Double Turle Knot

Attaches a fly to the leader through the eye, in line, using two turns for extra security
Also called: Double Turle Knot, Double Turtle Knot, Nudo Turle Doble, Nó Turtle Duplo, Nó Turle reforçado
What it is for
- Attaching eyed flies in line with the leader
- Fly rigs where the fly's straight presentation matters
- Tying on dry flies and nymphs with the eye turned up or down
- Situations that call for more security than the simple Turle Knot offers
- Trout fishing and other wary fish, where alignment affects strike rate
