Prefishing has helped me a lot. It gets me mentally prepared if its going to be a tough bite so I have more patience in an area where the fish have been. Also if anything I want to know what color the water is,is it droping or riseing. What is the temp? I want to know what the bait is doing. This kind of info helps me elinamate rods and baits.Then if things change on tournament day(they always do it seems)I am in a better position to make decisions on what to do next. My partner used to not beleive in prefishing i.e. soremouth them,he knows the lake,he knoes what they should be doing this time of year.Yea,Yea,Yea. He knows better now.
