Transducer question

[LWinches]

I guess like most I've gone through a few fishfinders.

Part 1.
Recently I decided to cut apart a Humminbird Dualbeam plus transducer and see what was under all that plastic and epoxy. It's a 200 Khz and 83 Khz transducer. It was interesting. I found one ceramic element with two wires attached to the surface. Then I remembered reading about the Lowrance Broadband and how they pass 83 Khz through a 200 Khz element to get what they call a 120 degree cone.

Part 2.
Then I took this Humminbird ceramic element and compared it's size to the elements in my Vexilar Edge 3. They are 107 Khz and 400 Khz. I didn't use a micrometer but the best I could tell they were of identical size.

Apparently the physical size of the ceramic element has little to do with the size of the cone. The size of the cone must be some dependent on the crystal and the frequency passing through it. I didn't find a crystal though. Maybe I didn't know what to look for.

Now the question.
If I hook up a Humminbird 455 Khz 45 degree cone transducer to the Vexilar 400 Khz transmitter, what will the size of this cone be? Secondly, does anyone know the pinouts and color code for a Humminbird Quadrabeam transducer? The Quadrabeam has 83, 200, and 2-455 Khz beams.

BTW I ordered one of the Lowrance HDS-5X to try. If it doesn't give me the look I want of the bottom, maybe I'll try it out with some of these other transducers.

Thanks to all.
