Max Depth
(Advanced)
Max Depth adjusts the maximum depth of operation. The performance of your Matrix®
Fishing System can be tuned to the maximum depth you will be fishing in by setting the Max
Depth. When a maximum depth is set, your unit will not attempt to acquire sonar data
below that depth, thus increasing overall performance. When Max Depth is set to Auto, your
unit will acquire bottom readings as needed (within the depth capacity of the unit). If the
bottom is deeper than the Max Depth setting, the digital depth readout will flash, indicating
that your unit 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 1000 feet, 3 to 330 meters [International Models Only], Default =
AUTO)
Water Type
(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)
