This Bar shows that
around 10 Targets at this
amplitude have been
detected in the last time
period (2 minutes).

No Targets will be shown
on the Histogram if they
are below the Target

Detection Mode selection.
Presets are either Mode
1 or Mode 2, with varying
descrimination settings
3.4.4 Detection Mode
WMB-X230 offers two modes for fish detection (Mode 1 and Mode 2). Both modes detect fish, but
vary slightly in their approach.
Seafloor discrimination settings will adjust how detections occur on outer beams. When discrimination
is set to none, the detection algorithm will try to detect targets as close to the seafloor as possible,
but may incorrectly identify part of the seafloor return as targets. When discrimination is set high, the
detection algorithm will try to ignore targets close to the seafloor in case they are part of the seafloor
return. Medium discrimination is a balance between the two.
