Review on Humminbird XP 20 Puck Transducer Car & Vehicle Electronics by James Dominick

I did not open this item because I was told by my boat manufacturer that it would not work on my boat. According to Carolina Skiff customer service, this transducer will not work in any of their skiff hulls because these boats ride on a cushion of air bubbles. In the presence of air bubbles under the boat, the signal from this transducer will penetrate the hull but not the rough water beneath the boat. If you have a Carolina Skiff, do not purchase this item. I think I'll try to sell mine.
