The Best Kayak Fish Finder – Review 2021

Have you ever found yourself in a situation where you spent the larger part of your morning fishing with absolutely no luck? Let us be honest, we all have been there. We all have gone through the utter annoyance of cast after cast with no bites. Even the most efficient rod, personal flotation device (PFD), and kayak cannot assist you in these frustrating situations. Therefore, to make sure that your fishing excursion is an absolute success, you need to have an operational kayak fish finder because even with the required proficiency there is no way to get lucky with fishing.

Kayaking has become one of the most ideal nature-oriented activities in the contemporary world. Whether it involves spending your day at an exquisite lake or a rogue river, kayaking gives you the ultimate exhilarating experience of nature. Like every other outdoor activity, kayaking also involves some rudimentary equipment such as a kayak, paddle, and fishfinder. Once you have your fishing kayak, it is time to start looking for a kayak fish finder that precisely suits your unique fishing style and environment. 

An efficient kayak fish finder does away with inaccurate casting in the water. There are a wide variety of fish finders available in the market to meet the needs of kayak anglers. To help you find the best model, we have reviewed some of the best kayak fish finders to make your kayaking experience a breeze. 

Things to consider before buying the Kayak Fish Finder 

1) Power

A Kayak Fish Finder’s power is measured in Watts. The more the wattage, the swifter the finder will exhibit the required readings. A high-level power can potentially also go to deeper lengths. 

2) Frequency

High-frequency models deliver more details than low-frequency models. A fish finder with a high frequency works best in shallow water while the one with low frequency is more efficient in deep water.

3) Screen Resolution

Screen resolution refers to the number of pixels displayed on the screen. A higher screen resolution is always the best and makes it easier for the angler to detect fish from other sea creatures. If you are looking for deep-water fish then you need a down-imaging sonar to get a better view with great clarity. On the contrary, if you are after bass or bluegills in the shallow waters, then a side imaging device is advisably the better option. 

4) Screen Size

Bigger screen size is always a plus, however, if your fish finder gives a better quality picture with its small size, then it would be adequate for you.

5) Portable vs Fixed Fish Finders

A portable kayak fish finder is always suitable and comes handy if you have rented the vessel. It consumes less space but it is a little heavy on the pocket. Buy one with a float-style transducer that delivers a read-out signal directly to your cell phone. On the other hand, a fixed fish finder is more appropriate for you if you own the kayak/boat. 

6) GPS enabled

In case you are exploring the waters that you are not familiar with then you need to buy a kayak fish finder with an in-built functional GPS.

Kayak Fish Finder- Frequently Asked Questions (FAQs)

1) Can you mount the transducer inside the kayak?

People usually mount the transducer on the hull of the kayak i.e. the outside. The transducer only functions when it touches the water.

2) How do you connect the transducer to your kayak?

You can fix the transducer to your kayak in various ways to facilitate your catch:

  • Some of the transducers can be attached to the trolling motor.
  • While some of them must be mounted directly to the bottom of the transom.
  • Various recent kayaks feature scupper holes, which permit you to pass the transducer through the hull for easy and seamless mounting. However, old kayaks seldomly have these features so you need to buy a depth finder that can efficiently work with your kayak.

3) What is a Chirp Sonar?

CHIRP is an acronym for Compressed High-Intensity Radiated Pulse and contrary to other standard sonar sends a continuous sweep of frequencies from low to high, this infers the returning frequencies separately to deliver a much vast range of information and images with immaculate clarity. 

4) Which CHIRP frequencies are suitable for a kayak fish finder?

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.

5) What is a Chartplotter fishfinder?

A chart plotter kayak fish finder is a device with an inbuilt chart plotting and fish locating operations. The Chartplotter integrates the GPS data with the capability to display electronic charts/maps.
