Discrimination Audio

Unlike the all-metal channel, the discrimination channel

does not treat all targets alike. Discrimination uses the VDI

(phase) response of the target to determine how to respond. It is

possible to assign different tones to different VDI responses, or

to completely ignore targets with certain VDI responses.

Discrimination Sensitivity

In this channel, the Discrimination Sensitivity setting deter-

mines a threshold level above which you will hear target

responses. In many detectors, this setting is simply called

Threshold, but VX

has separate adjustments for each channel.

The following graph shows the relationship between the thresh-

old level and the detection signal. Only detection signals that

exceed the threshold level (shaded in gray) will become audible

target signals. Otherwise, you will only hear the threshold tone.

Increasing the Discrimination Sensitivity setting lowers the

threshold, making VX

more sensitive to weak target signals.

Like All-Metal Sensitivity, this can also increase the amount of

audio noise, and can make VX

more chattery, especially when

EMI is present.

Threshold Volume

The loudness of the discrimination threshold tone is set by

the

AudioAudio Threshold control. Setting the threshold vol-

ume all the way to zero will result in silent-search (no threshold

tone).
