[Public-List] Transducer issues

 Significant fouling will interfere with the operation of the transducer. I found this out on a Fall Cruise trying to get into San Domingo Creek near St. Michaels, and having  a heck of time reconciling the chart with the 60 feet of water the depthsounder was measuring. I dove on it and found an inch of barnacles and sundry growth covering the transducer. Cleaning off restored the function.

With your glassed-in box you may be shooting through the hull through a water or oil-filled chamber, with the transducer fully inside the boat. The fouling interference would be the same.

I can recommend Patrick McMahon, Patrick at diverforhire.com   - he has a website www.diverforhire.com.

Subject: [Public-List] Transducer issues

Hi All,

   I purchased Hull #76 a few weeks ago.  I am trying to sail it to Gloucester, Va to get it closer to home. The current problem is that the depth sounder isn’t working. It is a Lowrance X47EX. I tried resetting the unit per the Lowrance Tech’s intructions. This didn’t resolve the issue. The transducer is in a glassed in box on the port side forward of the drawer in the port settee. Adjacent to this box is an abandoned valve that is in the open position. There isn’t anything connected to this valve, but due to its location and vertical position, I think it is / was a thru-hull. I would prefer not to have the boat hauled just to assess the situation and decide on a solution, but not knowing how the transducer is installed, I don’t dare try to remove it for fear that I will open up a hole for the water to get in and possibly end my  love affair with this beautiful boat. So to the point, does anyone know a diver that would be able to help me determine just what the situation is? I would like to cut the “box” out ( or just the transducer if possible ). The boat is in a private slip on Hopkins Creek adjacent to Essex Marina.

Thanks In Advance,

Bob Bohmer #76
