In midsummer 2002 I installed an Eagle Fishmark on my pontoon boot.
Its a great unit. After about two or three uses this year, I have
noticed that the depth readings do not work in less than 7 or 8 feet
of water. The depth reading blinks or goes to zero.

I use a full service marina to paint my boat every year. Could the
fact that they painted the bottom of the transducer be causing this?
It worked fine the first few times I was out this year. I tried
adjusting the transducer and wiping the bottom, but didn't get and
diffeent results. I do not have a trailer, so its tough to get at the
transducer to see if it is cracked.

Also, is it common for this to fail after a season and a half of use.
I upgraded from hummingbird to eagle because they are supposed to be
the best. I called Eagle and they said to buy another transducer and
see if that works, the rep on the phone wasn't much help. They want
$80 for a new one, $89 to send the whole unit in for repair. I only
paid $135 for the whole unit!

Thanks,

Fred
