This way the angler detect the presence of the fish without catching them. Every lake has a reputation. Go for the big bite in this situation. Fish bigger baits in areas known to produce solid fish. Some lakes noted as excellent smallmouth and largemouth fisheries.
Problem is, the most effective methods for catching the two sub-species are relatively different.
Pick a fish and go exclusively for that sub-species of bass. Some anglers wait until tournament time before bearing down and getting serious about the issue. This is risky business. After spending more than two decades on the pro tour I found that the anglers who consistently make it to the winners circle are the ones who utilize their practice time to the fullest. There's no substitute for going early and staying late.
