transducer question

My ten year old Eagle depth finder ,finally craped out.I glued the transducer to the hull and it worked fine. I'm looking for a new simple depth finder, but I need to know ,can you mount any transducer to the hull ?The unit I'm looking at doesn't say.

    I’m not sure of your question. Generally there are three types of transducers; a thru-hull, a shoot thru, and a transom mount. The thru-hull requires cutting a hole in the bottom of the boat…I assume you are not talking about this. The “shoot-thru” type is epoxied / glued to the interior hull. The “transom mount” is affixed to the exterior of the transom and must be in direct contact with water to work.
    So…Although I have not attempted it, the transom mount cannot be epoxied to the interior of the hull. Most of the more simple units will come with a transom mount transducer, a shoot-thru type will probably have to purchased separately.
    Hope this helped.

    Yeah, I'm talking about a shoot thru.That"s what I have now.

    Why do you want a shoot thru and not a transom mount?

    It works better at high speed and in a rough chop.

    Most come with transom mounts. Possible you can find one that will work on eBay or Amazon. Just gotta have the correct mhz I believe. Added cost though.

    No water temp though. My old boat had a shoot thru. I really don't remember it performing any better at hi speeds or chop.

    I have epoxied transom mount transducers inside the hull on two fiberglass boats. They worked with no problems and were more reliable than when they had been mounted on the transom. I'm not sure that a side imaging transducer would work epoxied into the hull, but the simple ones I used worked fine. I only used them for depth.
