Fishfinder is one of the most useful devices for anyone who is going fishing. The best fish finder will help you find fish in just a small amount of time and also helps you to identify any obstacles under water. It will sure make your fishing sessions easier and more enjoyable.
There are many types of fish finder on the market, offering various types of features and options with very different prices. Therefore, if you want to buy a fish finder, you will find that it takes a lot of time and patience to search for the one that suits you the most. It is best if you can take time to search and list what options and features you will need before going shopping. Otherwise, you will end up buying what is available and what the salesman tells you to buy.
If you do not research carefully and don’t set your own requirement, the chance you buy a fish finder with the fancy options that you don’t need is pretty high. Not to mention it could be expensive, which could turn out to be a waste of money.
In this article, I will help you to go through something you would need in a fish finder for you to make the best-informed choice.
The most important question you should ask yourself is how deep the water you are going fishing in. The answer to this question would be deep water, shallow water or both types. Having the answer to this question will help you chose the cone angle of your transducer and the frequency of the fish finder.
These two features will determine the underwater coverage that the fish finder will able to deliver.
- In deep water, you will need a narrow cone of about less than 20 degrees and a higher frequency of about 192 kHz or 200 kHz. This means that the coverage is not wide but you can look deeper into the deep area.
- In shallow water, you will need a lower frequency of about 50 kHz because you don’t need your fish finder to look deep as there are only shallow levels only. But you will need to it to find fish in a wider area. Therefore, you will need a wide cone angle of about 30 degrees and more. The more cone angle expands, the wider you can see through the fish finder.
- If you want to go fishing in both deep water and shallow water, you can have 2 options. First, you can buy a fish finder with a dual frequency transducer of low frequency and high frequency available. You can also opt for one with a dual beam as well which allows you to switch between narrow and wide cone options.
You can consider not buying dual beam or dual frequency transducer if you are not going to use both, hence saving your money on unnecessary options.
The next important question you should also ask yourself is what type of water you are going fishing in.
There are two types of water which are salty water and fresh water, which are the difference in the density. The fresh water is less dense than the salty water in general. A normal transducer will be able to penetrate much more easily into the water that has lower density, therefore, it would be easier to use a fish finder in the fresh water than in the salty water.
If you are going fishing in fresh water, you won’t need a fish finder that provides much penetration into the water as well.
The last question you should consider is the bottom condition of the area where you go fishing. There will be the soft and hard bottom. The soft bottom will absorb your sonar waves more easily. Therefore if you have a fish finder with lower frequency, your result would not be correct.
In general, buying a fish finder does not require you to know much about its specifications as well as features available. You need to pay most of your focus on the frequency of the transducer as well as the coverage of the fish finder’s beam. You will need to answer yourself a few questions about the depth of water as well as the type of water you are going fishing in and the bottom condition of that particular area. If you fish only in 1 type with one type with one certain level of depth, such as shallow fresh water, you only need to buy a fish finder with low frequency and wide coverage and that is it.
I hope that by reading this article, you can figure out your need and manage to narrow down types of fish finder that you need and are able to avoid other unnecessary options and features which leads to much more money wasted.
