This is a sonar instrument that is made specifically to detect fish underwater. It detects reflected impulses of sounds. All the reflected electronic impulses are converted into information which is then displayed in a graphic on the screen of the machine.
Also, these units measure the depth of the locating underwater debris, water, and the bottom structure. The Picture that is typically found on the screen of the device can represent one fish that is in the form of a small icon.
How to Buy the Fish Finder
Nowadays there are many fish finders and types of fish locators that have come to the market. Therefore, it becomes difficult to know the right unit to meets your style and needs.
You need to be very careful when buying so that not to make any mistake that might cost you a lot of money. The first thing that you are required to put into consideration is whether the tool will help you to catch a lot of fish.
To reduce the hassle that comes with buying a new gadget, it is essential that you consider factors such as a Transducer, power, display, portability, and frequency. Below are several factors that will guide you in purchasing the finder.
Factors To Consider When Buying
1.Display [color, size, and resolution]
The display is a very crucial factor that you need to find. It is all about pixel since, if you have more pixels, you will be able to see more details. For you to get a sharper image and good resolution, you will need to invest a lot of cash. The displays of these devices come in different sizes.
For instance, a bigger screen is likely to give you a clearer and good picture. It is also easier to differentiate on it all the information that usually displayed like numbers and echoes. Also, you can decide to choose either color or black and white depending on your budget.
If you are working on a tight budget, then black and white will work for you. The importance of color screen includes easier viewing of the screen in bright light, showing greater details of many colors and simpler ways of viewing what is underwater.
When buying a fish locator, you need to purchase the unit that has the right frequency. The frequency is closely related to the angle of the cone. Most transducers, you are likely to find frequencies such as 50, 83,192 and 200 kHz.
High frequency will provide you with more detail on the screen. Thereby, you need to choose a model that has a higher frequency. You can look for units that have dual, single or multiple frequencies.
This is the major part of the fish finder. The transducer works by sending sound waves and detects what is in the underwater. The sonar sound that it sends into water is then picked up by the transducer.
This signal is later translated into an image. An essential feature in the transducer is the cone angle. Selecting a wider cone will offer you wider coverage of underneath water enabling you to locate more fish.
Power is an important feature that you need to look out for before purchasing a fish finder. The power measure of these devices is watts. When the unit has a higher wattage, it becomes more efficient and provides a better speed of showing readings.
When working on shallow water, you can consider using a device with less wattage. AS such, if you are planning on fishing in deep waters, it is recommendable that you look for more powerful units.
When choosing a fish locator, it is always your choice to pick a portable or a fixed unit. However, buying a mobile unit is a better option if you like ice fishing.
The portable unit comes with its carrying bag and battery power supply. The device comes with a transducer that is usually attached to the transom. On the other hand, a fixed unit will work well with the watercraft owners and settled fishers.
Benefits of Buying Fish Finder
In this era, the effects of technology can be felt in almost every industry. Advanced technology can be experienced even in fishing about modern fishing equipment.
A fish finder is a perfect example of the technological advancement in the fishery. Fishfinders are electronic devices that are very helpful during a fishing excursion because they help find more fish within the shortest time possible.
A fish finder is a fantastic tool that can be beneficial to a beginner as well as professional fishers. Here are some of the reasons why you should use a fish finder the next time you go fishing.
- Determining the location of fish
If you are a bigger, one of the possible challenges that you will face when fishing is locating fish. With a fish finder, determining the location is not a big deal since you can see the location of the fish you want underwater on a big screen.
Boats that have fish finders installed will help you determine the presence of fish quickly. With a tool of this kind, locating a school of fish is not tough.
- Determining Depth
Before placing bait underwater, the first thing that you should think about is determining water depth. You want to be sure that you drop your bait in the correct location underwater. It will help you do that and assist you in fish in the deepest part of the sea.
- Guessing Fish Size
Many people are excited about the catch. At times, t’s hard to know the size of your catch because you can’t see inside the water. However, the screen of a finder allows you to guess the size of the fish when it is still underwater. Therefore, you will get home with your target fish.
- Assuming The Number of Fish
Considering the number of fishes that a school has is almost impossible. With a fish finder, making that assumption is something that can be done without strain.
Assuming the number of fish is possibly the best thing that you can do before you start fishing. Check on the screen of the finder to see the number of fish where you have or are about to place your bait.
- Understanding The Speed of Wave and Water Temperature
Many fishers don’t know the speed of the wave, but with a finder that has a GPS, it is possible to understand waves. Understanding the speed and turn of wave help avoid hassle during fishing.
Fishfinders are designed in a way such that you will get wave alert even from a longer distance. Also, you can determine the temperature of the water if your finder is GPS enabled.
Frequently Asked Questions (FAQs)
- How does transducer work?

- Why is portable fish finder beneficial?
Answer: Portable fish locators are helpful since they are not bulky and so can move with them from one place to another.
They normally come with their carrying bag and battery power supply. Portable units have a transducer that is already attached to the transom with the help of a suction cup.
