Do Fish Finding Devices Drive Fish Away

Fish finding devices are for detecting fish underwater, just as the name suggests. But the sound wave it emits, does it drive the watery animals away?

Let's hope for the best only. We will discuss this topic here, and if this happens that fish hated the fish-finding devices, then our beloved hobby will not find ground anymore, and there will be a huge crisis of fish around the globe. We must think positively here, and without depending on the deity here, we need to check the scientific facts and reasons to check if a fish finder scares the fishes away from your well-laid trap.

Also, if it ever happens, the world will be deprived of delicious fish, which will be a dangerous thing for those living on earth. So, in this article let's find some facts on the misconception that fish finding devices drive fishes away from the traps. Only when you know the truth, you will get more freedom to use a fish finder.

A fish finder has two parts

A fish-finding device is made of two parts, the first one is a sensor which is known as the transducer, and a cone-like section which is the main finder. As per our knowledge, the control head section isn't the problem, but the interface and the display screen are driving the watery animals away from the traps.

(However, if you drop the expensive device into the ocean, and start to scream about the loss you just faced, may scare the fishes away farther than the device interface itself).

This leads our focus on the sensor or the transducer part of the device, which produces sound waves, and this is known as frequencies or pings. People are scared of Sonar technology as it uses sound waves to identify the underwater movement of fishes.

Sonar technology and commercial fishing

As per our knowledge of Sonar technology, there are no studies, or peer reviews and no other research has been made on the ill effect of the system on fish. However, we can rely on the informal proof that whether or not fishes are scared of the sound waves from a fish finder.

Let's begin with commercial fishing. These fishers use heavy-duty fish finder devices than the hobbyists like us.

Almost three million people depend on fish, and it's regarded as the main protein source for those people. If the use of fish finder devices ceased, then the fishing industries around the world would shut down gradually. If you research a bit, you will find that more powerful and elegant fish finder devices are developed in this era.

This is mainly because even if the sound wave technology drives the fish away (which it doesn't as there is no solid proof), it does a perfect task to help the commercial fishing business.

Sonar and fishing in shallow water

Commercial fishing is done in the ocean, but when you are fishing in shallow water like it's ten feet deep, will the fish still scare away by the sound wave from the fish finder device?

Fortunately no, as there are no solid proofs on this subject. Many fishers have used fish-finding devices to catch fish in shallow waters, and they didn't report any issues. However, some fishers are determined that the Sonar device has driven the fishes away from the traps.

Here, we have to give you an example about the GC Jetski's test video on YouTube, if a fish finder device drives the fish away. Jetski used a very easy method, as he placed the Sonar transducer over an aquarium to check if the fishes are scared of the sound wave.

If you do not want to watch the video, let us tell you that he revealed the truth about the scaring fish away myth, and he proved it in only one-foot aquarium water. For a brief second, the fishes cleared the nearby area, but they came back as if there was no sound. The test proved that in shallow waters, fishes may drive away for a bit, but they will eventually return as if nothing happened. And the test was just on one-foot water, so when you are fishing in ten feet, what do you think will happen? The fishes will not even notice anything.

Fish finding device for shallow water fishers

Keeping this in mind, when you are reading our reviews on fish-finding devices for shallow water, you must go for the powerful device, because fishes do not drive away from the fish-finding devices.

You can choose a device that has a higher frequency and has better control of the interference. You won't need a higher depth penetration when you are fishing in the shallow water, so we suggest that you should opt for eight hundred kHz or higher CHIRP technology Sonar, this will fit your requirement perfectly.

Have a nice fishing experience!
