To maximize its effectiveness, a flasher should be positioned about 18 to 24 inches away from the lure. This distance ensures that the flasher's actions and vibrations attract the attention of nearby fish and redirect it towards the lure. A flasher serves as a visual attractant by producing vibrant flashes and simulated movements, while the lure provides the necessary bait or imitation to entice the fish to strike. By placing the flasher within this range, it creates an enticing display that entices fish to investigate and increases the chances of getting a bite. This optimal positioning allows the flasher to do its job effectively without overwhelming the lure. Keep in mind to adjust and experiment with the distance based on the specific conditions and the behavior of the fish you are targeting.
