What is a Fish Finder, and Why Install One on Your Kayak?

In fish finders, sonar technology detects underwater objects, including fish. Among the information it provides is water depth, fish presence, and underwater structure. How does one work? Why would you want one?

The Importance of a Fish Finder on Your Kayak

So, why should you bother installing a fish finder on your kayak? Let’s break it down in plain English:

Importance of a Fish Finder on Your Kayak

1-Precision in Finding Fish

First and foremost, a fish finder helps you find fish more accurately. No more aimless paddling or casting your line into the great unknown. Its sonar magic can spot fish schools, individual fish, and their depths. It’s like having a fish magnet on your kayak, making your fishing game super efficient.

2-Enhancing Safety

Safety first, right? Well, a fish finder is not just about catching fish; it’s also about keeping you safe. It tells you the water depth, so you won’t accidentally paddle into shallow areas or bump into hidden obstacles like rocks or debris. It’s your personal safety net on the water.

Time is precious when fishing and a fish finder helps you make the most of it. Instead of wasting time searching for the perfect fishing spot, you can quickly identify where the action is. 

You’ll find those hotspots where fish are active, and you’ll get to know the underwater landscape, making your fishing trips super productive.

3-Adaptable for Various Fishing Styles

Whether you’re into freshwater or saltwater fishing, a fish finder is your adaptable sidekick. It doesn’t care if you’re trolling, casting, or even ice fishing—it’s up for anything. So, it’s not just a one-trick pony; it’s a versatile tool for all sorts of anglers.

One of the coolest things about a fish finder is that it gives you real-time information. As you move around, it’s like having a live feed from the underwater world. You can see how fish behave, check the water temperature, and spot underwater structures as it happens. It’s like having fish, ESP!

4-Learning Experience

Using a fish finder is like taking a crash course in underwater ecology. You’ll learn the habits and hangouts of the fish you’re after. Over time, this knowledge becomes your secret weapon for more successful fishing trips.

Nobody likes wasting bait and lures in the wrong spots, right? A fish finder helps you avoid that. You can save money on gear and do your part to protect the environment by pinpointing where the fish are. It’s a win-win situation.

Types of Fish Finders and Transducers

Before we dive into the installation process, it’s essential to understand the different types of fish finders and transducers available:

Types of Fish Finders

Fish Finder Types

1-Standalone Fish Finders: Dedicated fish finders display sonar data on a screen. They are often compact and designed for easy installation on kayaks.

2-Combination Units: These devices combine fish-finding capabilities with GPS navigation, allowing you to mark fishing spots and navigate waterways efficiently.

Transducer Types

The transducer is a critical component of the fish finder as it sends and receives sonar signals. There are several ways to mount a transducer on your kayak:

1-Thru-Hull Mount: This is the most accurate option as it involves installing the transducer through the kayak’s hull. However, it requires drilling a hole, which some kayakers may hesitate to do.

2-Transducer Arm Mount: This option doesn’t require drilling holes. Instead, it uses an adjustable arm to suspend the transducer in the water. While it’s easier to install, it may not be as accurate as a thru-hull mount.

3-Suction Cup Mount: This is the easiest and least invasive option. It uses suction cups to attach the transducer to the kayak’s hull. However, it may not be as secure or work well with all kayak designs.

Now that you understand fish finder types and transducer options let’s move on to the installation process.

How to Install Fish Finder on Kayak

Step 1: Choose the Right Location for the Fish Finder Head Unit

Placing your fish finder’s head unit is crucial for ease of use and convenience. Consider the following factors:

  • Size and Weight: Be mindful of the size and weight of the head unit. Ensure that the chosen location can support it securely.
  • Visibility: Select a location that provides a clear view of the display screen, making it easy to read data while kayaking.
  • Reachability: Ensure the head unit is within arm’s reach, allowing you to adjust or read data without straining.
  • Non-Interference: Avoid placing the head unit in a location that obstructs your movement or interferes with other accessories on your kayak, such as paddle holders or rod holders.

Remember, the right placement will enhance your fishing experience, so take your time to decide.

Step 2: Mount the Transducer

Mounting the transducer is critical in ensuring the fish finder’s accuracy. Depending on your chosen transducer type, follow one of these methods:

Thru-Hull Mount (Drilling Required)

  1. Select the location for the thru-hull mount on the kayak’s hull. Ensure it is in a spot where the transducer will have a clear view of the water.
  2. Drill a hole in the selected location following the transducer manufacturer’s specifications.
  3. Apply marine-grade sealant to the transducer’s base and insert it into the hole.
  4. Secure the transducer in place according to the manufacturer’s instructions.

Transducer Arm Mount (No Drilling Required)

  1. Attach the transducer arm to a stable part of your kayak, such as a gear track or mounting plate.
  2. Adjust the arm length and submerge the transducer into the water. Ensure it is submerged at an appropriate depth for accurate readings.

Suction Cup Mount (No Drilling Required)

  1. Clean the area on your kayak’s hull where you intend to attach the suction cups.
  2. Wet the suction cups slightly, then press them firmly onto the kayak’s hull, ensuring a secure seal.
  3. Attach the transducer to the suction cup mount.

Secure your transducer using the chosen method, and double-check for stability before proceeding.

Step 3: Wire the Fish Finder

Wiring your fish finder involves connecting the transducer to the fish finder head unit. Refer to the fish finder’s manual for specific instructions, as wiring configurations vary.

  1. Identify the cable from the transducer and connect it to the appropriate port on the fish finder head unit.
  2. Ensure that the connections are secure and waterproof. Use cable connectors and waterproof seals if provided.
  3. Route the cable from the transducer to the head unit, securing it along the kayak’s hull to prevent snagging or damage.
  4. Connect the power cable from the fish finder to the 12-volt battery.
  5. Test the fish finder to ensure it powers on and correctly displays sonar data.

Step 4: Mount the Fish Finder Battery

Most fish finders require a 12-volt battery to operate. Here’s how to mount the battery:

  1. Choose a location on your kayak to mount the battery. It should be dry, secure, and protected from the elements.
  2. Use battery mounts or straps to secure the battery in place.
  3. Connect the fish finder’s power cable to the battery terminals, ensuring a proper connection.
  4. Secure any loose cables, and ensure the battery is stable and won’t shift during your kayak adventures.

Step 5: Test the Fish Finder

Before hitting the water, testing your newly installed fish finder is crucial to ensure everything is working correctly. Follow these steps:

  1. Power on the fish finder and check that it boots up without errors.
  2. Verify that the transducer is correctly installed and submerged in the water.
  3. Navigate through the fish finder’s settings and verify that you can see sonar data on the display.
  4. Take your kayak to the water and test the fish finder’s functionality in a real-world scenario. Pay attention to water depth readings and any fish targets it detects. Now you know – how to install fish finder on kayak?
