Called BPS knoxville today to find out about a Humminbird transducer. One unit, 2 transducers. Was adamantly told that" they don't make those, I've never seen or heard of one".I said thanx and hung up. stopped at another place along the way in Perry, GA. (exit 136, I-75) and found a catalog with my desired part listed inside. Hmmmm. So I told the counter person about how I would probably have to order it online. He goes in the back and comes out with it in his hand. As soon as the Ice Queen quits blowing 30 degree wind at me I'll rig it up. Johnny Morris don't get much for the money he pays for his sales help.
