USING ALTERNATIVE TRANSDUCERS
Wide side operation
The Wide Side Transducer is a specialized "side-looking" transducer that is extremely useful for
bank fishing or looking for bait fish in open water. The Wide Side transducer uses three different
sonar elements that transmit signals to the left, right and straight down from your boat. The
downward beam is 200 kHz with a 24 degree area of coverage. This beam maintains a
continuous digital depth readout from the bottom directly beneath your boat. The side beams are
455 kHz with a 16 degree area of coverage. The side-looking elements can be used
independently, or together to locate targets near the surface of the water on either side of your
boat.
The Wide Side transducer can be connectedly
directly to the 400TX or used in conjunction with the
standard transducer through a transducer switch.
When used with a switch in conjunction with the Tri-
Beam transducer, the 400TX recognizes which
transducer is connected whenever the switch
position is changed.
When a Wide Side transducer is connected, the
screen display changes to display the information
from the side-looking elements. The Wide-Side
transducer has four views available: Left, Right,
Down and Both. These views are controlled by the
View button. The default view is both, in which information from both the left and right elements
are displayed on screen. The digital depth of the water beneath your boat is always present.
Viewing both left and right sides simultaneously
gives you an excellent tool when searching for bait
fish in open water, or when following a creek bed.
However, you will have a greater display resolution
if you view only one side.
The down view is similar to the traditional view
when using the standard transducer, however there
is no Tri-Beam information available, such as fish
location.
When operating in Wide Side mode, the range
must be adjusted manually, since the bottom is often not visible on-screen. Ranges of 15 (5m),
30' (10m) , 60' (20m) and 120' (40m) are available. Also, Zoom is not possible in Wide Side
mode, and the Zoom menu is not available.
