Tips for Choosing the Best Fish Finder for Kayaks
There’s a huge range of different models available out there. Some come with high-end features, while other some nominal features to facilitate average-to-medium needs. It’s up to you what type of fish finder you need. One can easily be overwhelmed by a big competition out there. However, with the right knowledge, you can easily pick the right model matching your requirements.
Before you start looking for a fish finder, be sure to define the location where you intend to fish. Some areas are challenging for fishing and some are easy. First off, analyze your fishing spot carefully, considering everything involved. This will help you a lot in choosing the right fish finder.
Here’s a list of what you should look for in a fish finder:
Transducer
The transducer is a part used to transmit sound waves and provide you with a picture of what is underneath the surface of the water. Quite similar to a radio antenna, a transducer sends out a sound wave and captures the returning echoes. Some features that are crucial in a transducer include but are not limited to installation type, cone angle, and operating frequency. It can be mounted in multiple locations, so it can sit where it’s more convenient for you. It is usually fixed on a trolling motor or a transom, or even in the smaller watercraft.
The transducer you pick largely relies on your cone angle. So always select the one that will facilitate the type of fishing you take part in. Wider angles are less effective for deeper waters and provide a wider image of shallow waters. You should keep points in mind when looking for your ideal transducer.
Display
The display of a fish finder is also of great significance. Always consider the following things: display size, color, detail, and contrast. All of these things play a key role in helping you discern the returning signals. Another thing you should take stock of is the pixel power of a display. The more pixels, the smoother and clearer your image will be.
Most experts prefer going with a colored display when money isn’t an issue, as a colored display is good at bringing you a clear image even under the sun’s rays. So while looking for a fish finder, it’s important to look into display specs. A big screen size enhances your reading ease. The right display is the one that best suits your criteria. Some displays are easy and clear to read even without taking off the fishing sunglasses.
Cone Angle
Cone angle matters a lot, as the transducer heavily depends on it. Without a cone angle, nothing will work the right way. According to many experts, cone angle is the most crucial feature and works hand in hand with the depth finder’s frequency. Simply put, the cone angle is the width of a beam when it is transmitted and goes through the fishing boat’s bottom. This is known as the cone angle, as the shape it starts with is thin at the top, and gradually widens as it goes deeper into the water like a cone.
This feature is also referred to as the transducer beam angle. A bigger and wider angle will lead to a wider view field for sonar signals. Knowing how it works requires and a detailed understanding of physics and math. In simple words, a wider angle allows a wider vision field but it reduces sensitivity in deeper waters, which can cause distortion on your image.
Frequency
Most fish finders you will see in the market will run either on a low kilohertz or a high kilohertz. The ones operating on the spectrum’s lower side tend to hover around 50 kHz, while the ones operating on the upper end can hover anywhere between 192 kHz and 200 kHz.
It heavily depends on the area you are fishing in. Each frequency option has its own inherent benefits. Since water is fully capable of taking higher frequencies, the scanning sonars operating on the lower end offer deeper penetration. However, they are inclined to have wider cone angles, which means you will have less definition and a higher chance of there being a misrepresentation.
Imaging sonars with higher frequencies perform well in shallower waters. Although they don’t go as deep, they display more definition with fewer chances of distortion. The mechanisms they are built on are quite different from low-frequency models. The area you wish to fish in determines the frequency you should go for. Fortunately, there are models available out there that operate on both higher and lower frequencies, bringing you a clearer picture in deep waters.
If you want to fish in both deep and shallow environments, you are better off buying a unit that is capable of effortlessly switching back and forth between higher and lower frequencies.
GPS Integrated
Global positioning systems or GPS is considered a must-have in this high-tech world, as they are quite convenient in waters. It can be used to find a route back to dry land with the greatest ease. It also goes a long way toward mapping out the coordinates of local ponds and lakes in the United States or anywhere in the world. Users can also mark the sports with high fish densities so they can easily come back again to benefit from your rare finds.
While looking for a fish finder in the market, always look for the best fish finder gps combo. It all comes down to your preferences. However, they are very helpful and convenient. If you think this feature isn’t going to be helpful in your fishing journey, you can save money by picking a unit without a GPS feature.
Best gps fish finders are known as combination units and able to perform both depth sounding and chart plotting. The chart plotter shows the location constantly, while the depth sounder is a fish finder itself. So you don’t need to use a separate device or your unreliable cell phone service to locate your location.
Fishfinders with GPS make it easier to enter different waypoints, allowing you to mark down launch ramps, structures, or fish. Keeping these features in mind goes a long way toward helping you pick the right model.
