The Surgeons Loop

The Surgeon's Loop is bassically a Double Overhand Knot and can be tied quickly and easily in the end of a line. It is often used to make a "Loop to Loop" connection or can also create a fixed loop that allows an artificial lure or fly to move naturally.  

Saltwater Experience Host, Captain Tom Rowland, has many applications for this knot. In an article he wrote, he says “I use the Double Surgeon's loop for my loop in my tarpon fly leaders.  I will do a double nail knot loop in the end of my fly line and then attach my butt section to the fly line with a loop to loop handshake connection.  Many people ask why I prefer this loop to the Perfection Loop (Click here to see video of Perfection Loop) 

I much prefer the Surgeons loop over the Perfection loop at the end of a fly leader for tarpon because the tag end of a Perfection loop sticks out at a right angle to the line.  When fishing for a large tarpon, we will use a leader of 12-15 feet and it is required to bring the leader all the way inside the reel to land them.  The loop will travel in and out of the rod guides many times before the final landing.  The Surgeon's loop is far smoother through the guides due to it's tag end laying parallel to the line rather than perpendicular.”-Tom Rowland

To tie this knot, follow the steps below or watch Tom’s video.

  1. Form a bight in the end of the line and tie an overhand knot.
