How Fish Finder Works?

best kayak fish finder
Concerning catching fish and calculate their circumstances in water, there has no alternative than a fish finder. The fish finder is a high methodology and technical instrument, which is used for researching the underwater object and fishes.
Countless people don’t know how a fish finder works exactly? Therefore, let me clarify your valuable issue.

Sonar operating

A fish finder is all about sonar technology, from World War 2 this technology has been using for finding underwater fish. First of all, while you’re on the water and your machine is switch on, it will produce a sonar line in the water.
If there has a fish, sonar will be a return to the machine again quietly. For instance, you will get the information about how big that fish is and how much distance it has.

Cone angle

Fishfinder works magnificently to find the cone angle of a fish. The cone angle in fish finder defines how much depth, far, and degree standing of that object. For example, 20 degrees cone angle means 0.35 or roughly 1/3 of depth.

Fish target

Obviously, it’s very tough to target the fish in deep water. But fishfinder makes it straightforward to target. It doesn’t matter how much deeper the fish is; fish finder will easily target it and will inform you of its distance.


The transducer is wherewithal, which sends the sonar signal in the water by the wire. Also, it assures the fish distance, depth, condition, and angle. Overall, you can say it plays as the signal communication between the fish and the machine.

Plankton, Aquatic plants, rare creatures

Fishfinder also works to find plankton, aquatic plants, and rare water creatures. Reducing the sonar power single, water substance will absorb the sonar signal and will help you find those objects correctly.

What to Look For in a Kayak Fish Finder?

Different fish finders are out there with different characteristics and numbers. The abundance of information is easy to confuse.
Here is a list of features to consider before purchasing a best kayak fish finder. The right fish finder may amaze you with its characteristics and a great way to catch plenty of fish!

1. Size of the Screen:

The screen size is an essential factor to consider when picking the most trustworthy fish finder for your kayak. A general rule is to purchase the largest screen size that fits your budget.
On a larger screen, you see more data immediately. Since the kayaks are not so big and close to water, you have to take a more petite screen.

2. Quality of the Screen:

Try to check the screen quality. The screen pixels determine the quality. You can think of a pixel as a dot on your screen. Thus, the more the pixels, the more accurate display you will have.
Never compromise the quality, even though you will get a large screen with low budget. Even if you opt for more affordable fish finders, look for fish finders with an excellent screen resolution.

3. Types of the fish finder:

There are two different types of fish finder out there, permanent and portable.
  • Permanent fish finder: You can connect the permanent one to larger kayaks. 
  • Portable fish finder: On the other hand, a portable fish finder can be the right choice for a small kayak. With a portable fish finder, you can fish of many kinds. It is also the best choice for boat rentals. However, it is light enough, and so you can quickly move it around on the boat.

4. The number of Frequencies:

Most inverters work well with two frequencies. Generally, the higher frequency produces a sharper and more detailed panorama of your screen.
The sonar pulses depend on the frequency of the transducer. The higher the frequency, the higher the sonar pulses.

5. Power:

If you’re on a tight budget, always choose fish finder that is high in watt. You can check this some expensive fish finder here: It will help you take measurements faster.
The fish finder of low power emits waves very gently and is not as secure for deep-sea fishing. Yet, if you only want to fish in shallow water, a low power fishfinder is fine.

6. GPS:

Global Positioning System or GPS is an essential function while kayaking. A GPS device can track your journey and protect your preferred fishing spots. GPS is also more critical for kayaking fishing than land fishing.

7. Bright Sunshine:

When it comes to finding the choicest fish finder, you have to consider the actual fishing conditions. The bright sunlight makes the fish’s screen challenging to read.
You can utilize multiple LCD strips, which can reduce glare. You can even purchase gloss-resistant displays.

8. Transducer:

For fish finders, the transducer is a vital part. What is the transducer? They serve as transmitters, and receivers of sound waves also detect sonar waves reflected from various objects. Moreover, each signal’s output has come in a graphical form.

9. Waterproof:

The right fish finder must be waterproof. Contrarily, the water will destroy it. And so, you have to ensure that your fish finder has excellent water resistance.

10. Price:

Choosing a top kayak fish finders only for the price is a great mistake. Therefore, you need to ensure you don’t negotiate on core features at an affordable price.
Screen, sonar, GPS, and power performance are key factors to think before making a final decision.

How do you power a fish finder on a kayak?

For powering a fish finder, at first, you have to mount it. Most kayakers mount the fish finder upfront. Some kayakers place them on a pivot arm that can be pulled back when unused.
Your transducer has specific needs, and your safety needs to read the complete package insert that you receive with your fishfinder. For correct operation, lateral transducers must have an entire cone vision (transducer shapes).
More kayaks are shifting to rail-mounted side control arms. It is not only practical but also allows you to transfer the entire system to another kayak with a track.
And guess what?
To power-up, you need 12 volts. If you spend a little time fishing and never give more than six to seven hours in the water, a seven amp battery is usually fine.
If you want to spend more time in the water also leaving the fish finder most often, consider a 10 to 20 amp battery. You can put the battery in the kayak and run the cables through the case.
But with the batteries like new YakPack, ONE can place the cables on top of the power source and take them out and use them in the other place.

How Do You Install a Kayak Transducer?

The transducer installation is part of the installation of the fish finder for a kayak. However, you can carefully follow the sensor installation instructions in the booklets provided by your model to get how you will place the transducer on the kayak hull.
So How to Install a Fish Finder on a Kayak?
At first, remove all the seats from the kayak. Then turn the kayak to find the flat part of your hull. There you have to place the transducer so that it is easy to reach.
Rub the surface lightly and then wipe the surface with a cloth before application. Use silicone-based adhesive for covering the base of your transducer without internal air bubbles. It will support you with bumps, waves, and different movements.
Set the transducer in your hand by pushing it down and rocking it back and forth slightly until it rests entirely against the body. However, it is the most straightforward kayak converter support system you can follow.
The installation process should also have views on the protection of the transducer in the kayak. Transmit some area between the transducer and the bracket for it to work correctly.
Now place the weight on the transducer to press it down and dry for around 24 hours.

How long will a battery-run a fish finder?

When fully charged, the battery provides 6 hours of operation in fishfinder 3.0 plus 5.5 hours in the PRO as well as the PRO +. Please note that at shallow temperatures, the battery may drain slightly faster. Charging takes about 2 hours.
In the sleep mode, fishfinder 3.0 can operate for about two months on a single charge. Also, you may find a big difference between lead-acid batteries and lithium batteries.
Lithium batteries last longer, are lighter, and maintain a more stable charge. You want to read about batteries before buying them. Lithium batteries are 2x to 3x more expensive but are worth a long time as they typically last 4x to 5x longer.
You can also use a group 27 battery, and it is 105 amps. Since most anglers use about two boosters, you can use it for 50 hours. Most kayak engines consume about 1 amp/lb at full power.
Even if you run the 50lb power motor at full power for about two hours, the battery will run out. Also, never discharge the battery below 80-50% or charge it immediately.

Tips on Installing a Fish Finder on a Kayak

In truth, installing a fish finder on a kayak is pretty incredible but not difficult. As you know kayak is tinier than other boats that’s why people take this process with tough. Indeed, I have a very simple technique and easy steps that could help you to install it on a kayak promptly.

Now cut another hole like it and keep it in front of another hole. Remember; don’t hole the crucial part of your kayak. Find out an unusual part then hole out that part.
Let’s jump to the next part:
It’s time to adjust the transducer on that hole. Before you adopt the transducer, make sure the wires are all out of the kayak hole. Otherwise, wires could create troubler to fix it.
After placing the transducer on the pipe hole, it’s time to push the pipe in the scrapper hole. One inch below in the kayak, stick or place the transducer. If you place it higher or deeper, it won’t work adequately.
It’s time to seal the pipe top with a cap. Eventually, your fish finder is all set to start and use and search the fish.


Nowadays, kayaking is becoming very popular. Most people cannot leave it for the first time after fishing. In fact, the excellent quality fish finders give you a more enjoyable kayaking experience.
