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 Fishing System comes with a DualBeam PLUS™
transducer, and also supports the optional-purchase QuadraBeam PLUS™
transducer.)
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. (Compact Side Scan, QuadBeam, Universal Sonar 2,
Default = Compact Side Scan)
