If you are kayak fishing, you might want an option which is more portable and light, so you can easy transport it around with you.

If you are a serious angler and you enjoy the sporting side of it, you might want an option which gives you the ultimate experience. If you want to record all of your data and view two displays at once, you will probably be looking at an option with a larger screen.

fish finder how they workSo, you know you need a fish finder, but how do fish finders work? They use a transducer to send out a sonar signal under the water. When this signal reaches an object, such as the floor or a fish, the sonar wave estimates the size of that object and the depth.

The sound wave is returned to the fish finder as an echo. This information is fed back to your device, and a picture is created on your screen. This image enables you to see what is beneath you.

The image you see on your screen will show you how many fish are down there and how far away they are from you. They will also show you objects in the water other than fish, so you will be able to see any hazards coming your way.

They can show you items in the water, such as logs or rocks and alert you to shallow water. Some devices can also show you the temperature of the water so that you can fish as efficiently as possible in that area.

Fish finders are an incredible hand tool for the modern angler, and technological advancements mean these devices are getting better and better.

Display clarity and quality are increasing, and the software packages are better. You are getting more and more for you money when you invest in a fish finder.
