During our recent trip to Raystown, my transducer got ripped from the wire... It's for an Eagle Supra ID. My real question is, can I just buy any old transducer and wire it into my existing set up. I know the connectors are different on most of the models but is the wiring usually the same?

If it's the same frequency, it can be spliced onto your cable, but you have to know how.  It also make like much simplier if they are the same type cable.  However, if you're having to buy one, why not just buy the one that fits.

I can't seem to find the one that goes to it. I sent an email to Eagle to see if they had them; no reply yet... I was just looking on ebay to see if they had them and saw a ton of lowrance ones, that's why I asked. I should just buy a while new sonar
