level, you begin to detect the
ring. The audio signal partially indicates the target.
With a low Reactivity level, the iron is detected for
longer and completely hides the ring.
