How does a Fishfinder detect fish?  

First, let’s go over what fish finders are and what they do. Generally, a fish finder made up of two parts – a display that is placed in the boat or a kayak if you have a portable one, which displays potential fish and their

depths, and a sonar transducer, which includes an underwater sensor that sends reflected sound waves back up to the display.

The transducer sends sonar waves (sound waves) down into the water. When the sonar wave hits objects (fish or seabed), it estimates the size and depth of the object, and sends that information back to the fish finders display.

Fish finders detect the presence of fish primarily by detecting the air in their swim bladders. The air conserved in the swim bladder changes the sound path and reflects energy back.

The fish finder detects this reflected energy and converts it into fish images on the screen.

So, you’ll be able to locate fish using a fish finder, but you’ll also be able to locate logs, rocks, shallow waters, and other hazards.

How To Read a Fishfinder?

Reading a fish finder is fairly simple. They will give you a rough estimate of the depth of the water you’re in, and the shape of the bottom surface.

This can be very beneficial in choosing lures, weights, and other equipment, as well as avoiding snags. But no matter what you need to be moving for it to work and see anything.

There are hundreds of fish finders on the market, ranging from $50 to several thousand for the best ones.

Like so many other things, you get what you pay for. Basic fish finder models will give little more than very rough estimates, but can still be helpful.

Intermediate fish finder models will offer much more accurate estimates, update more quickly, and pick up more activity.

Advanced fish finder models are very accurate, and can even tell the difference between different types of fish – as well as provide accurate information on their size, depth, and trajectory.
