I've had an X-15 for a few years, and have noticed when I'm fishing in soft bottom areas (i.e. mud) I can't get a decent reading from the unit...Lately it will just blink all day, and never lock bottom...when I move into hard bottom areas (i.e. rocks/reefs) it reads perfect....I've tried playing with sensitivity, and all that stuff but can't seem to get it worked out...Any suggesstions?
I'm thinking possibly a transducer problem, but can't understand why it would read as good as it does in only ceartin areas.
Thanks in advance!
