Leaders

• The swivel is commonly used for attaching leaders to the fishing line. The swivel requires one permanent knot and allows the angler to change the leader by unhooking and hooking the swivel. You do not need any other knots once the swivel is attached to the line. The leader provides enough separation between the swivel and the bait or lure conceal it from the fish.
  
  

Baits

• The swivel allows the angler to change baits at will. You can use the swivel to attach leaders with pre-rigged baits to the line. Attaching the baits without the use of a knot saves time and makes it much easier to fish in low-light conditions.
  
  

Lures

• Lures can be attached directly to the swivel or through the use of a leader. Some anglers believe attaching the lure directly to the swivel reduces the motion on the lure but many anglers believe it does not effect success. If the angler does not wish to attach the lure directly to the swivel, it is easy to a attach a looped leader to the swivel and attach the lure to the leader.
  
  

Significance

• The swivel is an excellent fishing tool that is not necessary but does save time and reduce the need to clip the line. Although the swivel comes in many shapes and sizes, the only important factor is the strength. The swivel must be strong enough to withstand the resistance of the largest fish you will catch.
  
  

Expert Insight

• Use the swivel as a standard piece of equipment, but do not resist removing the swivel if the fish are being selective or spooky. The swivel adds a shiny, metallic element to fishing and can be obtrusive in shallow, flat water. Remove the swivel when fishing over spooky fish.
