Sonar Technology: Side Imaging vs. Down Imaging

Side imaging sends sonar beams to the sides of your boat, revealing fish and structure up to hundreds of feet away. Down imaging provides a detailed view directly below. For freshwater fishing, side imaging helps you scan large areas quickly, especially around points and ledges. Many models combine both with CHIRP sonar for excellent target separation. If you fish rivers with current, see our best fish finder for river fishing guide for specialized advice.

Display Size and Resolution

A larger screen makes it easier to see sonar returns and map details. Five-inch displays work well for kayaks or tight consoles, while seven to nine inches offer better split-screen views. Look for sunlight-readable screens with high resolution for clear images in bright conditions. Touchscreen models add convenience but may cost more.

GPS and Mapping Capabilities

Built-in GPS lets you mark waypoints, follow routes, and view your boat speed. Preloaded maps of inland lakes save time and help you find contours, drop-offs, and humps. Some units offer real-time mapping to create custom charts as you fish. For budget-friendly options, explore our top budget fish finder with GPS picks.

Transducer Quality and Included Accessories

The transducer is the heart of your fish finder. High-quality transducers deliver clearer images and wider coverage. Many freshwater fish finders include a transducer that supports side imaging, down imaging, and CHIRP sonar out of the box. Check for easy mounting options and cable lengths that suit your boat setup. For those on a tight budget, see cheapest side imaging fish finder options for value picks.
