Power Rod

The Power Rod is an optional upgrade for Big the Cat in Sonic Adventure and Sonic Adventure DX. It is a stronger and better version of Big's normal fishing rod. It allows Big to cast his lure further out in ponds than before, thus making it possible for Big to catch fish that are further from his location.

Location
The Power Rod is located in the Mystic Ruins' Adventure Field and can be obtained at any point in the story. It is found in Big's hut in the jungle area, under Big's bed. Go to Big's hut at any chosen point and simply move his bed and the Power Rod can be obtained.
