Can You Have a Fish Finder on a Kayak? [Everything You Need to Know]

In commercial fishing, a fish-finder, also known as a Netsonde, is a high-frequency sonar instrument used to locate schools of fish. It sends sound waves downward and collects reflections from the water’s surface.

A sonar system sends sound wave signals down into the sea. These pulses are mirrored back to the surface as they strike objects such as fish, plants, or the bottom.

The sonar instrument tracks the time it takes for a sound wave to pass down, collide with an obstacle, and bounce back up.

But the question here is – can you have a fish finder on a kayak

For starters, of course, you can have a fish finder on your Kayak. You’ll also benefit from discovering underwater structure and bait. It will even show you huge bait schools and whether there are any eating fish nearby. Finally, a fish finder would undoubtedly offer you a competitive advantage on the river, and having eyes under your kayak will just serve to increase your capture rate!

4 Reasons You Need a Fish Finder for Your Kayak It’s interesting, right? 

Anglers who fish from kayaks often start doing so for simplicity. Can You Have a Fish Finder on a Kayak

While a fish finder may not be for every kayak angler, these reasons explained in this article present a good case for installing one. Many times bait may be suspended in the water column and can be located by the sounder.

To help you, we’ve explained the reasons in proper detail-

Temperature Indication

At first glance, the temperature seems to be insignificant. However, the water temperature can be the difference between a perfect day on the water and a central zero on the fish count during the transitioning seasons of winter to spring and summer to fall.

You can also locate natural spring-fed creeks where the water temperature changes dramatically. On power plant outflow reservoirs, you will be able to see where the temperature change happens.

The temperature is integrated into your transducer for the majority of goods. Make sure your machine is capable of reading Water Temperature. This is recorded in the Operations Manual.

You can also add more than one temperature gauge to your device. Ascertain that all necessary accessories are connected to the depth sounder.

Habitat Indication

When staring at a fish finder, habitat isn’t the first thing that comes to mind. On the other hand, strong fishers know that underwater structures, particularly those of large scale, can hold fish almost all year.

It’s essentially a fish’s home address. A giant fallen tree, an old tank dam, a crumbling house foundation, or even a roadbed may all be examples of this.

Although they are underwater, the best way to locate them is with a fish finder. Some fish finders have GPS and mapping apps, allowing you to identify these locations on a digital map.

As a result, you will step back in time. Once there, a short scan will reveal whether or not the fish are present.

Fishfinders will go as far as you want them to. What you have to do is change the frequencies.

For example, the lower the frequencies, 200-800 kHz for waters up to 200 feet deep and 80-50 kHz for waters less than 200 feet deep.

Bait Indicator

When you can’t permanently install a device on a cruise, kayak fish finders are ideal. They’re an excellent option for temporary mounting on small vessels, going on holidays, and fishing from shore.

Fishfinders use the Echo to detect objects underwater. They operate by emitting sound waves and waiting for an echo. Baitfish can appear on your screen as dashes, circles, or even only dots so that they may look close to plants at times.

A fish finder can identify water that is devoid of bait and live fish. It will even show you huge bait schools and whether there are any eating fish nearby. You will also be able to see how deep they are. And will inform you what baits and presentations are most likely to succeed.

Mark a Spot

Fish-finders will help you consider what’s in the water, what’s under the kayak, the depth, the geography and shape, and, of course, where the fish are.Can You Have a Fish Finder on a Kayak

The ability to map spots and plan a course is one of the most valuable features of modern fishfinders. You can also save a location to return to later since the GPS can map your path and leave a trace programmed into the system.

You will, of course, use your mobile phone. However, it would be more convenient to have a system that does this automatically for you.

A fishfinder, unlike a mobile phone, is not waterproof. No need to be concerned about lowering your pricey iPhone into the lake’s darkest recesses!

Installing a Fish Finder on a Kayak

Kayak-friendly units provide the most modern features in a compact size. The assembly of most kayaks is as easy as three stages.

Mount the display: Make sure you mount the fish finder board, where the casting, pedaling, or paddling does not disturb. Recall, the cockpit is packed with movement. Install out of the way the fish finder.

Arrange a power source: The heaviest gear you’ll have on the kayak is a 12 volt, 10-hour pack. Keep the battery next to the seat over the centerline. Prevent the battery from contacting the water by raising it over the hull’s rim.

Install a Transducer: A transducer scupper comes with many fishing kayaks. In or out of the kayak, the transducer may be installed. This guide can be quickly followed.


Question: Can you mount a transducer inside a kayak?

Answer: yes, you may! The kayaks are made from plastic, and so the transducer can fire the beam without much disruption through the plastic into the water.

Question: Where do you put the transducer on a kayak?

Answer: In your kayak, there are four methods of mounting a transducer – through the hull, the scupper opening, on the ruder’s rear, or a small pack with a suction cup transducer. Some may want to “clog” a regular transducer over your hand, so this cuts your equipment’s existence significantly.

Question: Does a transducer have to be in the water to work?

Answer: If the boat is not in the water, you cannot measure the capacity of the transducer to read depth.
