Key Considerations When Buying a Fish Finder

The different fish finder models available come with so many diverse features that it might become difficult to choose the right device. Knowing which features will make fishing more enjoyable for you is the key to finding the perfect fish finder device according to your purposes. Following are some features that you should keep in mind when looking at the various options:

Types of Fish Finders

There are a number of fish finders, and how you plan on using your device will determine the best fish finder for you. There are castable fish finders that can be attached to a fishing line. You can use these fish finders to scan spots that are hard to access without spooking the fish. Fixed fish finders can be installed on a boat while fish finders with GPS capability allow you to map your route and save your favorite fishing spot.


The operating frequency determines how wide or deep the sonar signal travels in the water. A low frequency like 83 kHz can scan a wide area, while a high-frequency signal like 200 kHz has the capability to transmit a more accurate and detailed image of what’s in the water directly below the transducer. If you plan on fishing both deep and shallow waters, you should pick a model that has multiple or dual operating frequencies.


The wattage of a fish finder determines how powerful it is and how fast will its signal travel through water. A device with a high wattage ensures greater power and will enable the signal to travel faster and deeper. If you prefer fishing in deep waters, you will need a fish finder with a high wattage like 4000 watts as it will be able to send signals to greater depths.

Beam Coverage

The sonar beam covers the area in a cone shape, which is why it is known as a cone angle. The cone angle refers to the width of the beam sent from the transducer. A large angle will provide a wider beam and help cover a larger area. A narrow beam, on the other hand, penetrates deep in the water. Choosing a device with dual-beam coverage will deliver the best of both cone angles.


Having a GPS-enabled fish finder is highly convenient. It not only allows you to map the coordinates of water bodies in your area but is also helpful in marking the spots with the highest fish densities. As a result, you can come back to the same spot again and again, without any difficulty.


A fish finder’s display is another vital consideration. Before choosing a kayak fish finder model, pay special attention to its screen size, contrast, color, and detail. Having a good-quality display will make it easier to discern the returning sonar signals.

You should also keep in mind the number of pixels a display has. A higher number of pixels will provide a smoother and clearer image. In addition, a color display makes it easier to decipher sonar signals under the bright rays of the sun. Moreover, a larger screen size enhances ease of reading. Ultimately, your decision depends on your budget, preference, and ease of use.

Portability (and Waterproofness)

Portable fish finders are becoming increasingly popular among anglers; however, fixed models provide more stability and consistency. Although portable models may seem like a good option, fixed fish finders can be used on both big and small boats.

It’s also important to remember that you’ll be using this device around water. It is bound to be rained on, splashed on, and even submerged accidentally. Therefore, you should pay particular attention to its construction and find out its waterproof rating, if any, before choosing a model.


Closing Thoughts About the Best Kayak Fish Finders

Due to recent advancements in technology and an increase in the popularity of fish finders, there has been a boom in the number of fish finder products available. If you want to spend more time fishing and less time cursing and waiting for a bite, then you should invest in a good-quality fish finder. Read the above reviews carefully before making a purchase as they will help you find a device that is best suited to your needs.
