I too used a Fishin' Buddy for a couple of years, and it has one feature that I really liked, side scan sonar that you can aim. But they are a hassle, have to pull them up to run, and evenually on a rough day mine smacked into the bottom of the boat a little hard and broke. So I got a Humminbird with sidescan, which is also real cool, especially in shallow water - I get a 45 degree view to each side.

Hard to believe I ever caught fish without all the electronics
