Humminbird Transducer clicking HELP?

[Slappy]

I just transferred my transducer from one yak to a new one. The transducer was installed with epoxy and after an hour of heating and chipping at I got it clean ready for install. I just mounted it again with epoxy (No Bubbles great picture) and when I fired it up during my mackerel lobster bait trip it sounds like a ticking bomb is beneath me.

Any insight? Does anyone else have a ticking transducer. I know the transducer pings but I never thought it was audible. I'm worried it might effect fishing.
