So I was able to do some side by side testing last week in a pond on the base where I work. The Berley Pro transducer plate for the Humminbird does indeed cause some interference! I know they claim that it doesn't but there are clear differences in image quality when comparing the transducer picture in the Berley Pro adapter plate and when using a transducer deployment arm. Since I have two of the same side imaging transducers I was able to simply unplug one and plug the other in to get definitive side by side comparisons while on the water with the same settings on the head unit.
I started with the transducer on the deployment arm over the side so that I could dial in the sensitivity and contrast settings to get the best possible picture. Once I had the settings where I wanted them and some solid bottom contours to look at I swapped the cables and plugged in the transducer that was installed under the boat using the Berley Pro adapter plate. I could still see the bottom contours and laydowns that I had marked previously however the returns were all much less defined. Even just the bottom (I was using the same color palette as the above example pics in this thread) went from being a strong amber return to being mostly black with just faint amber returns from hard objects. I was able to turn up the sensitivity and turn down the contrast to compensate but I'm sure there is still some loss of image quality due to the interference.
I'm undecided on whether or not I'm going to leave my transducer in the Berley Pro mount or move it over the side on a transducer deployment arm.
Thanks for confirming that, but I figured as much as there is extra material for the transducer to work through. I'm still undecided on a system, but at times I think I'm putting too much thought into it and should just get out and fish.
