Boat Speed/Water Temperature Connection. Other connections tested
include the boat speed and surface water temperature sensors. These accessory
sensors can be purchased independently or together as a single sensor (see the
Humminbird Accessories catalog). If the sensors are connected and working
properly, a “connected” message appears.
The speed input feature only works when the boat is in motion as the paddle
wheel on the speed sensor must rotate to be detected.
Voltage Input. Another connection tested is the voltage input, and is
especially helpful in diagnosing input voltage problems. The current input
voltage is displayed. If voltage fluctuations or power supply in excess of 20 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 350TX 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.
Total Time. The total time category indicates the
total time the unit has been in use since shipped
from the factory. It is normal for some hours to
appear 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 the unit
need service.
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
