Max Depth (Advanced); Water Type (Advanced) - Humminbird 900 Series Installation And Operation Manual

Max Depth adjusts the maximum depth of operation. The performance of
your 900 Series™ can be tuned to the maximum depth you will be fishing in
by setting the Max Depth. When a maximum depth is set, your 900 Series™
will not attempt to acquire sonar data below that depth, thus increasing
overall performance. When Max Depth is set to Auto, the 900 Series™ will
acquire bottom readings as needed (within the capacity of the unit). If the
bottom is deeper than the Max Depth setting, the digital depth readout will
flash, indicating that the 900 Series™ cannot locate the bottom. The Max
Depth menu choice is available when User Mode is set to Advanced (see
Setup Menu Tab: User Mode).
To change the Max Depth setting:
1. Make sure you are in Advanced User Mode, then highlight Max
Depth on the Sonar main menu.
2. Use the LEFT or RIGHT 4-WAY Cursor Control keys to change the
Max Depth setting. (AUTO, 10 to 1500 feet; 3 to 500 meters
[International models only], Default = AUTO)

(Advanced)
Water Type configures your unit for operation in fresh or salt water. The
Water Type menu choice is available when User Mode is set to Advanced
(see Setup Menu Tab: User Mode).
NOTE: 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. Also, make sure that the Water Type is set
accurately, especially in salt water, as this affects the accuracy of deep water
depth readings.
To change the Water Type setting:
1. Make sure you are in Advanced User Mode, then highlight Water
Type on the Sonar main menu.
2. Use the LEFT or RIGHT 4-WAY Cursor Control keys to change the
Water Type setting. (Fresh, Salt, Default = Fresh)
