A good display will offer better resolution, and a hi-resolution screen will allow you to see the data more clearly. Big screen size will help you to see different sonar data at the same time. Some fish finders show multiple sonar data at the same time.

There are CHIRP sonar, DownImagin/DownVision/DownVu, StructureScan, SideImaging/SideVu and more. These are to make sure you get the data more accurately. An advanced sonar system’s fishfinder is likely to cost you more than a typical fish finder.


A transducer is an element which transmits the sonar waves to the water. Most of the time, fish finders will come with transom mount transducers. These are quite easy to install and use. Some advanced fish finders with advanced sonar technologies might require you to get additional and different transducers to work.

Advanced fish finders allow you to get more navigational features along with the GPS function. Follow the chart above to see which kayak fishfinder has GPS. You can also buy Kayak GPS devices.
