All Anglers need ‘Tackle’, the term used to collectively describe all of the equipment used to catch fish.
Years ago, before modern manufacturing methods allowed specialist items of tackle to be made inexpensively for very specific uses, fishing tackle was made to cover a wide range of fishing situations but now the choice can be overwhelming.
The reality, though, is that you don't need lots of specialist tackle to catch fish, two rods, two reels (or even only one of each) plus a small selection of floats, leger weights, hooks, shot, line and the all-important disgorger are all you need to get started.
