Back at the shack, head inside. Talk with the closer fisherman and tell him you want the rod. He'll give you the Super Rod . Talk with the other Fisherman here. He'll tell you that if you can see the same Pokemon more than seven consecutive times whilst fishing, he'll give you some Dive Balls . Sweet! Anyway; go back outside.

Tip #045: Hidden Benefit Of Chain Fishing
Chain Fishing - the art of fishing the same Pokemon consecutively - isn't just for boosting your ego or getting free Dive Balls. The more Chain Fishing you do, the more likely you encounter Shiny Pokemon ! This is one of the easier ways to get Shiny Water Pokemon, but will still require some time investment (and practice).
