A fish finder is an electronic device used by anglers to locate fish underwater. The device uses sonar to detect fish and then displays the information on a screen, usually in the form of a graph or an image.
Fish finders can be used in both freshwater and saltwater, and they come in a variety of sizes and shapes. Some fish finders are portable and can be used from a boat, while others are permanently mounted on the boat.

Conclusion
A fish finder is a tool that uses sonar to locate fish underwater. The device works by sending out a sound wave that bounces off of fish and other objects in the water. The wave is then received by the fish finder and displayed on a screen, which helps the user to locate fish.
Fish finders can be extremely helpful for fisherman, as they allow them to locate fish that they may not be able to see otherwise. In addition, fish finders can also be used to track the movement of fish, which can be helpful in determining where they are likely to be at certain times of the day or year.
Overall, fish finders can be a valuable tool for anyone who wants to improve their fishing success. By helping to locate fish, track their movement, and providing other useful information, fish finders can give fisherman the edge they need to catch more and bigger fish.
