Title: Transducer is making a electric noise when unit is on
Post by: Beaulieu80 on July 15, 2014, 08:44:31 AM: Hi guys,

my unit transducer (XNT 9 SI 180 T) is doing a funny noise when I turn on my 798 unit. Is this a normal behavior? Would that be the reason why I do not see any fish on my sonar for the last 2 months?

Is this a tick, tick, tick sound?
Is the transducer in the water when it does this or is this when out of the water?
What type of boat do you have (metal, fiberglass, wood) and where is the transducer mounted?

I have a aluminium walleye V boat and it is mounted to a mobile bracket so I can use my unit with my other boats.

the bracket is about 8inch of my motor (40hp)
