Have you ever wondered what happens to all those golf balls that end up in the ponds, lakes and streams of golf courses? They’re not left in the water to rot for all eternity. Instead, golf ball divers retrieve them and make a handsome profit from them. A typical golf ball diver can retrieve 800,000 balls a year, or 40 tons, and make up to $100,000. The downside is that there are many dangers involved, including drowning accidents and alligator attacks.
