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.

use a heat shrink butt connector for the best sealed connection.

Recommended by Raymarine for my fishfinder is a thermal circuit breaker instead of a fuse. They are cheap even at West Marine and I like that if it ever trips I can reset it instead of being stuck on the water without a replacement fuse.
