Things to Consider When Buying a Fish Finder

It’s a good idea to narrow down your options when searching for a fish finder. Here are some factors to consider.

Kayak’s Mounting Space

Before anything, you’ll need to closely think about the space you have available on your fishing kayak.

It’s vital to find a fish finder that permits you to set your device upon an apparatus. Your kayak’s gear tracks are often a good spot to mount a fish finder on. You may likewise mount it someplace on your kayak where you can easily view and access it.

Determining if you have enough room to accommodate your fish finder will also help you decide which format and screen size to purchase.

You might need to invest a couple of bucks into a bigger screen if you own a larger kayak, as it may be a bit difficult to read the information shown on a fish finder if you’re sat opposite the device. 

Portability

Fishing becomes simpler and more enjoyable when a kayak fish finder is portable.

A portable device permits you to check your data without having to worry about disconnecting it from a power source. When riding a kayak, especially, with all its restricted space, completing things in a snap is fundamental.

A lot of companies include nifty little features with their fish finders. Present-day innovation allows you to connect your fish finder with your smartphone, just like the Deeper PRO Portable Wireless Wi-Fi Fish Finder, or through a built-in Wi-Fi or Bluetooth connectivity.

There are likewise fish finders that permit you to explore the waters with the GPS of your handset.

The size of the unit is additionally what makes the fish finder portable. You may choose ultra-versatile units that are compact and some with sizes that can fit in your pocket, but everything relies upon which size is suitable for you. We recommend the more portable fish finders for inshore kayaks.

GPS

It’s recommended to search for a fish finder that has a built-in GPS system in the device. This feature won’t only help you track and locate fish much easier, but it’ll also encourage you to explore the waters without worries.

It also helps prevent getting lost while cruising over the water to locate your ideal fishing spots.

Some fish finders permit you to save your waypoints and fishing hotspots. They’ll even assist you with finding your way back to the main dock.

A fish discoverer with GPS would be a solid purchase. Yet, it may come at a higher price point compared to those units with preloaded maps only.

Battery

The longer your battery lasts, the better.

You certainly don’t need your finder to die while in the midst of fishing and miss a perfect catch!

Before buying a fish finder, make sure it’s powered by at least 12V of battery to ensure that you’ll have enough battery to keep your finder going.

Some fish finders are powered by motors instead of a removable battery, which are generally perfect for motorboats, but definitely not ideal for kayak fishing.

Depth

With today’s technology, you’ll find fish finder scanners reaching depths of over 1,000 ft.

This isn’t to say you specifically need to buy a device that reaches this depth. But we’d recommend you buy one that scans at least 250 ft to increase your chances of taking home a nice catch.

Resistance to Climate

Since you’ll be out in the water constantly, it’s important to know whether a fish finder is impervious to specific conditions. The climate could be extremely unpredictable and we wouldn’t want to end up with a faulty gadget after just a couple of uses.

It’s wise to invest in a heavy-duty fish finder that can withstand rough conditions, especially from water and residue, such as dust and pollen.

It’s a good idea to consider buying a protective case or gear for your kayak fish finder to protect the device from splashes of water.

Price

The total cost of a fish finder is commonly based upon the brand, features, and additional highlights installed in the device. 

This is why buyers need to know what essential features they need and what would be most advantageous when kayak fishing.

Fish finders come in a variety of prices. You’ll find some that cost $30, and others that cost $500. Fortunately, there are affordable fish finders that don’t compromise the overall quality of the device.

However, with the more expensive fish finders, they’re almost always much more durable than the low-priced once. This will eventually save you from paying more for replacements or repairs in the long run.

If you don’t mind paying a few extra dollars, it’ll be a good idea to invest in a fish finder with extra mileage, a better quality screen, built-in Wi-Fi, and a powerful quad-core processor that’ll deliver information without a second’s delay.

FAQ

Want to learn more about fish finders? Below is a common list of questions asked by customers looking to purchase, or already own, a fish finder.

What is the transducer?

A transducer is a system found in a fish finder that utilizes sonar innovation. This feature produces and conveys sound waves or signals that ricochet back to the fish finder.

It allows the fish finder to then assess and decipher the gathered information that’ll enable users to know where the fish are. Information also includes the state of everything that’s beneath the surface of the water like vegetation and sea-life, for example.

This framework aids you to look for the best fishing spots while maintaining a strategic distance from any expected dangers.

Are fish finders waterproof?

The transducer of a fish finder is waterproof. The fish finder itself, however, isn’t waterproof. Some models are water-resistant, but it’s not always true every single fish finder out there. They aren’t intended to work in full water submersion.

As you’ll be out in the water constantly as you go fishing, it’s advisable to consider purchasing a waterproof casing to secure your gadget.

What screen size is ideal for kayak fishing?

Any fishfinder with a screen size of more than 5 inches isn’t practical or advisable. It would be excessively burdensome for a kayak that has restricted space.

The perfect screen size for little kayaks is 3.5 to 4 inches, while 5 inches will do on bigger kayaks.

What scanning depth should a kayak fish finder have?

It’s best to buy a fish finder with a scanning depth of at least 250 ft – 500 ft if you’re only exploring and fishing in shallow waters. This measurement wouldn’t be sufficient, however, for deeper bodies of water.

The sweet spot is 500 ft for shallow and deep water, but that’s just our personal recommendation. Decide where you’d like to fish and choose accordingly. It all really depends upon personal choice.

Final Thoughts

The popularity of kayak fishing has steadily grown over the years. From the quiet solitude it brings to its increased access to the shoreline, many anglers are looking to try their hand in kayak fishing.

This experience is further amplified by the use of fish finders. With the aid of these devices and just a bit of skill, you’re sure to nail the perfect catch the next time you’re going kayak fishing.

If we had to choose, our favorite fish finder is undoubtedly the Garmin Striker 4.

The Garmin Striker 4 has everything you’re looking for in a fish finder, including some other features that aren’t found at the same price point. An example is its insane sensor that scans up to 1,600 ft and powerful high-frequency sonar.

This device isn’t waterproof, but to be fair, a lot of other higher-end fish finders aren’t, as well.

If you don’t mind paying a little extra, consider the Deeper PRO+ Smart Sonar Fish Finder. It has a ton of features that aren’t found in the aforementioned model.
