ID
ID is the automatic identification of target returns based on the strength of the returned
signal and other factors. Three options are available: ID "On" displays targets as one of three
different size fish symbols.
Assuming the dual beam transducer is selected, these fish symbols can be either hollow,
indicating that the target is detected in the wide beam only, or solid, indicating that the target is
detected in the narrow beam, and is located directly under the boat.
"ID+", the default setting, provides more information about the location of the target by
attaching depth "strings" showing the digital depth of the target. When there are numerous targets
on-screen, not every target depth is shown, to avoid excessive clutter on-screen.
