A fish finder is a device used to locate fish underwater. It does this by emitting sound waves and measuring the time it takes for the waves to bounce back. The data is then used to create a map of the underwater terrain and any fish that may be present.
Fish finders are an important tool for kayak anglers because they can help to quickly and easily locate fish, even in deep or murky water. This can save a lot of time and effort, and can help to improve the chances of catching fish.
