What Should I Look For When Buying Fish Finders for Kayak  

Portable or Permanent Fish Finder

When selecting a fish finder for purchase, one must first determine whether a portable or permanent fish finder is right for them. While permanent fish finders tend to be more technologically advanced, they cannot be easily swapped from one kayak to the next, if the need should arise.

Screen Size

The larger a fish finder’s display screen, the simpler deciphering an image becomes. While small portable fish finders are highly versatile, they often feature scenes of much smaller dimensions, many of which can be difficult to read.

Screen Quality

The quality of the image that a fish finder presents is denoted in pixels. The higher a unit’s pixel count, the clearer its depiction of what lies beneath your kayak. Premium fish finders also feature a backlight, which allows their screens to be easily viewed in both lowlight and periods of direct sunlight.

Grayscale versus Colored Displays

Fish finder displays come in both grayscale and collared forms, while grayscale monitors tend to be far more economically priced, they are often more difficult to read. Colored displays, on the other hand, depict areas of contour in various colors, thereby allowing an angler to quickly discern between bottom type and variations in structure.

Glare from the sun

The midday sun can present issues for those attempting to monitor a fish finder. The glare created upon such a unit’s screen can be blinding, and create substantial difficulty for those attempting to quickly monitor water depth or structure. A number of premium fish finders feature backlights and screen brightness adjustments that can circumvent many of these issues. 


GPS equipped fish finders can be indispensable, as they allow anglers to easily mark waypoints, find their way to and from certain locations, and determine distances. This can be extremely important when attempting to fish in the most efficient manner possible.


A fish finder’s transducer is an essential part of the sonar system, which sends and receives signals. The transducer essentially sends out acoustic waves, which return back at varying speeds. Data related to the speed at which these waves return is used to calculate water depth.


The power rating of a fish finder is denoted by a particular unit’s RMS designation. This designation depicts the amount of power that is being driven through the system’s transducer. The higher this rating is, the easier it is for a fish finder to transmit a signal to deeper depths, especially in less than ideal water conditions.

Water Resistance

It is a given that any fish finder will be exposed to its fair share of water. However, not all fish finders are created equally when it comes to water resistance. When fishing from a kayak, choppy water can quickly drench your electronics, making it essential that a fish finder be highly resistant to water ingress.

Number of Frequencies

Many fish finders now have the ability to operate under multiple frequencies. This is of value due to the fact that a fish finder’s frequency determines its ability to operate efficiently in varying circumstances. The higher a fish finder’s frequency, the faster its detection speed. However, lower frequencies penetrate to deep depths.


Fish finders are available at virtually any price, from $50 to 5,000 dollars. A unit’s features and capabilities most often determine the point at which it is priced. Basic fish finders that offer little in the way of additional features fall toward the lower end of the price spectrum. While highly-advanced, GPS-equipped units bring a premium.

Matching the Fish Finder with Your Fishing Style

Structure Fishing

When structure fishing, or covering large expanses of water, the use of a GPS-equipped fish finder can be of immense importance. Sonar units of this nature offer high-definition depictions of what lies below an angler’s kayak at all times. This makes it possible to know when and where to cast in the bulk of situations.

Most top-tier fish finders also come equipped with a host of GPS capabilities. As such, anglers can store waypoints, judge distances, and navigate as they please. This increases an angler’s efficiency while they are on the water, and assists one in catching a greater number of fish.

Shallow Fishing

When fishing in the shallows, close to your launch location, one will need little more than a basic fish finder combo. In this situation, there is little reason for GPS use, or the use of additional mapping features, which tends to tack additional costs onto the total purchase price of a new fish finder. 

In many cases, a basic fish finder can be purchased for approximately $100, with higher-end models being priced in the $200-$300 range. A unit of this nature is perfect for the avid weekend angler.

Questions & Answers

How deep do you fish?

When fishing from a kayak, the depth at which you fish is directly determined by the species of fish that you are fishing for. While panfish, such as bluegill, crappie, and redear sunfish can often be found in water as shallow as 5 feet, species such as catfish are notorious for residing at depths of 20 feet or deeper. Therefore, your fishing strategy should reflect the seasonal patterns of the type of fish that you are pursuing.

How far do you travel?

Kayak anglers travel a wide range of distances to reach points of interest. The exact distance which is traveled on a given day is often determined by launch access, or a lack thereof. If an angler is able to launch their kayak in close proximity to the location they intend to fish, travel can be minimized. On the other hand, difficult to reach areas can necessitate travel of up to a mile or more.

How much room do you have?

While many newer kayaks tend to be far more spacious than those from days gone by, there are still many space-related constraints facing kayak anglers. As a result, an ever-increasing number of those fishing from a kayak has begun utilizing handheld fish finders, as opposed to permanent fish finders, which can be more difficult to mount with space at a minimum.

How will you connect the transducer to your kayak?

There are several ways that a transducer can be mounted to a kayak. One can mount their transducer in the hull of their boat, secure it to pre-fixed mounting recesses found on the underside of some kayaks, or hang their transduce over the side of the kayak with any number of specialty mounting products.

What is your power source?

Standard fish finders have been traditionally powered by deep cycle batteries, in much the same way as a trolling motor. However, more recently, small portable fish finders have drawn their power from small rechargeable or disposable battery packs.

How Much Mounting Space?

It is often difficult to find enough surface area to mount a fish finder display within a kayak. However, numerous kayak specific fish finder mounts have been released over the past several years, which come in both universal and model specific forms. These mounts make it possible to affix a fish finder display to a kayak in many different ways.

Is A Fish Finder Worth It On A Kayak?

For serious kayak anglers, a fish finder comes as a worthy purchase. A fish finder allows you to make more efficient use of your time on the water, which typically equates to a better overall catch. GPS equipped fish finders can also be of significant value when attempting to navigate unfamiliar waters. However, in the case of a casual weekend angler, whether or not to use a fish finder often comes as a matter of personal preference.
