Why You Need a Kayak Fish Finder

A kayak fish finder is a gadget that has only become popular in recent years. What was originally thought to be an unnecessary piece of equipment has proven to be one of the most important factors in fishing success in a kayak.

Because the small and light water crafts are so versatile, as a fisherman it’s nearly impossible to know the depth, the bottom structure of where you’re paddling at any given time.

It’s also challenging to determine at what depth you’ll find fish, and how big they are, making it difficult to choose appropriate bait and lures.

It’s also important to have a fish finder if you want to plot routes to regular fishing holes, or you plan to travel outside of familiar areas and may need GPS to help you get back home. On a windy or choppy day, you could get blown off course, but the technology will keep you from getting lost.

Kayak fish finders come in a variety of sizes, prices, and installation options. Each one has their pros and cons, but they all will make it easier to catch fish when you’re out on the water.

A fish finder is the one guaranteed way to know where to find your catch of the day.

The Importance of Using a Good Kayak Fish Finder

Some people make do by using an app on their cell phone that offers some similar features to a good kayak fish finder.

While you will have some of the benefits, we recommend not using this option. Every time you take out your phone you risk it getting wet or falling overboard into the water.

Additionally, while you can find data on the depth and currents online, no app will be able to get you a reliable reading on where and how large the fish in your vicinity are.

You will want to choose a fish finder that is waterproof, mounted to your vessel for easy visibility, and that provides an accurate reading in any conditions.

Elements of Kayak Fish Finders

When choosing the best kayak fish finder, you want to get one with all of the features that are most important to you. There are many different models in the market, and there are several different types and brands that can work for your kayak.

The fish finder you choose will depend on what types of conditions and fishing you plan to use it for, as well as the budget that you have to spend.

Here are some of the most common options you have in the best kayak fish finders. Many models will have some version of these attributes as part of their design.

  • Display

Being able to see the readings from your sonar on your fish finder display is crucial. You’ll want to look for one with a screen size that is easily visible for you. There are many different display options available, so remember that a higher resolution will display data more clearly and in more detail.

  • Power

Choose a model with an appropriate level of power and a source that makes sense for you. Some are battery operated, while others need to be plugged in and charged before they’re mounted on your vessel. A higher wattage typically means the fish finder can display its findings on the screen faster.

  • Sonar

There are two main types of sonar in the best kayak fish finders, down scan and side scan sonar.

Down scan sonar broadcasts a signal directly downward from your vessel. Because it is a focused signal, it can give you greater detail like showing the individual number of fish in a school at greater depths than a side scan sonar.

However, in shallow water, you might experience a glare with down scan technology, and it limits your ability to see what’s going on in the peripheral of your kayak.

Side scan sonar broadcasts out in a fan-like arc to give you a better picture of your entire surroundings. This technology will typically give you an accurate picture of 75 to 100 feet on all sides of your kayak. One major downside is that it does not provide clear data in deep water at 75 feet or more.

  • Transducer

The component of the fish finder that goes in the water and transmits that sonar waves that locate objects, fish, and the bottom. Most models will come with a transom mount transducer which is easy to install and use.

  • GPS

Some units will come equipped with GPS, and some of the high-end models will have more advanced features including charting and route plotting options.

  • Waterproof

Believe it or not, not every kayak fish finder is waterproof. As a piece of technology on a small watercraft, there is a very high likelihood it will get wet from time to time so you’ll want to look for a model that can stand up to regular use.

Which Fish Finder Is Right for You?

Determining which fish finder is the best choice boils down to three main factors. You’ll want to choose one that can accommodate the depth of the body of water you plan to fish in, that is an appropriate size and has a quality display that’s easily visible on your craft, and that fits in your budget.

You’ll also want to determine what type of mount you’re most comfortable with, whether it’s a drill-down, suction cup, track base or clamp, and choose a model that allows for that method.

Selecting your fish finder is a personal decision, but there’s no doubt that it will be a good one. For more proof, check out this video below of what a day fishing on the water can look like with technology on your side.
