Simrad ES60
86
Surface - Auto Start - The echogram is related to the sea
surface. Vertical range is manually selected in the Surface
Range dialogue box. The ES60 performs automatic adjustment
of the start depth keeping the bottom echo inside the visible
echogram.
Bottom - The echogram is related to the detected bottom. Stop
depth (lower echogram boundary) and vertical range are
manually selected in the Bottom Range dialogue box. The
echogram is only drawn for pings having a successful bottom
detection.
Trawl - Trawl sensor systems communicate headrope depth and
headrope-to-footrope distance to the ES60 at regular intervals.
The echogram covers the vertical opening of the trawl including
a small margin at each side. The headrope and footrope margins
are identical. Their size is selected in the Trawl Range dialogue
box. The headrope-to-footrope distance can be manually set in
the Trawl Interface dialogue box for trawl sensor systems not
measuring the trawl opening, or when the measured
headrope-to-footrope distance is unreliable. The echogram is
only drawn when trawl position information is available.
Port/starboard - Define if the current sidescan transducer is
mounted on the port or starboard side of the vessel.
Range view - The echogram will display both the water column
and the bottom. Valid for both single and dual systems.
Across view - If a vertical transducer is available, the bottom
echogram will expand (hiding the water column). The extent of
expansion (in metres) is set by the vertical depth. Valid for both
single and dual systems.
Import - It is possible to display both port and starboard
sidescan echograms in the same view. When opening the
echogram dialogue for one transducer channel, select the other
transducer channel to be imported in the drop-down list, then
click the Import box. This function is only valid for dual
systems.
Horizontal Depth Lines
Scale - Equidistant horizontal scale lines are drawn inside the
echogram in the current foreground colour; black during day
and white during night. A maximum of 50 scale lines can be
drawn. No scale lines are drawn when the scale line count is set
to zero.
Each echogram will be labeled with a number placed on the TX
pulse in each channel.
