What do I have here?

Hi all, I'm sure this is going to be a dumb question, but I'm new to boats and am fixing this one up. 1998 Maxum 1900XR. Around the bilge pump are 3 sensor/senders/transducers. 2 round guys to the right, a single oval-shaped one to the left. One of the round ones is damaged and the wire is smashed off of it. Are these the depth finder sensors or something else? Some pictures attached..

Yup their all depth transducers. Guess previous owners just added new ones as the old went bad.

Appreciate it! I figured that I'd better check first.

Do any of them have a spur style wheel on the underside (hull side)? That would be a type of speedo. You might have a stock depth sounder (numbers only), a stock speedo, then the previous owner added an additional transducer for a depth/display, like a fish finder.
