Rising Tone
Falling Tone
The Response function allows you to invert
the normal pitch combination of target signals
to different size targets.
Normally, a large/deep target has a falling-
then-rising tonal response and a small/
shallow target has a rising-then-falling tonal
response. Most targets tend to be small, so
you can become accustomed to hearing that
small/shallow target tonal response. If you are
detecting for deep targets, the response can
be inverted so that a deep target signal has
the same response as a small/shallow target.
Small Target Deep Target
Normal
When Normal is selected and a small target is
detected the pitch normally rises to a higher
pitch and then falls to a lower pitch. When
a deep/large target is detected the tone
normally falls and then rises in pitch.
Inverted
When Inverted is selected and a small target is
detected the tone will first fall to a lower pitch
and then rise, and a deep/large target will first
rise in pitch and then fall.
Response is a personal preference and is quite
dependant on your hearing.
