Default Thru-Hull Transducers

I don't know much about them.

I keep my boat moored at a freshwater marina in Canada and my transom transducer (which is hard to get at while moored) gets pretty scummed up and screws up my finder.

I'm wondering if these "Thru-Hull Transducers" might be the answer. What is the down fall? do they read well as any other?

Also, I'm looking to spend $1500-2000 USD on a GPS/FINDER. I like Lowrance. Had an LMS ??? (can't remember). I'm interested in Raymarine too. Anything I should know? suggestions?

Thanks.

The Thru-hull is mounted outside the hull "Thru" the bottom. It sounds like you might need an In-Hull transducer which is mounted inside the boat on the hull. The transducer is able to transmit it's signal thru the hull and into the water with a slight loss in performance. Many people like this type because as you said, it does not get fouled, it does not create drag or turbulence, and if you bounce a log, rock, or anything else along the bottom of your boat it wont get ripped off. Downside is the slight loss in performance. It won't work too well with a cored or wooden hull (if at all).

They also make a $pecial type of water based antifouling paint just for transducers which won't damage the plastic.

As said thru hull , you would have the same problem.
The next type is shoot thu the hull. It is mounted inside the bildge in a tank with mineral oil
in the tank.
Tempo makes the antifoul for transducers. I saw it today in the boat store. It comes in a
spray can.

I couldn't remember who made it when I posted, but I found it. Its made by MDR and is called "Transducer antifouling paint" (go figure). It comes in a 2 oz white plastic bottle with a brush built into the cap. I put several layers on the transducer and don't have a problem all year. Should be a little less than $10.
