Best Fish Finder for Kayak Adventures 

Why Is the Best Fish Finder for kayak Adventures Necessary?

The odds are you won't fish anything or you won't be able to locate where exactly the school of fish is if you make guess.That is why you need a fish finder. With technology, you can fish efficiently and you don't need to wait all day long to find that favorite fishing spot of yours.

With fish finders that are best designed for kayaks, you get to see the structure underwater and locate where the fishes are. You get to analyze the contour, the water conditions, temperature and several other details. 

Things to Consider When You Invest In the Best Fish Finder for kayak Adventures

Well, it took me years before I decided to invest in the best fish finder for kayak adventures. I was confused if fish finders worked as great as it's expected to. I did not know what design or specifications I need to choose from and the availability of different models of fish finders got me confused. I started doing my own research, sought advice from several anglers and tested a lot of fish finders for myself. Here are few things you need to keep in mind when you decide to get a fish finder for your kayak.

Display of the Best Fish Finder for Kayak Adventures

Kayak fishing is way different than fishing in small boats. You've very less space to accommodate and you need to consider the loading capacity as well. The display or the console is what gives you the visualization of what's happening underwater. It's basically the most important unit. 

While large displays are good as they visualize over a large portion of water, anything larger than 5-6 inches would make it difficult to mount it. Plus, they are heavy too. As kayaks are not so wide, I prefer display sizes that are less than 5 inches. I generally go with the 4-inch models.

Another display feature you need to consider in buying a perfect fish finder is the screen resolution. The better and clear picture you get, the easy it gets to differentiate echoes, and other parameters.Screen resolutions lesser than 240 X 160 pixels are what I'd completely avoid because the display is unclear. Though they are cheap, it gets really difficult to analyze the parameters. I generally prefer the highest resolution fish finders that have 640 X 480 pixels.

Fish finders also come in color and black and white models. If you are tight on budget, the grayscale display models are fine but with a color display, the viewing becomes easier even under bright light. 

Power and Batteries of the Best Fish Finder for Kayak Adventures

You'll have to setup the power source all by yourself. You pack the marine battery in a waterproof box and power the transducer and display. To avoid the hassle, get a portable fish finder as it comes in a package that is ready to mount already. 

If you plan to go with a regular power source, wattage is what you need to consider. The better the wattage, the better the overall performance. High wattage power sources will make the overall process faster and effective in displaying and reading. 

100-watt batteries are cheap, but they are suited only for shallow water fishing. I generally prefer to go with the 600-watt source because it's light and works really well. 

If you are a serious angler, you better go with the 1000-watt batteries. ​

I also look for power sources that accommodate replaceable batteries. I prefer taking an additional battery in case the first one runs out of power. 

Transducers of the Best Fish Finder for Kayak Adventures

The transducer is the backbone of the fish finder. It sends sound waves to locate the terrain inside water. 

Basically, it operates in the sonar principle where the sound waves are generated and passed inside water. These waves reflect back and a picture is developed which is then displayed on the screen.

More the frequency of the transducer better is the display. Fishfinders come in different frequencies: 50, 83, 192 and 200 kHz. There are also expensive models that come with dual or multiple frequencies and you get to see the 3D images on the display with them. 

Cone angle is also an important feature of the transducer in fish finders. With a bigger degree of the cone, the perspective of the underwater layout increases. It covers a significant portion of the water just below the surface. However, unlike narrow cones, these can not penetrate deep into the water and find the composition of the bottom.

Portable or fixed?

Portable fish finders are easy to use. They are entirely self-contained and are the better choice considering their easiness to use. 

They have already designed battery power supplies and come with a carrying case. It also has a transducer that is already attached to the transom. If you ice fish or “fly-in” fish, they are perfect because they are comparatively small and as the name suggests they are portable. 

Fixed fish finders are still the most used models by several kayakers. They are large but less expensive and generally come with additional features of chartplotters, map and backtrack GPS.
