Show echograms - In mode 1x to 5x the centre echograms can
be chosen by selecting the transducer number in the waterfall
view. Example: If 3x is chosen and echogram 5 is centre, the
echograms 4 and 6 will be displayed in each side of echogram 5.
Bottom:
• On - The detected bottom depth is shown as a thin line in the
echogram. The line is drawn in the current foreground
colour; black during day and white during night.
• Off - The bottom line is switched off.
• White Line - A band in the current background colour is
drawn below the detected bottom depth.
Variable Depth - When enabled a horizontal depth line is
placed wherever you click in the Echogram view. The depth of
the line is displayed at the left end of it. In the History diagram
the depth for each ping is displayed individually.
Trawl - Headrope and footrope depth are indicated by two red
lines in the echogram. Continuous lines are drawn when the
current depth values are available, and dotted lines are drawn
for a period of two minutes when this information is not
available. No lines are drawn after two minutes.
Range other - Two horizontal lines indicate the range presented
in the lower echo frame.
Purse Seine - The depth of the purse seine sensor is indicated.
Vertical Markers
Event - A vertical line is drawn when a new event is generated.
Minute - A short vertical line is drawn in the upper part of the
echogram once every minute.
New Range - A vertical line is drawn when the range is
changed. The old range is written on the screen as an
annotation.
Gain
No - No TVG is applied. The echogram displays the input
power level at the transducer terminals. This echogram type is
used for special purposes when TVG is not applicable or
required..
School - The echogram displays volume backscattering strength
above the detected bottom, and surface backscattering strength
below the detected bottom. Volume backscattering strength is
suitable when observing a school of fish, and surface
backscattering strength is suitable when studying the properties
of the bottom.
