The historical development of fish finders
The journey of fishfinder began with an idea that kept its secret deep beneath the surface of the water. The First World War brought with it the need to make the invisible under the sea visible. This is where the first chapter of our dive into the past opens, which is closely related to... echo sounder is linked - a milestone technical diving equipment.
Alexander Behm, a German physicist and inventor, is a key figure in this story. With his patent from 1916, which described a method for measuring the depth of the sea, he laid the foundation for today's modern Underwater sonar-Technology. Originally intended for military purposes, the echo sounder soon opened its services for civilian shipping and later had a significant impact on the world of fishing.
Military necessity became an instrument of opportunity. The innovative power of a man named Carl Lowrance revolutionized the market. He saw the potential that lay in this device for anglers. It wasn't long before the world welcomed the first fishfinder, which were specifically developed for use in inland waters and on the high seas.
The echo sounder, which once listened for submarines in the depths of the sea, would soon reveal the schools of fish to anglers.
It's been a slow but steady rise from a military technology to an indispensable companion for every angler. Since the end of the 1950s, the fish finder has developed from a barely affordable luxury item into an indispensable tool that is not available in any technical diving equipment may be missing.
- 1916: Patent application through Alexander Behm
- 1950s: Beginnings of commercial fish finders
- Today: standard equipment for anglers worldwide
Today, what was once a revolutionary technology is becoming common practice. Any boat that focuses on the hunt after happiness under the waves, is equipped with an echo sounder that not only tracks fish, but also guides them safely through the vastness of the ocean. Alexander Behm Perhaps he would never have dreamed of this development - and yet it is his invention that changed the world of fishing forever.

Application tips: Use and interpret the fish finder correctly
The art of not only using a fish finder, but also correctly interpreting its displays is crucial to fishing success. Acquiring this knowledge is akin to learning a new language, with the symbols and numbers on the screen forming the words and sentences. In order to master this language, we have to learn Fish finder settings exactly to be carried out and those delivered Evaluate sonar data.
Fish finders can measure water depth, view the structure of the water bottom and locate schools of fish to help anglers find suitable fishing spots.
Settings for optimal results
The setting of yours fish finder should be tailored to the respective scenario. A High frequency echo sounder, for example, provides detailed images of the subsurface and enables accurate Fish detection, which can be particularly advantageous when hunting for smaller fish. However, when searching for schools of fish in deeper waters, a lower frequency may prove more useful as it covers a larger area. Depending on the nature and depth of the water, the situation requires adjusted frequency settings for your depth tracking device.
Reading and understanding sonar data
The heart of everyone Underwater sonar system is the ability to accurately collect and interpret sonar data. It begins by distinguishing between simple structures, such as the contours of the lake floor, and more complex signals that can represent fish movements. It is important to adapt the interpretation of the data to the respective situation and to use experience to recognize the subtleties that can distinguish between a school of baitfish and a single large fish. Analyzing sonar information is more than just reading; it is a combination of experience, knowledge and intuition that ensures you can design your fishing strategy effectively and maximize your chances of catching a catch.
Fishing is a sport that is not only loved by adults, but now also by children. It is a quiet sport that often requires a lot of patience and endurance. Fishing days are perfect for simply unwinding and recovering from the stress of everyday work. To end the day with a successful catch, there are practical fish finders that help locate fish in the waters. They are small and compact devices, which are relatively light and can therefore be easily taken with you.
Since when is there a fish finder?
Those who now believe that the fishfinder is a completely new technology are wrong. The story of the fishfinder begins in the First World War, where different countries have independently invented the echo sounder. The physicist Alexander Behm has at the 07. January 1916 in Germany the echo sounder registered as a patent.
Since that time, technology has continued to improve, making the devices more modern and easier to use. While they were used in World War II to find enemy submarines, in the 20th century Fischer found out that they are also perfect for anglers and divers. Meanwhile, according to various Fishfinder testsThe handy equipment is an essential accessory for any angler.
What is a fish finder?
In our Fishfinder comparison We have already mentioned that this is a special device that has actually been developed to measure water depths. The echosounder measures the time between the emission of the sound and the arrival of the sound from the water bottom. They are typically used to safely navigate ships on waterways to prevent the ship from touching the bottom of the ground.
In today's world, the echosounder is increasingly used as a fish finder. With the help of the device, anglers are able to locate nearby fish. Despite this modern method, luck and patience are certainly needed to make a great catch while fishing.
What affects the image quality of the fish finder?
Basically, the quality of the fish finder plays an important role, as well as the respective model, which in the Fish finder buy is considered. Most devices are equipped with a display that shows by fish, for example, if there is a swarm in the vicinity.
As soon as the device perceives something through the sound waves, a beep sounds. However, this is a kind of snapshot. That means that as soon as you react, it may be too late again. In addition, the sound waves are blocked by plant remains or garbage that floats in the water. They can not get past it and thus show something, but no fish. It is therefore important to choose a high-quality fishfinder that can avoid obstacles.
Which different models are available at the fish finder?
As you already know in ours Fish finder comparison There are many that you could read different modelsthat can be used individually. A basic distinction is made between a mobile and stationary fish finder. Below is an overview of the respective differences:
Mobile fish finder
This is a model, which does not have to be fixed, but is mobile. This is especially advantageous if there is no own boat for fishing. However, it should be noted that as a rule the sound waves are already emitted above the water. As a result, the result is usually affected, as thus the boat is hit. The important thing is that when Fish finder buy a model is chosen which is adjust automatically to avoid such problems.
Stationary fishfinder
As the name suggests, this model is permanently installed on the boat. Mostly the installation takes place below the boat, where the ultrasonic waves can be discharged directly into the water. In this way, the best possible result is achieved without disturbing factors being in the way.

· transmission power
The transmission power is immensely important for a fish finder. Je higher the performance the better the results will be shown on the display. The best fishfinder have a transmission power that is between 500 and 4.000 watts. While a hobby angler needs a transmission power of 500 watts, a professional angler needs a wattage of up to 4.000. Especially in cloudy water Performance plays a big role so that the fish are clearly visible here too. At very low power, the difference between floating particles and Mostly fishing only blurred or not displayed at all.
· frequency range
The higher the frequency range, the more detailed the picture can be displayed. The optimal range is between 50 and 200 kHz.
· Display
Modern displays are usually equipped with an LCD display. They offer one high resolution and ensure high contrasts. A display that also works with grayscale is also very advantageous, as this makes the contrasts even easier to see.
· Sound wave direction
Most fishfinders are equipped with two sound wave orientations, Downscan Imaging and Side Scan Imaging. Downscan Imaging scans the entire area below the boat. Sidescan imaging, on the other hand, ensures that the sound waves are transmitted to the left and to the right.
