Back in July my father-in-law dropped one of my downriggers overboard in the Whittier Harbor. Oops. I spent a couple of hours trying to hook it via various means to no avail, but we eventually decided to salvage the day and head out anyhow.
I have a friend who has offered the use of his scuba gear to go retrieve it, and now that the water should be getting clear I figure it would be a pretty reasonable proposition. That said, what are my chances that it's worth salvaging after 4 months on the bottom? It's a Cannon Unitroll 10 - about $300 new. I figure it'll cost me $50 in gas round-trip, $12 for the tunnel, and half a day of my weekend time. If it would be fully functional, that's likely worth it, but if it's got plenty of metal on the inside that is likely to be corroded, well... Any words of wisdom?
