I was talking to a friend in our club and he was showing me how he mounted his transducer onto the bottom of his TM. He has Lowrance units, same as i do and he told me its much clearer/better image with his transducer. I currently have the small puck style. His was like the one i have on the back of my boat, thats the 3N1 transducer. Can anyone elaborate on what transducer he might be using? He said it wasn't cheap, nor was the mount for it. And if its worth the time and money to change over to it. I cannot afford to change to the active Target, though i would love to, but not sure how affective or how well it would work, here in Florida, as most of the Lakes we fish are very shallow and weedy. If anyone could lend me some insight, it would be greatly appreciated.
