Instructions
Start "Rapala Pro Bass Fishing" and, preferably, load a saved game in which you have completed multiple challenges and missions. Each time you complete one, you will unlock additional equipment to purchase, including new fishing rods.
Press the "X" button on "Shop" in the main menu to enter the game's store area. All of the items you have unlocked will be available for purchase in the Shop menu. By default, the fishing rods tab will already be selected.
Scan through the list of available rods and press the "X" button twice to purchase one of them. Once you've purchased the rod, you will need to equip it to your character.
Navigate to the "My Equipment" option in the main menu. All of the equipment you have purchased or won will be displayed in tabs, and the tab for your fishing rods will automatically open first.
Select the rod you want to use and press the "X" button to equip it. The rod will then be equipped to your character for all future fishing excursions, unless you equip a different rod to him.
