Higher frequencies reach out to localized places and may not spread a lot and work better in shallow waters and give a clearer picture. Low frequencies spread out better and cover larger areas and give a broader view of the place you want to look at. Fishfinders may come up with adjustable frequencies so that you can focus better and adjust the high and low frequencies in your gadgets and use it as per your needs.
