Quickly attaching a fluorocarbon leader to monofilament main line — the easiest line-to-line connection
Overlap the last 6 inches of both lines, running parallel in the same direction
Form a loop with both lines together and pass both tag ends through it — that is one overhand knot
Pass both tag ends through the loop a second time
Wet the knot and pull all four strands simultaneously to tighten
Trim both tag ends to about 1/4 inch
🎣 Pro Tip
Three overhand wraps (triple surgeon) instead of two adds significant strength for heavier applications.
