How to Make and Use a Fishfinder Rig: Your Ultimate Guide

Fishing is a popular hobby for people of all ages and skill levels. There’s something exciting about the thrill of the catch, and for those who love to be out on the water, it’s a great way to relax and enjoy the outdoors. However, if you’re not catching anything, it can quickly become frustrating. That’s where a fishfinder rig comes in handy. In this guide, we’ll cover everything you need to know about how to make and use a fishfinder rig to help you improve your fishing game and catch more fish.

What is a Fishfinder Rig?

Before we dive into how to make and use a fishfinder rig, let's define what it is. Essentially, a fishfinder rig is a type of fishing rig that is designed to help detect fish while also reducing tackle loss. It's a versatile rig that can be used in a variety of different fishing environments, from shoreline fishing to boat fishing, and is suitable for catching a wide range of fish species.

Making a Fishfinder Rig

Making a fishfinder rig is relatively simple and can be done with just a few materials. Here's what you'll need:

  • Braided or monofilament fishing line
  • Barrel swivel
  • Circle or J-hook based on targeted fish species
  • Snap swivel
  • Fishing sinker, weight size depending on current depth and location
  • Beads to protect the knot
  • Scissors or line cutter

With these materials in hand, you can start making your fishfinder rig, following these steps:

  1. Attach the mainline to barrel swivel with a knot. The top three recommended knots for durability are the Uni knot, Palomar knot, and Trilene knot.
  2. Cut a piece of leader line (24-36 inches).
  3. Attach the leader line to the other end of the barrel swivel using a knot.
  4. Tie the circle or J-hook to the other end of the leader line. Knot recommendations vary based on the hook you're using.
  5. Slide the fishing sinker into the mainline using a snap swivel.
  6. Add beads to protect the knot.
  7. Assemble the fishfinder rig loop.

It’s important to note that you can customize your fishfinder rig to suit your specific needs. For example, you can use different types of hooks, such as octopus hooks or treble hooks, depending on the type of fish you’re targeting. Additionally, you can adjust the sinker weight based on the depth and location of the water you’re fishing in.

Using a Fishfinder Rig

Now that you’ve made your fishfinder rig, it’s time to use it to catch some fish! Here are a few tips on how to properly use a fishfinder rig:

Choosing the Right Setup

Before you cast out your fishfinder rig, it’s important to choose the right setup. This includes:

  1. Line Type: Make sure you’re using the appropriate type of line for your fishing conditions. Braided line is great for fishing in heavy cover, while monofilament is better for clear water.
  2. Sinker Weight: Choose the right sinker weight for the current depth and location where you’ll be fishing. The weight should be heavy enough to keep your bait on the bottom, but not so heavy that it snags on rocks or other objects.

How to Cast a Fishfinder Rig

After choosing the right setup, it’s time to cast your fishfinder rig. Here are some tips to help you:

  1. Properly load the fishing rod: Slowly load the rod to the desired distance, then increase speed to reach the target distance.
  2. Release and cast timing: Release the grip on the rod at the right time and let the rig go forward.
  3. Tips for accurate casting distance: Use the proper casting form and timing, and be mindful of the wind.

Detecting Fish and Setting the Hook

The ultimate goal of a fishfinder rig is to detect fish, so here are some tips to help you do just that:

  1. Feeling for nibbles or bites: Keep your eyes on the rod tip and feel for any nibbles or bites.
  2. Importance of a tight line: Always keep a tight line to feel the fish's movements.
  3. Proper technique for setting the hook: Know the difference between setting the hook with a circle hook vs. a J-hook and use the proper technique.

Reeling in and Landing the Fish

Once you've successfully detected fish and set the hook, it's time to reel in and land your catch. Here are some tips to make this process as smooth and successful as possible:

  1. Tips for a smooth retrieval: Keep the line tight and pull back on the reel.
  2. Managing the drag setting: Adjust the drag setting as necessary to control the fish.
  3. Safe fish handling and release techniques: Handle the fish carefully to avoid injury, and release it safely back into the water.

Advantages of Using a Fishfinder Rig

Now that you know how to make and use a fishfinder rig, you may be wondering what the benefits of using this type of rig are. Here are a few advantages to keep in mind:

Reduced Tackle Loss

One of the biggest advantages of using a fishfinder rig is that it can help reduce tackle loss. With fewer snagging incidents, you won’t need to spend as much time re-rigging, and you can spend more time actually fishing.

Improved Catch Rates

Fishfinder rigs are specifically designed to target certain fish species, such as flounder, drum, striped bass, snapper, and grouper. As a result, you have a better chance of actually catching your target fish with this rig. Success rates vary, but some species have a success rate of up to 90%.

Adaptable to Different Environments and Fish Habits

Finally, fishfinder rigs are adaptable to different environments and fish habits. You can customize the rig to suit changing conditions, such as adjusting the sinker weight or hook size. This makes it more versatile than other types of rigs, which may not work as well in different conditions.


Making and using a fishfinder rig is a great way to improve your fishing game and catch more fish. By following the steps outlined in this guide, you’ll have a high-quality rig that’s perfect for any fishing environment and a great tool in your tackle box. Remember to choose the right setup, detect fish correctly, set the hook properly, and reel in and land your catch safely. With these tips in mind, you’ll be well on your way to becoming a successful angler. Happy fishing!
