67 MID GAIN ADJ (CONSULT BINDICATOR BEFORE MODIFYING!)
Mid Gain Adj allows the adjustment of the TVG curve in the middle distance ranges. It is generally not used. Mid
Gain Adj has two submenus:
•
Position is the distance (in the selected length units) from the face of the transducer to the beginning of
the midrange delay. The default for Position is 0.
•
Delay sets the midrange delay. The distance (in the selected length units) over which the TVG remains
constant. The TVG curve is shifted out past Delay. The default for Delay is 0.
68 ECHO THRESHLD (ECHO THRESHOLD)
Echo Threshld sets the echo threshold from 0 to 100.0%. The default is 35%. The echo threshold is the minimum
amplitude the echo must achieve to be accepted as a valid echo. If the echo has an amplitude less than Echo,
the SonoTracker Series responds as follows:
•
If in Auto TVG mode, the SonoTracker Series increases the amplification until it detects a valid echo or the
amplification reaches High Limit. If the amplification reaches High Limit without detecting a valid echo, the
SonoTracker Series assumes that the echo is not from a valid target, ignores the echo, and transmits the next signal.
•
If in Fixed TVG mode, the SonoTracker Series assumes that the echo is not from a valid target, ignores the
echo, and transmits the next signal.
Note: 100% Echo = 5 VDC, 20% Echo = 1 VDC.
69 PEAK THRESHLD
Peak Threshld sets the peak threshold for return echoes. Peak Threshld only effects the results if the
SonoTracker Series is in Auto TVG mode. If the echo has an amplitude greater than Peak Threshld while in Auto
TVG mode, the SonoTracker Series decreases the amplification until the echo is below Peak Threshld or the
amplification reaches Low Limit. Peak threshold can be set from 0 to 100.0%. The default setting is 50.0%.

71 MINIMUM RANGE
Figure 25: Range/Filters Menu Tree
Minimum Range displays and sets up the minimum range of the transducer. The minimum range is the minimum
distance from the face of the transducer where the SonoTracker Series starts recognizing the return signal
(echo). The default minimum range is set past the transducer’s blind space to avoid interpreting the noise from
the transmission signal as a return signal. However, if there are obstructions near the face of the transducer, the
