+1 Best unit I ever had and I had a few good ones. I wouldn't hesitate getting another one. I have the transom mount transducer and it's fine, but I'm considering a thru hull in the future. I've never had a problem with frequency interference from other boats with the 50 and 200 of the Furuno. I also have never heard anything negative about a Furuno which is why I chose it. I can't say that about other FF's. Not saying others are not good or anything so I hope no one takes that the wrong way.
