Factors You Should Consider When Selecting a Fish Finder

Knowing the most recommended fish finders by the experts allows you to narrow down your choices to the best options. Yet, if you really want to get your selection right the first time, it will help if you are cognizant of the following essential factors to consider when selecting a fish finder: 

Display Screen Size

The screen display size is crucial in choosing a fish finder, and if you want to select right the first time, it will be best to consider this factor. With a larger display screen, you can view the images better without hurting your eyesight. Besides, it should also have an adjustable backlight to let you adjust the display’s brightness based on the prevailing conditions and the sun’s angle. Thus, if you would fish during dawn or dusk, you can quickly conveniently set up the display’s brightness. 

On the other hand, if you fish during the daytime, you will need something brighter. So, you will need a backlit screen that enables you to see the screen data even if the sun is directly shining on your fish finder display. 

One downside of having a fish finder with a larger screen is that if you got cramped space in your kayak, your fish finder might take enough space in your kayak. A fish finder with a smaller screen would be more suited for your use in such a case.

Screen Navigation

Another essential factor to consider is the screen navigation provided by a fish finder. Most screen navigations nowadays come with a touchscreen feature. And you might prefer a fish finder that offers a touchscreen feature. Yet not all kayakers would like to use touchscreen navigation. 

One alternative to touchscreen navigation is push-button navigation, which is more commonly used in GPS and cell phones. A few kayakers love this navigation method, allowing them to navigate while their fingers are wet. 

If your fingers are slimy and dirty, you would surely not want to do touchscreen navigation because you might dirty the screen. It will be a hassle if the screen you use to find fish gets defiled by your fingers. So, if you think the touchscreen navigation system isn’t best for you, it will be best to go for the alternative push-button navigation system.


Another salient factor to consider is the range of frequencies of your fish finder. Any fish finder will use a specific frequency range to find fish and map the water floors. So, it is crucial to determine beforehand the frequencies utilized by a fish finder before shelling out your hard-earned money for one. 

Most fish finders use ultrasound frequencies ranging from 15 kHz to 200 kHz, though most recreational fish finders carry a frequency range from 50 to 200 kHz. However, fish finders designed for professional or commercial usage may use frequencies like 15, 22, 28, 38, etc. Besides, you will find special fish finders that use 400 kHz, though such fish finder is very rare. 

It will be good to note that the searchable range and depth usually depend on the fish finder’s frequency. If you want a detailed search, you should go for a fish finder that has a high frequency. Yet, such a frequency is not usable for deep water search. Low-frequency ultrasound, however, is best for general searches on a broader area.

Mounting Feature

When kayaking, you will need to mount the fish finder anywhere in your kayak to let you focus on balancing and navigating the waters. So, when selecting a fish finder, it will be best to choose something easily mountable to your kayak. It should also have that mounting compatibility with your kayak to allow you to use it while kayaking freely. 

Some fish finders come with a design that lets you mount them permanently onto your kayak’s bow, stern, or gunwales. Other fish finders feature a design that allows you to troll them behind or float them near your kayak. You can also find handheld units that you can mount in the cockpit or hang around the neck when not monitoring or mapping. 

The thing is, when choosing a fish finder, it will be best to select something that offers various options for trolling, mounting, or floating it. You can determine the suitable one for your use if you are regularly fishing. Besides, the different mounting ways would come with their pros and cons.


Another critical factor to consider is the fish finder’s power output. Fish finder power gets usually measured in watts. So, the readings get quickly displayed when using a fish finder with higher wattage. On the other hand, if you got a fish finder with less wattage, you could expect a slower in the transmission of data and sonar waves. With less overall power, your fish finder will get weaker sonar waves and provide less precise readings. 

Remember that you can gain clearer and more detailed readings with higher wattage. You can use a less powerful fish finder when navigating shallower waters. But once you go into the deep, it will be best to use a more powerful fish finder. 

For every 100 watts, at 200 kHz, your fish finder can provide readings up to 400-foot deep. Most mid-range fish finders offer dual frequencies. With this fish finder, you can view, on a split-screen, the readings of both frequencies.

Battery Life

Another crucial factor to consider is the power source of your fish finder. The obvious thing is that you will not have access to a power outlet when kayaking. So, you need to get your fish finder’s power from other sources. 

Most fish finders are battery-powered. These batteries are standard marine batteries, but you need to ensure that the battery you will use comes with a cover or waterproof box. 

You can also buy a fish finder with built-in waterproof battery packs. Always remember that the batteries should be long-lasting to enable you to use your fish finder for a more extended period.


Many beginners in fishing learn fishing while kayaking by trial and error. This is pretty understandable because you need to learn two skills if you want to fish while kayaking. Besides, many fishers and anglers still rely on their intuition when locating their target fish. But if you want to do it right the first time, it will be best to utilize innovative technologies like the fish finder. 

If you’re a beginner in fishing, you don’t need to learn fishing the hard way. You can always maximize modern technology and employ hi-tech fish finders while fishing. In this way, you will no longer rely on guesswork or hunchs in finding your target fish.
