My sounder is a Furuno
LS4100, it has both 50 and 200 htz frequencies. The display unit is only 2 years old, but the transducer is 13years.
Normally, this unit does an outstanding job of displaying depth
During the last few days I have been getting erratic signals. Not only will I get a blank screen
, but often the readings are WAY off. 1000 ft in 15 ft for example.
It seems to be able to hit once in a while on the 200htz setting, while the 50htz setting hardly even shows any signal, but is always wrong.
The transducer is a thru hull
. mounted about 1/3 from the bow just to the port of the keel
- pretty much the perfect location. No growth, just hauled for bottom paint
this past June, so that is not it.
Also, it pretty much suddenly started acting up.
Would anyone know if this is sounds like a transducer going bad?
