What does a depth sounder do?

Depth sounders (or echo sounders) are a type of SONAR system used in marine navigation to determine the depth of the water or to locate and visualize objects beneath the waves. They are used as both a navigational and charting aid as well as to help commercial fishing vessels to find fish.

How does a depth sounder transducer work?

The main component of a depth transducer is the piezo- ceramic element. It is the part that converts electrical puls- es into sound waves, and when the echoes return, the piezoceramic element converts the sound waves back into electrical energy.

What is the difference between a depth finder and a fish finder?

This is more commonly utilized for shallow water depth detection, when a graphic display is not required. A “fish finder” uses the same or similar transducer and actually gives a graphic, video image of the water and bottom under the boat, as well as several seconds or minutes history.

Do I need a depth finder on my boat?

Are fish finders really necessary? Fish finders are not needed in order to locate and catch fish but they do provide highly valuable information like water temperature, water depth, bottom topography, the presence of fish, baitfish, as well as structure such as weeds, rocks, laydowns, and shelves.

Is a depth sounder a fish finder?

More and more boaters are using the electronic device they purchase for a fish finder also as a depth finder.

How does a depth finder work on a boat?

Part of sonic or ultrasonic waves, which have been transmitted, reflect back to the source when they hit an object (e.g. fish school or seabed). A fish finder uses this ultrasonic reflection characteristic. The ultrasonic waves from the fish finder are transmitted directly underneath the boat.

Does a depth finder find fish?

By using a large number of very direct pings, a fishfinder can determine accurately not only whether or not there appear to be fish present, but whether or not there are underwater obstructions, debris, or other objects the fish are hiding in/under.
