I thought I'd ask here before shuffling off to buy one from Amazon.  I need a Lowrance HDI Transducer Model 000-10976-00.  It's the standard transducer packaged with the Elite-4/Elite-5/Elite-7 and the Hook series finders (maybe other units, too).

Let me know if you have one you no longer use or need.

And for certain smarty-pants who may read this, yes, it needs to work.
