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.
"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
ID "OFF" disables the units interpretation of targets, and displays the "raw" sonar information as it is received. Advanced users may prefer this type of presentation, so they can make there own interpretation from the information displayed.
Scroll
Scroll Rate controls the update rate of the display. There are five rate settings available. You may speed up or slow down the rate to match your personal preference. To present the most accurate representation of the terrain beneath your boat, the scroll rate of the display should be approximately synchronized to the speed of the boat. If your boat is stationary, or moving slowly, select a slower scroll rate, and if you typically operate the boat at high speeds, use a faster scroll rate.
