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 their 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.
