After you're got your rod and reel, it's now time to decide what kind of line you're going to use. There are three main types of fishing lines that you should know about - braided, fluorocarbon, and monofilament.
Monofilament is the best choice for bass fishing, especially for beginners. It comes in a variety of different colors and strengths, is fairly inexpensive, and is also stretchy.
Monofilament is preferred by beginners because it spools evenly and resists abrasion, so you won't have to worry about having a loose line.
Unlike monofilament, fluorocarbon fishing line is usually used as a leader because it's invisible underwater. The leader is the part of the line that's closest to the lure and it helps to stop the bass from seeing the fishing line.
Some anglers like to use fluorocarbon as the mainline, but beginners shouldn't worry about that.
Braided fishing lines are great because they're twice as strong as monofilament and also cast a lot further because of their added weight. Also, when working with a braided line, you don't have to worry about it getting twisted and it works wonderfully with spinning reels.
However, braided lines aren't recommended for beginners because they are fairly visible underwater. Also, due to their weight, it can be hard to achieve the finesse style of fishing beginners need for bass fishing.
As someone who is new to bass fishing, you should mainly focus on technique instead of trying to catch the biggest fish possible.
