The first thing in a fly fisherman's bag of tricks is waders or hip boots -- what he'll wear to more easily maneuver the currents of a river, stream, lake or ocean. Whether you want waders or hip boots depends on where you plan to fish. Obviously, if you have your eyes on a deeper river or stream, you'll prefer chest-high waders to be sure water doesn't seep into your socks. Some waders are ankle-tight, which means they provide support to your ankles, and the tighter fit prevents blisters. The downside is they're difficult to take on and off. Waders are either stocking-foot or boot-foot. With stocking-food waders, you'll need to slip on a separate boot over your waders. Most boot-foot waders have felt soles, so you won't slip when you're walking around in the water on the rocks and other precarious surfaces.
You'll also need the obvious: rod, reel, line and fly. Because your line needs to be heavier than your fly, you'll need to work backwards from your fly to determine what type of line, rod and reel you'll want. As Dave Hughes, author of "Fly Fishing Basics" explains, you'll decide the type of fly you want based on what the fish eat. The line must be heavy enough to carry your fly gracefully over the water. And the rod and reel must be able to properly handle the weight of your line.
You might also like a pair of polarized glasses, which reduce glare and help you to see the fish beneath the surface of the water. Most fishermen also wear fishing vests, and you'll need a bag to carry your boxes of flies, flashlight and other miscellaneous tools.
