Got my first fish finder. mounted on 14' Jon boat with 6hp Johnson. Worked good on my first trip ti Barkley lake. Showed a bit of clutter on high speed(if you call wide open with a 6hp fast). got home and lowered the transducer about 1/8 to 1/2 and went back. all is good now. Will give a report on shallow water performance when Swan Lake opens Mar. 15.
