When comparing different types of fish finders, there are a few key factors to consider: frequency, power, cone angle, and display. Higher frequencies, such as 200 kHz, are ideal for shallow waters and provide better detail, while lower frequencies, like 50 kHz, are better for deep water fishing. Power is crucial for reading at high speeds or in deep water. A wider cone angle covers more area but sacrifices detail. Lastly, consider the display size and resolution for easy reading. Some popular fish finder brands include Garmin, Lowrance, and Humminbird.
