Puck on fish finder?

[hookedupf7]

When you guys say a puck on fish finder what do mean? I know it is a stupid question but I was wondering what it meant

[Sk8man]

A "puck" refers to the shape of some transducers...they can be black and vaguely resemble a hockey puck and they are mounted on the transom of the boat.
