What is a fish finder and why do you need one?

Some anglers might think that getting kayak fish finders are not necessary and could just be an added cost. However, that is a misconception. First, not all fish finders are costly. You don’t need to spend hundreds of dollars just to get a fish finder. There are a lot of inexpensive electronics out there you can use. Also, these basic fish finders have benefits you might need in your fishing – benefits that outweigh their costs.

So, what is the best fish finder and why do you need one for kayak fishing? These are just some of the reasons:

In locating bait

Sometimes, you might find it difficult to locate your bait once it is on the surface. During the times when baits are suspended in the water column, the sounder on your fish finder can locate them. You won’t regret purchasing a fish finder in times when you can’t place your bait on a dependable spot.

Finding structures or flat areas

When you want to catch a particular fish species, you would want to use your electronics. Finding the structure or the flat areas will help you identify the depth of the bottom, which is at your advantage when you are in an unfamiliar area where you do not usually fish and are not used to the fishing spots. With this, you would be avoiding guesswork and would have a more systematic way of fishing.

Great when diving off the kayak

Some want to dive off their kayak for recreation. However, they have to make sure first the depth of the water to avoid hitting any reef structure at the bottom. To save time, fish finders could predict the depth and you could identify if a particular area is a safe spot to dive into.

Aside from all these, a fish finder has several features that are very useful as well like the transducers, dual-screen options, and the like.

What makes a good fish finder?

Now that you know the importance of a fish finder, you need to know how to find the right one for your needs. There are several factors that you need to consider, and we listed all of them for you.

Power

Seeing the reading on display of your fish finder is one important thing that you need when you go out fishing. This can be achieved best only when your fish finder has great power. Fish finders with high wattage display readings faster compared to those with low wattage.

Fish finders with low wattage would display slowly and work best when you are fishing in shallow water.

Screen Resolution

Pixels are used when measuring screen resolution. Greater pixels on your screen would mean greater screen resolution. Through this, you can see more details on the screen. Aside from the screen resolution, you also want to consider the screen size for a clearer display. Screen resolutions that are no less than 240 x 160 pixels work best. But you can also go higher and pick those screen resolutions that have a maximum of 640 x 640 pixels.

Transducers

Another important part of a fish finder is transducers. They emit sonar waves and sonar signals to the water. Usually, you need to install the transducers to your fish finder as they are sometimes out of the box. However, you can easily mount it to your electronics. You would want to consider that cone angle. A wider cone angle means more area coverage.

If you are an angler who uses in-hull or thru-hull transducers, it would be great if you choose that which has plastic housing for hulls made of metal or fiberglass. For hulls made of aluminum and steel, however, it would be best to use transducers with stainless steel housing. Bronze housing is more appropriate for wood hulls.

Cone Angle

As mentioned, wider cone angles could give you more coverage. Transducer cones have angles that range from 9 to 60 degrees. If you prefer to fishing in different water depths, then choosing a 20-degree cone would be best for you. While wider angles give you wider coverage, the widening of the angle also means lessened sensitivity when you fish in deep waters, so you need to choose carefully.

Frequency

Kayak fish finders may have dual, single, or multiple frequencies. For dual-frequency transducers, 20 and 30-degree cones are available. A lot of transducers may come with around 50 up to 200 kHz. Fishing on shallow water means needing higher frequencies like 192 or 200 kHz. Deepwater fishing requires kayak fish finders of lower frequency.

Mounting Space

In buying your kayak fish finder, you of course want to examine your kayak. Is there enough space on which you can place your fish finder? Your kayak must have space that is enough to hold cable rods and accommodate a fish finder of sufficient screen size that would allow you to see details. For larger kayaks, you might want to choose fish finders with a 5-inch screen. There are also smaller screen sizes, around 3.5-4 inches for kayaks of small sizes.
