More salmon are caught every year on flashers than any other device. The Pro-Troll flashers are unmatched in their performance and durability. Features include Pro-Troll’s new super spin ball bearing swivels on both ends and the latest ABS plastic for superior brilliance. Following years of testing and development, Pro-Troll has developed a lighted flasher series. Most fish are attracted to light. The light is water activated. It turns on when it contacts the water, and turns off when dry. It’s unique circuits flash red, white and green on both sides of the flasher. The sealed battery lasts 80 hours or more and then the light can be easily replaced. Lighted flashers and glow flashers are most effective in dim light (early morning) or in cloudy water or when fishing deep (where it’s dark).
