If you're talking about a fishing rod:
* Fish: You can absolutely catch fish with an old fishing rod! As long as it's still in good condition, there's no reason it can't be used.
* Memories: An old rod can bring back memories of past fishing trips.
If you're thinking more metaphorically:
* A cold: You can "catch" a cold, which is sometimes called catching a bug.
* A ride: You might "catch" a ride if you're hitchhiking.
* A break: You might catch a break if you're lucky.
