Hello "Dink," I am 15 years old (probably not much older than you) and have been bass fishing since 8. Now looking back I feel like I pretty much wasted my time in my first few years bass fishing, because I just went with random lures that I thought looked cool. But, then from 10-12 I started to acquire more knowledge and get a lot better. The more you practice the better you will get. Then in the last few years 13-15 I have acquired so much bass fishing knowledge from videos, experience, and older men and now I know so much about bass fishing and how it all works. The more you fish the more you will figure what colors work in certain situations, what lures work at different times of the year, and how fast or slow to work the lure, and how deep or shallow the bass are located depending on the year time. My 2 best tips to you are to get experience, experience, experience, and to ask questions from older people who have been doing this for a long time. This website, and any old joe u meet on the bank are probably good places to start. As far as lure, I have used well over 50 lure models in the past 7 years and have narrowed it down to what I really ever throw. Those are my confidence lures. I really only use 5-10 different lures per year and I fish like half of the whole entire year. Last year, I caught 300 bass over 3 pounds and caught about 10 that ranged 7-10 in my life. This isn't bragging, this is showing you that the longer you wish, the more confident you will become in certain lures, therefore you will probably start catching bigger fish. So, figure out what your confidence lures are, the more lures you use, the more you will learn to see which ones you like best. Here are 10 cheap reccomendations:
