How to Choose the Right Kayak Fish Finder


You need a fish finder that works well when you’re out on the water. You should be able to read the screen easily. You should consider the amount of wattage the fish finder uses to decide. Fishfinders with low wattage power don’t put out easy to read information and can become a burden. When you’re out in a kayak, and you don’t know the depth, the readings can be slow. It’s ideal if you’re in shallow water, but doesn’t do you any good when you’re in the middle of open water. Typically, a fish locator should run faster to keep up with the water.

Screen Resolution

If you get a fish finder with a display that’s difficult to read, it won’t help you. The screen resolution is measured in pixels. Just like your TV at home, the more pixels it displays, the better the display quality. The screen resolution and size of the screen will determine if the fish finder is right for you. If you’re looking for the right fish finder for kayak fishing, there are screen resolutions with 640 x 640 pixels. The least you should consider is 240 x 160 pixels. It makes a huge difference when you can tell the difference between a rock and a fish.


The transducer is important parts of a fish finder. It emits sonar waves into the water. The sonar signals bounce off objects in the water and come back to the transducer. There are different types of transducers available, with some of them better than others. For a kayak, you want a transducer that is easy to install inside the kayak. If your kayak is fiberglass, the fish finder would be a bronze transducer. It will fit perfectly in the kayak, and give you the correct readings.

Cone Angle

Along with the transducer, the cone angle is important to finding the best kayak fish finder on the market. The cone angles typically come in varying degrees, from 9-60 degrees. 20-degree cones are ideal for fishing in all depths of water, allowing you to change from depth to depth quickly. One thing to keep in mind is that the higher degree of the finder, the more area it covers. While this is ideal for fishing in large water bodies, the sensitivity will go down the higher the angle. You should consider where you’re going to fish the most, and prepare the best you can.


The frequency of the fish finder allows you to tune into the depths under the surface. They operate in dual, single, or multiple frequencies, and they all have their benefits. Fishfinders come in frequencies of 50, 83, 192, and 200 kHz. When you’re trying to find the portable fish finder, you want to consider where you’re fishing. Higher frequencies are ideal for shallow waters, while deeper depths operate better on lower frequencies. You can map out where you’re going to fish and get an idea of how the deep the water is before you decide which to get.

Advantages of the Kayak Fish Finder

Determine Fish Location

Under the surface of the water, fish have plenty of hiding spaces. When you can locate where the fish are hiding, you can zero in on their location. It’s an easier way to find fish than keep your line out in the water.

Determine the depth of the Water

One problem with fishing without a fish finder is that you don’t know how far down the water goes. Fish can be near the top or the bottom, but you don’t know the difference when you don’t have a fish finder. Determining the depth will give you an idea of what you’ll find in the water.

Get the Temperature of the Water

Knowing the temperature of the water is good for any fisherman. You can find out where the hot and cold zones are, which helps you locate fish. There are certain species of fish that prefer colder temperatures to hot, and vice versa. Knowing the water temperature allows you to locate what you want to catch.

They’re not too Expensive

While the misconception is that fish finders are expensive, this isn’t such the case. You can find some of the fish finders under $200, but there are some that cost thousands. Determining how you’re going to use the fish finder will go a long way to find the right fish finder for you.

What is a Good Price for a Kayak Fish Finder on the Market?

Determining what features, you want, and how powerful you want it, a fish finder can be expensive. It doesn’t have to be that way, though, as you can find the fish finder for a good price. If you’re looking for a good price for a good fish finder, you can expect to spend between $200 and $500. Things like the display, transducer, and cone angle can all add up. You won’t have to spend the thousands of dollars for a fish finder, but you should consider what features you need. They won’t break the bank, but you should consider what quality you want, and determine the price.

Final Verdict

Fish finders are ideal for any fishing lover, and they can help tremendously. They allow you to place your favorite fishing spots down on the map so that you can come back later. Fishing without a fish finder is doing a disservice to yourself. If you want to stay in the game and get the biggest fish you can find you need a fish finder. They are inexpensive and provide crucial information about your fishing spots.

If you’re looking for the best kayak fish finder, the Deeper Smart Portable 3.0 is highly recommended. It does everything you want a fish finder to do and includes a rechargeable battery. You can sync it up with your smartphone or table to get the information directly to your hands.
