The secret of flashers lies in the mechanisms salmon use to find their prey. Salmon, like other fish, have five sensing mechanisms they use to find their prey. Sight, smell, sound, lateral line vibration sensors and electric field sensor cells which can detect nerve pulses emitted from bait fish. The lateral line is by far the most important of these. Along a salmon's side and on top of his head he has rows of nerve cells that can sense vibrations in the water. When a school of bait fish swim above a salmon he knows exactly where they are even though he cannot see them. He can sense the vibrations of their wiggling tails as they swim. He can also detect the stronger vibrations made by larger fish as they attack bait fish. If you watch the action of a flasher in the water its tail kick closely duplicates the swish swish of a salmon's tail as he attacks.
Salmon sense this from as far away as thirty or forty yards and will immediately charge in the direction of the flasher. Like a magnet, the flasher has pulled salmon
to your baits and lures. This is the flasher secret. It pulls salmon to your boat. You may catch them on the setup behind the flasher or you may catch them on other
lures fished above or to the side of the flasher. No other device offers the lateral line attraction of the well designed flasher with its strong tail kick imitating an attacking salmon.
