progressive filtering of the sonar returns. High 1, High 2, and High 3 are useful when there is
excessive trolling motor noise, but in some deep water situations, the High settings may actually

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.

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.

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 1198c 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).
