Fish Finders Buying Guide : Things To Know!

How Helpful Is A Fish Finder?

If you know how to use it properly, Fish Finder is an incredibly useful tool. It's more useful to find the off-water structure, monitor depths, and pay attention to the water temperature changes.

A fish finder has two main parts: a transducer and a display unit. The transducer sends out sound waves and listens for echoes. The display unit acts like a small computer—it takes those echoes and turns them into pictures that show fish, plants, and the bottom of the water.

In short, whether you're fishing in freshwater lakes or out in the ocean, a fish finder helps you identify hotspots, track fish movement, and avoid underwater obstacles.

What Are The Types of Fish Finders?

There are several types of fish finders, each designed for different needs:

  • Standalone Fish Finders – Great for beginners or those on a budget. These focus solely on sonar data without GPS functionality.
  • Combination (Chartplotter) Fish Finders – These include both sonar and GPS mapping, which helps you mark waypoints and navigate waters more effectively. Ideal for serious anglers or boaters.
  • Networked Fish Finders – High-end units that connect with other electronics like radar, autopilot, and AIS. Perfect for larger boats and advanced users.
  • Castable Fish Finders – Compact devices you cast out with a fishing rod. They sync with your smartphone, making them great for shore or kayak fishing.
  • Ice Fishing Fish Finders (Flashers) – Specifically designed for vertical fishing through ice holes. They provide real-time sonar feedback with color-coded displays.

What Are The Different Sizes of Fish Finder?

Fish finders come in a variety of sizes, mostly defined by their screen dimensions:

  • Small (3” to 5”) – Portable and budget-friendly, perfect for kayaks or small boats.
  • Medium (6” to 7”) – Balanced size with good visibility and functionality, ideal for most recreational boats.
  • Large (9” and up) – High-definition, split-screen displays with lots of features. Great for offshore boats and serious anglers who need advanced detail.

What Are The Most Popular Brands of Fish Finders?

Some of the top fish finder brands trusted by anglers include:

  • Garmin – Known for high-quality GPS integration, user-friendly interfaces, and reliable sonar technology.
  • Humminbird – Offers advanced imaging like MEGA Side Imaging and excellent mapping features.
  • Lowrance – A favorite among tournament anglers, known for their CHIRP sonar and wide screen options.
  • Raymarine – Offers crystal-clear visuals and integrates well with marine electronics for larger vessels.
  • Deeper – Specializes in castable, app-connected fish finders for bank and kayak anglers.

What Is The Best Speed For A Fish Finder?

Fish finders generally work best at slow to moderate speeds. For the most accurate readings, especially when using features like Down Imaging or Side Imaging, a speed of 1 to 6 mph is ideal.

At higher speeds (over 20 mph), some detail can be lost or the sonar may skip readings. However, many newer models handle higher speeds better due to improved transducer technology. When scouting or trolling, keep it slow for better accuracy and detail.
