Using Alternative Transducers - Humminbird Tour Series Operation Manual

The second Diagnostic screen evaluates external connections to the
unit. The first category is Transducer input. If a transducer is detected, a
message will indicate "connected". This is an excellent way to confirm
transducer connection. If a transducer is connected directly to the unit,
the connection will be indicated here. If a switch is used, use Diagnostic
to confirm the connections from each transducer. If a series of dashed
lines is shown, then no transducer is connected or there is a problem
with the transducer or cable.
The next categories indicate the connection of boat speed sensor and
surface water temperature sensor. These accessory sensors can be
purchased independently or together as a single sensor (see Available
Accessories). If the sensors are connected and working properly, a
"connected" message will appear.
Note: This feature only works when the boat is in motion as the paddle wheel on the speed sensor must
rotate to be detected.
The voltage input category is especially helpful in diagnosing input voltage problems. The current input
voltage will be displayed. If voltage fluctuations or power supply in excess of 16 VDC or less than 10 VDC
is suspected, use the diagnostic screen to confirm input voltage. Often, small outboard motors do not
effectively regulate voltage when operated at high engine speeds. Use Diagnostic while running the boat
at high speeds to show the voltage gain. Also, if you are using the Tour Series in portable configuration or
from the trolling motor battery, Diagnostic can be used to evaluate the health of the battery by showing
the current voltage.
The total time category indicates the total time the unit has been in use since shipped from the factory.
Note: It is normal for some hours to be indicated in the total time when the unit is new due to factory
testing.
While this is often of interest to the user, it is primarily a diagnostic tool for the repair technician should
service be required.
Press MENU again to exit Diagnostic.

USING ALTERNATIVE TRANSDUCERS

The Tour Series is designed to operate with the Tri-Beam transducer included standard with the product.
The standard transducer can be mounted on the transom of the boat, or bonded to the inside of most
fiberglass hulls. Tri-beam transducers are also available in trolling motor mounts, portable mounts, and
bronze thru-hull type mounts.
The Tour Series also has the ability to work with the Wide Side Accessory Transducer. See Available
Accessories for selection of the transducer.
