Pros: if for some reason your fishfinder were to draw extra current, you could destroy it. A 3A fuse will prevent this as only the fuse will blow.
Cons:Extra connections that could fail or become loose. Also, if you are out on the water without a spare and the fuse blows you can't use the GPS unit at all.
