Mackinaw have the same ability. My understanding is they have a vision set for daylight and another for dark. Twilight is when they really can only see shapes since they are in between vision sets. This is why swinging flies and lures at dusk or dawn produces fish that might not bite if they could see your presentation more clearly. ![[Image: bobwink.gif]](http://www.bigfishtackle.com/images/gforum/bobwink.gif)
