What is good at finding fish? Fish finders. But does the energy emitted by the fish finder scare the fish away?
We hope not. As we'll discuss, if the fish finder scares the fish away, we have all sorts of problems--it makes our fishing hobby less enjoyable, and it can lead to food all over the world shortage.
These are some pretty dire consequences, so let's start debunking the public opinion that fish finders scare fish:
The fish finder consists of two components
As you probably know, a fish finder consists of two parts: a transducer and a dispaly—sometimes simply called a fish finder. As far as we know, no one is worried that the device's dispaly and interface -- will scare the fish.
This means that our real concern is the transducer. Your transducer emits a sonar signal, often called pings or frequency. This is where people worry about scaring fish - sonar is sound for detection, after all.
Commercial Fishing and Sonar
There are no reviews and no studies on whether sonar scares fish -- at least, we haven't found one. However, we can use anecdotal evidence to try to determine whether fish are afraid of the pings from the sensors.
About 3 billion people rely on fish as their main source of protein. If sonar scares away more fish than it helps find, the fishery may abandon it entirely. Instead, as you read this, more sophisticated and powerful sonar technology is being developed.
That's because, even though sonar does scare away fish (and there's no evidence that it does), it does an amazing job of helping commercial fishermen catch those fish.
