Sonar Menu Tab
Max Depth
(Advanced)
Settings: Auto to 800 ft, Auto to 1200 ft (561 only), or Auto
to 260 m (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.
Water Type
(Advanced)
Settings: Fresh, Salt (shallow), Salt (deep); Default = Fresh
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.
