Looking for any suggestions, devices used to attempt to recover a light0action 7' crappie rod. Had a custom-built personalized rod built for my brother-in-law. It was gift during holidays. Within an hour of very first morning of use, he turned his attention to others, heard the @%$*(& leaving the boat. Crappie (or white bass) took the outfit.

He is devastated...any tools or methods to attempt recovering would totally be appreciated. 30-foot deep along bridge pylon.
