Buyer’s Guide: What to Look for When Buying Fish Finder for Small Boat
While looking for the best fish finder for your small boat, you need to consider many things. Some of the important features you should think about are size, color, technology, scanning, power, and transducer.
Here we have covered all the things you need to know when searching for different models.
Not all fish finders come with the same frequencies. Some fish finders have multiple, dual or single frequency transducer. The frequency is a thing which you must consider because it is the most important feature.
High frequency means more detailed images. It is because such models direct more sonar waves and collect a more accurate image.
If you are fishing in shallow waters, high-frequency models are the great choices. In contrast, if you are going to fish in different water bodies, you may go for a fish finder with multiple frequencies.
In terms of scanning, fish finders are divided into two types. One type is with side scan and other with a down scan. Scanning is also known as a viewing angle.
Fish finders with down scan imaging give the maximum details relative to depth. While fish finders with side-scan offer an extensive view of the water with great focus on width covered than depth.
Which one you should choose, depends on the type of water body where you fish. If it is shallow water, the side scan imaging is the right option. In contrast, if you are going to fish in deep waters, the down scan imaging is the ideal choice.
The screen resolution may not a critical factor to consider but it is still important as more pixels enable you to get a more precise image that is easy to read. You need to go for more pixels if you want clear results and sharp images.
In general, you should look for 240×160 screen resolution which is considered a minimum.
If you are more thoughtful about the quality of the image, you may look for more resolution and a big screen. Such models are a bit costly but offer sharp and quality images that are easier to read.
Another important factor to consider is the power which depends on the type of water and your plan to use the fish finder.
High wattage means you will be able to see the information readings quickly. Power also has an impact on its depth; therefore the high wattage enables the unit to go deep in water.
On the other hand, less wattage means a slower model which is good for shallow waters.
One of the most important things to consider when looking for a fish finder is the transducer. It is the part of the fish finder which emits the sonar waves to water and receives it.
The transducer directs the sonar signals to the water and then collects them once they rebound off the underwater objects.
The signal information is then received at the main unit that transforms it into an image. Consequently, you will get an idea of what is going on underwater.
Many models come with transom mount transducers that are easy to install, mount and use.
The screen of fish finders comes both colored and black and white. Oldest type fish finders have screen display in black and white.
Such models are cheapest but the user experience of these fish finders is limited.
The color of the screen affects user experience in determining how good a person can apply the information gained by the transducer.
With the colored screen, you can get enhanced detailing and much easier to read the image.
A colored image on a fish finder enables you to visualize the information material with more details.
It will help you to understand and see what is going on in underwater and it becomes easier to read in sunlight.
