If you're going to do any magnet fishing, you'll need the correct carabiner
  for the task. There are two fundamental styles to select from: figure 8 loops
  and the UTOMAG. If you want a robust magnet carabiner that can withstand high
  pull-out forces, go for one constructed of aircraft grade aluminum alloy. This
  material is light and resistant to abrasion and water. It has a maximum weight
  capacity of 150 pounds.
    
Loops in Figure 8
  When magnet fishing, one of the most essential things to remember is to tie a
  tight knot. You might grab a big underwater item or lose your magnet if you
  don't make a strong knot. The figure 8 loop is a popular magnet fishing knot
  because it is simple to make and strong enough to retain a big magnet. The
  hangman's knot is another name for this knot. This knot is ideal for fishing
  large magnets and items since it keeps the rope's strength even during jerks.
  Make sure the rope you're using is sturdy enough to safeguard your magnet. You
  should get a rope with a tensile strength of 2,000 pounds. It's sturdy enough
  to keep a magnet in place, but it'll break if it's not strong enough. Before
  storing the rope, it should be clear of any rotting places. A faulty rope has
  the ability to break your magnet.
  The double figure eight loop is more powerful than the single figure eight
  loop. Once attached, it is tough to unhook. It will also capsize if the pull
  is from the incorrect end. Double figure 8 loops are less prone to come undone
  and are simpler to knot. They are also quite tough to untie. If you need a
  robust carabiner for magnet fishing, this is the one to choose.
  The rope should be long enough to easily pull a hefty safe while still having
  enough of length. Choose a rope with a diameter of 8mm. An 8mm rope can draw
  450 pounds, and a 20-meter rope can get you started fishing. You should also
  choose a static rope since it will not stretch out while pulling a hefty safe.
Carabiner UTOMAG
  A magnetic rope carabiner is an excellent technique to prevent the weight of a
  huge fish from sliding off the line. With a maximum weight capability of 660
  pounds, this sort of rope is lightweight and robust. To avoid corrosion and
  water damage, the rope ends are encased in strong plastic. Furthermore,
  magnetic rope is simple to tie using carabiners.
  To use a UTOMAG carabiner, tie a knot in the rope first. Make certain that the
  knot is sturdy and secure. The rope end of the carabiner should also be tough
  and resistant to wear and strain. You may also use the rope and magnetic
  carabiner as a hoisting rope for big goods. The rope is available in two
  colors: red and black. If you don't want to wear a black or orange carabiner,
  you may substitute a black rope with a silver carabiner.
  A rope made of high-quality polyester may be used instead of carabiners. It
  has a length of 64 feet and a thickness of 1/4 inch. The rope is strong enough
  to raise a weight of 250 pounds. Furthermore, the rope is simple to knot and
  can be simply packed in a compact compartment. Furthermore, it is affordable.
  Despite its exorbitant cost, the UTOMAG carabiner is an excellent purchase for
  any magnet fishing aficionado.
  To use for magnet fishing, you should consider using a rope composed of robust
  materials. A good rope should be able to withstand the weight of the magnet
  while maintaining its form. You may choose from a number of colors and styles,
  as well as patterns and materials. Choose the one that best meets your demands
  and fits your budget. UTOMAG carabiners are composed of nylon and polyester
  and are resistant to water, chemicals, and rotting, in addition to
  high-quality ropes.

Tried and true.
  Carabiners were compared based on their open and closed gate ratings. The
  closed gate rating was 11% higher than the open gate rating, whereas spine
  strength was 8% lower than the open gate rating. In contrast, key gate
  carabiners often fail at the gate's end, but wire gate carabiners typically
  fail at the base of the spine. Carabiners with key gates, on the other hand,
  were almost useless since the keys were bent in the open position.
