So it's not just for figuring out if there's fish beneath your feet. Think video game. You can watch the fish and their interaction with your lure. Are they uphitting? Are they totally NOT into pink? These are questions that can be answered without a flasher, but with one, you get the answer in a matter of seconds instead of a matter of hours. And those times when they nibble so softly you wouldn't notice it otherwise, you can set the hook. It might just make a difference between a five-fish day and what would otherwise be a no-fish day.
