Max Depth (Advanced); Water Type (Advanced); Transducer Select - Humminbird 858c Installation And Operation Manual

Max Depth
(Advanced)
Settings: AUTO, 10 to 1500 feet; 3 to 500 meters
[International models only], Default = AUTO
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.
Max Depth controls the down beam reading. The SI Range (Side Imaging®
Range) controls the side beams and down beam reading at the same time.
If SI Range is set to a deeper range than the Max Depth setting, your
898c SI Combo or 998c SI Combo will default to the SI Range setting. For
example, if you set the Max Depth to 50 feet and then set the SI Range to
150 feet, your unit will acquire bottom readings from 150 feet (see Side
Imaging® X-Press™ Menu: SI Range).

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.
Transducer Select allows you to select which transducer you want to use.
The transducer setting must correspond to the transducer type connected to
your system.
