Say what you want, this fly catches fish, developed in the UK in the 50?s.
The booby is a trout fly that has two very large round eyes made from buoyant foam. They’re large and round, so I guess you can use your imagination to figure out how they got their name.
The first rule about fishing a booby, please debarb the fish eat this fly and swallow it, that's why it is banned in most angling tournaments.
The reason it’s so effective is the movement it gives and the variety of ways this fly can be fished. It moves up and down the water column staying in the zone for the maximum amount of time.
