I bought this primarily to humanely kill caught fish. Sometimes the fish are too big and rush around my kayak. I prefer to kill her as soon as possible for her sake and myself. This bat works great with sea fish! Aluminum means no rust. Hollow means it floats! The only problem with this racquet is that the wrap around the handle comes off quickly and the color doesn't last forever. I replaced the wrap with my own paracord grip wrap. Works great, love this thing and the cool sticker!
