Hi guys,

My grandfather decided to pick this ol Fish Finder up off the curb while down in Florida. It seriously looks like some ancient technology! It's a Sitrex Honda HE 356A. To be honest I'm not even sure if it works, but I plan on finding out this weekend. The problem is, that there is no transducer or 12v power plug with it. It has the connections on the back of the unit for it, but he didn't see (he claims) any of the related equipment needed to make it work. So my question is: where the heck do I find what I need? I already tried ebay and the good ol google search, but haven't found any listings that are current - only archived listings. Here are some pics to possibly spur some memory or something...
