There is soooo much mis information, partial information, overly general information out there that its very hard for a new fisherman to quickly get on fish, and it's very frustrating.
The number one thing is to fish areas of structure such as reefs or sea grass, hunt edges of everything (edges of oysters, edges of grass, edges for channels, etc etc. and look for signs of life such as baitfish or shrimp etc etc. Add some current due to tide, wind, or man induced and now you're starting to simplify all the fog of the vagueness. Read every article in quality magazines such as Texas Saltwater fishing Magazine.. have you heard of TroutSupport DVDs... do a search for testimonials for those and see what people say about them... if you feel like you don't mind the risk (and they have a 100% garantee) then invest in educational tools like that. Go with guides every chance you get and go with fishermen that are better than you.. sometimes that's hard to tell. Many talk a good talk but less actually know what they are doing. Get references about anyone before you go with them, find our if they are good by asking around. Get information local to where you are.. ie a Texas product or something made that will work in Texas by a Texas angler. Rods, reels, gear... even the worst crap in the right hands with knowledge will catch fish and the best of the best equipment might as well be bricks in the wrong hands without the right knowledge how and where to fish. Lures... any lure will catch a fish with the right knowledge, there are no magic lures but some are built for certain tools and have better quality for the salt than others.
