How to choose the Best Fish Finder in the Market

Fishing can become a very expensive hobby in case you don’t choose very well the products you want to buy. That’s why we made this list with all the details you need to know before purchasing a fish finder.
A fish finder allows you to identify if there’s fish in the water at the moment you’re fishing, and then you can catch them at the exact moment they are close.



It works identifying the electronic impulses reflected by the fish and turning it into information on the screen of the fish finder.
Nowadays it is available in so many different types and sizes, so the five elements that we are going to talk below are the keys for buying the best fish finder that applies best to your needs. More information :


Do you often get confused about what frequency to choose when buying a fish finder?
You should always think about the water conditions where you’re going to use the sonar, the deeper you use it, the lower the frequency should be.
The transducer may have the following frequencies:
Single: it’s only possible to use one frequency on this transducer;
Dual: in this model, you can either use it for shallow water, deeper water or both of them at the same time;
Multiple: it can operate at many different frequencies
The most common frequencies range from 50 to 200 KhZ frequencies, but of course, there are lower ones, for more professional use, and there are higher frequency ones like 400 KhZ, that have a more specific use.


Power is all about the W (wattage), the greater it is, the faster your fish finder will make the readings, and deeper, but again, it depends on the use you’re going to make.
For shallow water: You can choose one fish finder that has a lower W, it will probably be more budget-friendly;
For deep water: buy one with more watts. It is likely to be more expensive, but your readings will be better.
The wattage can range from 100 W to 1000W.
With the same amount of power, a 50 kHz transducer can show readings deeper than the 200 kHz one.


You may be thinking that size doesn’t matter, but you will end up thinking differently after struggling to see something on the screen if it is too small and doesn’t have a good resolution.
There are two important details to consider about screen resolution: pixels and size of the screen.
Pixels: choose the screen with more pixels if you want to see details. If you don’t know what pixels are, they are little dots on the screen, that when combined and in quantity provide a good quality image;
Size: choose a good size screen, a big one, because you have to remember that you will be using it, probably, under the sunlight, and with a small screen it will become a very hard task to see numbers, data, and details.


Whether you should buy a colored screen or one that only supports the grayscale, it depends on your budget.
Black and white screens are good if you’re on a tight budget, the most basic ones should only have this feature available.
The bad thing is under the sunlight is harder to see on the black and white screen. In color displays, it is easier to read numbers, data and see details, under any light.

The last but not least important aspects to consider when looking for a fish finder are the cone edges and the beams.
Think about the cone angle as an upside-down ice cream cone, pointy at the top and wide at the bottom, the deeper in the ocean it gets, the wider the base of the cone will be.
Your best option would be to get one at an angle of 16 to 20 degrees.
With time and experience, you may want to advance to the fish finder version that has more beams, so it helps you cover more area in the ocean, and consequently get more fish.
