I got a Humminbird smartCast RF35 Fishfinder. Somebody had gotten this for me but never used it. It was opened to see if it worked but thats it never used. Here's a link to some more information.(RF35 :: Humminbird (http://store.humminbird.com/products/341324/RF35))
If interested willing to go money or plugs.

Here's and image.

What type of plugs are you looking for?
