It has a nice list of equipment for both fly and spin. I didn't have much luck from Belizean Shore's dock, but did find a spot just north of the dock that holds fish. Walk about 50 yards north up the beach, about 15 yards out it drops off, there use to be a post sticking up, but don't know if it's still there? Got a couple nice barracuda at that stick. Remember to use wire leader. If you get a chance go out with a local guide, it's well worth it.
