[QUOTE="Macintosh, post: 496482, member: 31571"] why wonder? SOP for installing a shoot thru transducer is to test it before epoxying down. Use a wax toilet ring or modeling clay or something like that to create a Pool inside your hull where you will put the transducer. Fill it with water. use a sand bag or a brick or something to hold the transducer agsint the bottom in position, and test it. You will get more or less exactly the performance you will get if you do a good job epoxying down (ie being careful not to trap air in the epoxy or under ducer). I've never tried it in an aluminum, but some people say they have used the standard transducer with good success as a shoot-through. When you find the best location, then you thoroughly clean before epoxying it down. What I have been told is that you can expect worse sensitivity than if it was on a glass hull or in the water, and that the biggest issue is flexing in the aluminum potentially separating the transducer from the hull over time, potentially fairly quickly on a lighter-weight hull. And side imaging/down imaging is a total no-go if you want the resolution you expect from those types of sonar. [/QUOTE]
