Volume gain affects the way the detector amplifies target audio responses in respect to the strength of the original signal.
Looking at figure 5.16, it is clear that with a setting of 1 the sound produced will be proportional to the strength of the signal for the whole range of signals. Based on this and the depth indication, some information on the size of the target can be inferred. It should be noted that in this case weak signals will produce an accordingly faint audio signal.
With the preset value of 5, the audio response is being partially amplified. Weak to medium strength signals will give proportional responses, but strong signals will not sound much louder than medium ones because the sound has reached its maximum limit (Figure 5.17).
On the other hand, with a setting of 10, all but the weakest signals will be amplified to a very strong audio response (Figure 5.16). No indication of size or strength of target signal can be deduced in this case, but even weak target signals will be easier to hear.
