What is a Fish Finder?

Fish finder is an instrument used to locate fish underwater using sonar technology. They run beneath the water to map shapes and identify objects that are found underwater like fish and rocks. The technology of these devices then creates a picture on the display screen of everything it finds. These cameras use sonar technology to identify objects and then translate the picture using a visual representation. The sonar puts out signals and when the signal hits an object it bounces back to the fish finder.

Best fish finder for kayak

Most fish finders are portable; however, they require mounting to your kayak or boat. They are also waterproof, so if you happen to get water on it, you will not damage the delicate electronics inside. It used to be that all fishfinder GPS units were black and white, however today you will find some color units. Despite that, almost all units will include a sonar, which is what is needed to spot the fish.

Fish finders are not as costly as the other navigational equipment. The price range is anything between $99.00 to $899, depending on what brand you pick. Though fish finders may not always be perfect each and every time, their range and accuracy level will most likely reduce your fishing time by about 50%. So picking the best fish finder for kayak that suits your style will save you a great deal of time and effort.

Before I get to some of the best depth finder for kayaks in the market, briefly, I’ll go through some of the factors to consider when getting this device for fishing on your Kayak.

Buyer’s Guide – Best Kayak Fish Finder


A Fish finder power is measured in Wattage. The greater the Wattage, the faster your fish finder displays the readings. A high level of power can also go deeper.


The higher the frequency, the more detail you get to see on screen. Fishfinders with high frequencies work best in shallow water, whereas those with low frequency are more productive in deep water.

Screen resolution

This refers to the number of pixels the screen displays. The higher the number of pixels, the clearer the view as displayed on the screen. A higher screen resolution enables the angler to get a better idea of the objects in the water. It will make it easier to distinguish fish from other objects.

Screen size

This, of course, goes hand in hand with the screen resolution. Having a large screen size increases the level of detail you would like on your display. In other words, with bigger screen size, you get to enjoy an HD display.

Color or black and white screen

Color screens are much better. They are more enjoyable to look at with beautiful images illustrating various objects in the water. Needless to say, they are more detailed compared to their black and white counterparts.

However, it does depend on the budget. Color screens are a bit expensive, hence you can go with black and white if you do not have enough cash for a color screen. They are relatively accurate, though.

Fixed vs portable fish finders

A fixed fish finder is much more suitable for a boat that you own. A portable is handy if you have rented the vessel. It takes up less space and is a bit more expensive. However, it is a small price to pay for the convenience brought by a portable fish finder.

GPS enabled

It is advisable to purchase a fish finder with a working GPS. This is very useful especially if you are exploring areas that you are not familiar with. In case you get lost, a good GPS system makes the difference. A canoe fish finder with no GPS works as well if the angler has prior knowledge of the river, sea or lake and its contours.

Frequently Asked Questions (FAQ)

What does a fish finder do?

A fish finder helps to locate fish underwater using sonar technology. A frequency is transmitted and when it strikes something such as a fish, it is reflected back and display information like the size, composition, and shape of the object.

What’s the Best portable fish finder?

Garmin STRIKER 4 Portable. It’s lowly priced, light, has an integrated GPS, great display screen, in-built flashers and can be upgraded to CHIRP technology for better images.

What is a Chirp Sonar?

CHIRP is an acronym for Compressed High-Intensity Radiated Pulse and unlike standard sonar sends continuous sweep of frequencies ranging from low to high, then interprets the returning frequencies individually to provide a much wider range of information, clearer, and high-resolution images.

What is Chirp Sonar

Which CHIRP frequencies should I use?

Chirp uses 3 frequencies:

  • High CHIRP (150-240 kHz) which is best for depths less than 600′ for inland and freshwater to identify game fish near the bottom structure. It provides more refined details for small objects.
  • Medium CHIRP (80-160kHz). It is also best for depths less than 600′ and displays a wider coverage area, showing larger fish arches but provides less detail than high CHIRP for smaller objects.
  • Low CHIRP (below 80 kHz) is used for deep waters with amazing depth performance of up to 10,000′ and marks targets at all depths in the water column

What is a Chartplotter fish finder?

A chart plotter fish finder is a unit with inbuilt chart plotting and fish finding functions. The chartplotter integrates GPS data with the capability to display electronic charts/maps.
