Seaguar paired-loop join for similar-diameter mono/fluoro.

Seaguar Knot
For leader → tippet, leader → leader.
This card does not say how strong the knot is. A retention figure comes from a bench, in one material, at one diameter, tied by somebody who ties it all day — and the line in your hand is none of those. What it does tell you is whether the thing you have just tied is the thing the record describes.
What this plate is telling you
Seaguar paired-loop join for similar-diameter mono/fluoro.
Save this as a picture and it works with a dead signal and a nearly dead battery, which is when a joint is most often tied badly. The rest of this page — the steps, the seating sequence, the failure modes and the bench — is for the evening before.
Before you start
- ·NetKnots gives it for joining a fluorocarbon leader to monofilament line.
- ·Cut the leader to length before you start. The whole leader passes through the twisted loops, so it cannot still be attached to its spool.
- ·Make three full twists. The closed knot should show a clear figure eight; if it does not, cut it off and tie it again.
- ·NetKnots notes it is tied the same way as the King Sling, using two separate lines instead of a doubled end.
Step 1 of 4. Make a loop in the line and a loop in the leader and hold the two loops side by side, with the strand running from the left on top in each loop.

01
Make a loop in the line and a loop in the leader and hold the two loops side by side, with the strand running from the left on top in each loop.
Two loops lying together as one, the strand from the left crossing on top in both, and the leader's full length hanging free.
Letting the loops separate or cross differently, so the strand from the left ends up underneath in one of them.
Fix: Lay the loops together again and check the left-hand strand is on top in both before you twist.
Why: The two loops are twisted as one in the next step, so they need to lie the same way.
- Forced diameter jump through this family — Slips — mismatch is a different join. Do not use Seaguar as a step-down join.

Step 01 / 4
Make a loop in the line and a loop in the leader and hold the two loops side by side, with the strand running from the left on top in each loop.
You should now see: Two loops lying together as one, the strand from the left crossing on top in both, and the leader's full length hanging free.
If it goes wrong: Letting the loops separate or cross differently, so the strand from the left ends up underneath in one of them.
Fix: Lay the loops together again and check the left-hand strand is on top in both before you twist.
Why: The two loops are twisted as one in the next step, so they need to lie the same way.
If wrong: Forced diameter jump through this family — Slips — mismatch is a different join.

Step 02 / 4
Put an index finger into both loops and make 3 full counter-clockwise twists.
You should now see: Three even twists in the paired loops, with your finger still through the loop at the end.
If it goes wrong: Losing count of the twists, or letting them unwind when you shift your grip. With fewer than three the knot can pull apart.
Fix: Untwist fully and make three again, counting each full turn of your finger.
Why: The twists become the wraps of the finished figure eight. NetKnots uses three.
If wrong: Too few twists on fluoro — The join walks.

Step 03 / 4
Hold the loops open and feed the tag end of the line and the entire leader through the loop, following your finger back out.
You should now see: The line tag and the whole leader have passed through, and the twists sit loosely around them.
If it goes wrong: Feeding only part of the leader through, or going through a different opening than the one your finger held. The knot does not form.
Fix: Pull everything back out, put your finger back in the loop and feed the line tag and the full leader along the path it marks.
Why: Your finger marks the right path through the twists. Following it keeps the ends from snagging the wrong turn.
If wrong: Dry fluoro seat glazed the twists — Scored before it ever sees a fish.

Step 04 / 4
Wet the lines and pull on all four ends to cinch the knot into a figure eight, alternating between the tag ends and the line and leader. Trim both tags close.
You should now see: A tight knot with a clear figure eight shape, two short tags, and no slipping when you pull the line and leader apart.
If it goes wrong: Pulling only the line and leader, so the tags slip back and the knot closes into a lump instead of a figure eight.
Fix: If the closed knot is not a clear figure eight, cut it off and tie again, alternating the pull between tags and main lines.
Why: Alternating the pull lets both halves of the eight close evenly. The figure eight shape is the check that the twists and the pass were made correctly.

Seating sequence — where failures are born
The step list compresses the finish. Run these phases in order, one at a time.
01 Moisten
Wet the structure before any load reaches it.
Zero. Nothing tightens yet.
02 Load
Take up slack slowly until the wraps begin to gather.
Light and even — both ends moving together.
03 Dress
Watch the wraps stack in order; stop and back off if any cross.
Hold, do not pull. Correction happens here or not at all.
04 Set
One continuous pull to full seat — no sawing, no jerks.
Firm, single direction, standing line against the terminal end.
05 Trim
Cut the tag square, leaving a short stub proud of the knot.
None. Never trim under load.
Finished structure — what correct looks like

- ·Even, no crossings
Verify before you load it
Every line is pass or fail. One fail means retie — do not load a knot you argued with.

Field notes — dark, cold, gloves
- ·Retie by feel first, light second — the seat is a tactile event, not a visual one.
- ·Gloves off for the dress phase. Fabric hides a crossing wrap.
- ·Wrong twice in a row means the material or the hardware is fighting you. Change one, not your technique.
Seaguar Knot — finished-state checks, on the shared reference layout
When this family fails, it fails as these. The recovered end still outranks the name.
Seaguar Knot — what fails and what to do
Bight in the heavier leader; lighter line wraps the bight, then tucks.
- !Bight in the lighter line — the wraps have nothing to bite
- !Wraps walked off the bight instead of packed against the fold
- !Tag never tucked back through the bight, so the wraps dump
- !Fewer than three twists, so the knot can pull apart
- !Tags left out of the cinch, so they slip back and the knot closes into a lump
- !Twists or pass made wrongly, which shows as no figure eight in the closed knot

Get it right with everything in your favour0/5 clean
Good light, dry hands, a table. Until the sequence is automatic here there is nothing for the harder rungs to test — you would only be learning that difficult conditions are difficult, which you already knew.
How · Tie it, check it against the list, log it. Five clean and the ladder opens.
Nothing marked. Log it clean, or mark what happened first.
Not ideal for
- ×Extreme mismatch
- ×Primary braid-to-heavy-leader (use FG/Slim Beauty family)
Strength, and where the number comes from
Not established
Seaguar publishes no strength figure for the knot that carries its name, and no independent break test was found.
Percentages come from published tests on their own line, their own knot-tyer and their own pull rate. Yours is a different system. Treat a figure as a reason to test, not as a result you already have.
