Good Inexpensive Fish Finders for Kayaks [2022 Update]

Fish finders are devices that help you find fish. The data shown on the display is quite accurate. It uses GPS to track the exact location of the fish. There is a misconception about fish finders being over expensive. While some fish finders are expensive but, there are tons of good inexpensive fish finders for kayaks. There are somethings that you must consider before purchasing a fish finder.

5 Things to Consider Before Buying Fish Finder:

1. Display

Most of the fish finders have a colored LCD. While it may not be that big, but it does the work. As we are discussing fish finders for kayak, we don't even need a big screen.

But you need a bright display that shows accurate colors. 

2. GPS

GPS is the most important feature of a fish finder in my opinion. Most cheap fish finders normally lack a good GPS. That's why you need to make sure the data shown in the GPS is accurate.

3. Transducer Type

The transducer sends out a sonar signal to find fishes. This feature allows the fish finder to mount at the kayak. Upgraded fish finders can also come with angled cones to send signals in various directions. 

4. Signal Frequency

Most modern fish finders allow several frequencies to work with. Even if the frequency is as low as 50 kHz. The variety in frequencies will help you to send signals in various directions.

5. Accuracy

Accuracy is the most important part of a fish finder. If the fish finder isn't accurate what is the point of buying it? That's you must see reviews about the product you are going to buy.

2 Best Fish Finder in the Market:

1. Garmin Striker 4 GPS Fish Finder for Kayaks - Best Fish Finder GPS Combo

For 100$ the Garmin Striker 4 GPS did a lot of things right. The GPS tracker is quite accurate. The interface is simple and easy to use. A beginner-friendly interface is always welcomed. There are 3 different models available in 3 different sizes. 3.5, 5, and 7 inches.

The fish finder is water-resistant and has an IPX7 rating. It's a great device for freshwater and saltwater usage. 1600 feet in freshwater and 750 feet in saltwater.


  • Easy to install.
  • Waypoint map.
  • Clearvü scanning sonar.
  • Easy to operate keypad.


  • The screen is not waterproof.
  • In shallow water, the accuracy is lower.

2. Deeper Pro Fish Finder for Kayaks with Smart Sonar- A Great Fish Finder for Canoe

If you can increase the budget and have no problem spending around 200$ on a fish finder. Then the Deeper Pro fishfinder may intrigue you. The feature that I liked the most about this fish finder is the connectivity.

You don't need to keep your cellular data on to sync it between the phone and the fish finder. The fish finder acts as a hotspot and connects with the phone seamlessly. This fish finder is best suitable for shore fishing.

The Deeper Pro app is available for both android and IOS. This is a versatile and wireless fish finder. The accuracy is quite good. But like I said earlier, it's best for shore fishing.


  • Unique versatility.
  • Wireless.
  • Lightweight.
  • App support.


  • Pricey.
  • Not a great battery life.

I mean with that much feature the battery life is low. That's why you need to make sure you are okay with lower batter life. Or just carry a power bank to charge it on the go. If you want the absolute best then you can't hope to get that for below 100$.

We did say you can find good products. Both of the listed fish finders is good products. But not the absolute best by any means. There are better fish finders out there but they will drain your wallet.
