DIY General • Fitting transducer on a Viking Nemo

[Toffeeboy]

Hey All,
Just after a few tips / photos how to fit a transducer in the hull of my nemo. I was about to glue some foam to the hull, with a cut out for the transducer to be sealed in. I feel that the hull is not completely flat and was worried about losing the effectiveness of the transducer. Any suggestions or photos would be great, thanks in advance. Toffeeboy
