Guys,
Today my Lowrance 3500 depth gauge started the dreaded .5 flash which I assume means the transducer has finally bit the dust. I know nothing about depth finders but was hoping you guys might know a source for a replacement transducer. I also have read just enough to be dangerous and was wonder how one finds the frequency that their depth finder runs. This is in my 2000 Larson and if the transducer isn't available can someone recommend a new unit that would drop-in in place of mine. Thanks for any info in advance.

Look at the old transducer and read the airmark number and hope/pray it is still made, or buy new gauge/transducer combo
