When it comes to the captivating pastime of magnet fishing, a solid knot is indispensable. The durability of your knots can mean the difference between landing an exciting find and losing your magnet, an event that would certainly cast a pall over your outing. Consequently, understanding how to tie suitable magnet fishing knots is an essential skill for any avid magnet fisher. This guide will walk you through some of the best knots for magnet fishing, their unique features, and instructions on how to tie them.


Crucial Knots for Magnet Fishing

A handful of knots have proven especially effective for magnet fishing due to their unique property of tightening on themselves under load, providing a secure hold on the magnet and the capacity to bear heavy weight. Among these are the Double Figure 8 Loop, the Uni Knot, and the Palomer Knot.

Double Figure 8 Loop

Revered as the holy grail of magnet fishing knots, the double figure 8 loop guarantees near-total security for your magnet. This knot's strength stems from the fact that the more tension applied, the tighter it gets. It's an evolution of the figure 8 follow-through loop, yielding a robust knot with a slim chance of losing your magnet. Furthermore, it is relatively easy to tie and forms a straight loop. However, its downside is that it can be challenging to untie.

How to Tie a Double Figure 8 Loop

  1. Start by making a loop with the rope.
  2. Thread the end through the loop, forming an 8 shape.
  3. Feed the end through the 8 shape.
  4. Open up the end loop, bring it to the front, and then pass it through the right.
  5. Tighten by holding the end.
  6. The end result should resemble bunny ears, hence the nickname.

Uni Knot

The uni knot, also known as the Hangman’s knot, is an uncomplicated yet reliable knot. Given its simplicity, it's a popular choice among magnet fishers. This knot is ideal for larger diameters, often encountered when fishing for large items or when employing hefty magnets. It retains much of the rope's breaking strength and can withstand not only steady pressure but also sudden jerks.

How to Tie a Uni Knot

  1. Pull the rope through the magnet hole.
  2. Double the line back so it is parallel.
  3. Lay the tag end over the doubled line to form a loop.
  4. Make six more rounds around the double-backed line with the tag end.
  5. Push the tag end through the loop.
  6. Pull the end through the loop.
  7. Finally, slide the knot down to the hole.

Palomar Knot

The Palomar knot is a sturdy contender, boasting the potential to be as strong as the rope itself. It's popular in fishing due to its efficacy in tying on hooks or swivels, but it has a reputation for being slightly more challenging to tie than the Double Figure 8 or Uni Knot.

How to Tie a Palomar Knot

  1. Double about 6 inches of line and pass the end of the loop through the hole of the magnet.
  2. Tie a loose overhand knot.
  3. Hold the overhand knot between your thumb and forefinger.
  4. Pass the loop of the line over the hole.
  5. Slide the loop above the hole.
  6. Pull on the hole of the magnet and the standing line to tighten the knot.
  7. Finally, tie an overhand knot with the double line.


When tying the Palomar knot, ensure all parts of the knot cinch up together when the magnet is pulled through the loop to avoid failure.

Knots to Avoid

Despite the multitude of knots available, not all are suited for magnet fishing. Some notable knots to avoid are the Portuguese Bowline knot, the Overhand knot, and the Square knot. These knots can easily come loose or break under strain, jeopardizing your magnet fishing endeavors.


In conclusion, a strong, secure knot is vital in magnet fishing. By mastering the art of tying the Double Figure 8 Loop, Uni Knot, or Palomar Knot, you can be confident of a successful and rewarding magnet fishing expedition. So, go ahead and try these magnet fishing knots for a firmer hold on your precious finds!

  • What is the best type of rope for tying knots and magnet fishing?

    Most ropes supporting about 250 lbs. or more, commonly found in hardware stores or fishing aisles, should be adequate for magnet fishing. The appropriate rope will also depend on your magnet's weight, with heavier magnets necessitating stronger ropes. Some popular options among magnet fishers are paracord and braided rope of various strengths.

  • What is the strongest knot?

    The Palomar knot is often touted as one of the strongest knots. When tied correctly, it maintains nearly 100% of the original line strength. This knot is great for applications where strength is critical, such as magnet fishing or climbing.

  • How do I ensure my knot is secure?

    Ensuring your knot is secure involves a few steps. Firstly, you need to choose the right knot for your task. Some knots are better suited for certain tasks than others. Secondly, you must make sure to tie the knot correctly; mistakes can reduce knot strength significantly. Lastly, always test your knot under tension before relying on it. If the knot slips or deforms under tension, untie it and try again. Also, ensure there is enough tail (the end part of the knot sticking out) left after the knot is tied, as a short tail can lead to the knot unraveling.

  • What is the easiest knot to tie and untie?

    The Square knot (also known as the Reef Knot) is one of the simplest knots to tie and untie. It's made by tying a left-handed overhand knot and then a right-handed overhand knot, or vice versa. While it's easy to tie and untie, it's not suitable for heavy loads or critical applications, as it can easily come undone under strain.
