I have a Fishing Buddy II. It is not as good as my Hummingbird Matrix unit but I have use for it. It does have a sidefinding mode but it just shows fish off to the side, not images. I bought mine cheap at a yard sale but a new unit is not real expensive. I believe The Fishing Buddy units are now made by Hummingbird. If you change boats a lot, they are worth the money, (in my opinion).
