Definitions of leader
Top Definition

1. In conventional fishing, the very terminal end of your line, where the fish does business. It can be wire where needed for toothy critters, or a mere gossamer thread when fooling wary trout.

2. In fly fishing, the clear tapered monofilament leader distances your highly visible fly line from the fish, and also dissipates the energy at the end of cast.
