And what kind of boat & hull?
And just where is the (Airmar) transom mount t/d installed? What model t/d? http://www.airmartechnology.com/2009...ch-results.asp
And have you tried adjusting the noise suppression and gain/sensitivity controls? (On what F/F?)
Is the t/d kicked up?
You can try gently cleaning the t/d face with a Scrotch Brite pad.
