The reason I brought the question up is that his videos show a reaction from the fish when a fisherman with a bright reel flashing was 20' away. Bright clothes showed up & were more visible to the fish than I ever thought. Bright lines are very visible from under water & leaders sometimes sparkled in the sun..This was both on heavily fished & not so heavily fished streams. Some times it spooked the fish & sometimes it didn't. Also I was surprised to learn how long it took a spooked fish to return to it's feeding lie. What's everyone s experience with spooked fish & how long does it usually take for them to come back in the waters you fish. I've seen them scoot off never to be seen again & sometimes they feed off your boots.
