What Should I Look For When Buying Fish Finders for Kayak?
Portable or Permanent Fish Finder
When selecting the best fish finder for kayak to purchase, one must first determine whether a portable or permanent fish finder is right for them. While a permanent fish finder tends to be more technologically advanced, it 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 a small portable fish finder for kayak is highly versatile, it often features scenes of much smaller dimensions, many of which can be difficult to read.
Screen Quality
The quality of the image that a kayak 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
The best fish finder for kayak 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
A GPS-equipped kayak fish finder can be indispensable, as it allows 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.
Transducers
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.
Power
The power rating of a kayak 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 kayak 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.
Price
Fish finders are available at virtually any price, from $50 to 5,000 dollars. The best kayak fish finder 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 kayak 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

Is a fish finder worth it on a kayak?
For serious kayak anglers, a fish finder comes as a worthy purchase. The best fish finder for kayak allows you to make more efficient use of your time on the water, which typically equates to a better overall catch. A GPS-equipped kayak fish finder 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.

How will you connect the transducer to your kayak?
There are several ways that a fish finder for kayak can be mounted. For example, 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 transducer over the side of the kayak with any number of specialty mounting products.

How much mounting space?
It is often difficult to find enough surface area to mount a fish finder display within a kayak. However, numerous fish finders for kayaks mounts have been released over the past several years, in both universal and model-specific forms. These mounts make it possible to affix the best kayak fish finder display in many different ways.

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.

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, small portable fish finders for kayaks have recently drawn their power from small rechargeable or disposable battery packs.

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 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.
