Max Depth (Advanced); Water Type (Advanced); Imaging Palette (Down Imaging™ Views Only [570 Di]) - Humminbird 561 Operation Manual

Max Depth controls the maximum depth of operation. When Max Depth is set
to Auto, the Fishfinder will acquire bottom readings as needed (within the
capacity of the unit). When Max Depth is set to match your fishing maximum
depth, your Fishfinder will not attempt to acquire sonar data below that depth,
so more detail will be shown on the screen.
NOTE: If the bottom is deeper than the Max Depth setting, the digital depth readout
will flash, indicating that the Fishfinder cannot locate the bottom.
Water Type configures your unit for operation in fresh or salt water. In salt
water, you can also choose the shallow or deep setting.
Water Type affects the accuracy of deep water depth readings. In salt water,
what would be considered a large fish might be 2 to 10 times bigger than a
large fish in fresh water (depending on the type of fish you are seeking). The
salt water setting allows for a greater range in fish size adjustment to account
for this difference.
Imaging Palette allows you to select which monochrome palette you would like
to use for the Down Imaging™ display.
