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 Fishing System comes with a DualBeam PLUS TM transducer, and also supports the
optional-purchase QuadraBeam TM and WideSide transducers.)
To 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.
(DualBeam, QuadraBeam, WideSide, Default = DualBeam)
