Max Depth
(Advanced)
Max Depth adjusts the maximum depth of operation. The performance of your Matrix™ can be tuned
to the maximum depth you will be fishing in by setting the Max Depth. When a maximum depth is
set, your Matrix™ will not attempt to acquire sonar data below that depth, thus increasing overall
performance. When Max Depth is set to Auto, the Matrix™ 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 Matrix™ cannot locate the bottom. The Max Depth menu choice
is available when User Mode is set to Advanced (see Setup Menu Tab: User Mode).
T
o 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)
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)
Transducer Select
Transducer Select allows you to select which transducer you want
to use (the Matrix™ comes with a DualBeamPLUS™ transducer, and also supports the optional-
purchase QuadraBeam™ and WideSide® transducers.)
T
o change the selected Transducer:
1. Highlight Transducer Select on the Sonar Main menu.
2. Use the LEFT or RIGHT 4-WAY Cursor Control keys to change the transducer selected.
