FF = Problems??

The first fish finder I had, I could only see the bottom only with nothing in between. No bait, no kelp.... I also used Marine goop. After that I switched to Ace two part epoxy for plastic.

the difference is that the goop is soft and dampens the signal. Epoxy cures harder and gives you better resolution. But the hardness is also the draw back as it can become brittle and break off. So what I did was use some adhesive putty and formed it into a circle around the location I planned to install the transducer. Then I filled the circle with epoxy and installed the transducer. Of course avoid bubbles and use a weight to sit ontop of your tranducer while it cures. But this has worked perfectly for several years now.

The epoxy thing is nothing new, nor is using a well, but do a search on the different boards and you'll see a number of ways to do the same thing.

On an Extreme this process is even easier. once you shave the foam out from inside the hull you alread create a nice well for the epoxy...

The difference in what you can see between epoxy and goop installations on the fish finder is dramatic, well worth doing.
