Just put one on the bow of my boat striker 7cv. Really like the dv picture, temp and depth are very close to my Lowrance hds8 close enough that I know it is just the difference in transducer depth. But I am having interference when I tap on my tm. The wiring is to a seperate fuse panel so I do not know if I need to put a piece of thin rubber between the transducer. First time out with it yesterday and think I am going to like it.
