Sonar Frequency

Sonar frequency refers to the number of sound waves, or “pings”, that a fish finder transducer transmits into the water per second. It’s measured in kilohertz (kHz), and a transducer can operate at various frequencies depending on its design and purpose.

The sonar frequency determines how much detail can be seen and how deep the sonar can penetrate. Typically, high-frequency sonar provides detailed images but doesn’t penetrate as deep, whereas low-frequency sonar penetrate deeper but offer less detail.

When it comes to choosing the right sonar frequency for a fish finder, it’s a matter of matching the frequency to your specific fishing environment and goals:

  1. High Frequencies (e.g., 200kHz, 455kHz, and above): These are best suited for fishing in shallow waters. High-frequency sonar provides a more detailed underwater view, making it easier to differentiate between individual fish, bait schools, and underwater structures. It’s ideal for anglers who fish in lakes, rivers, and other freshwater environments where detail is more critical than depth.
  2. Low Frequencies (e.g., 50kHz or 83kHz): These frequencies are optimal for deep-sea fishing or any scenario where you need to scan deeper beneath the water’s surface. They penetrate further down but produce less detailed images compared to high frequencies. Therefore, if you’re heading offshore or into deep freshwater lakes, a lower frequency might be more suitable.


CHIRP stands for Compressed High-Intensity Radiated Pulse. Unlike traditional sonar which sends a single frequency pulse at a time, CHIRP sends a continuous sweep of frequencies ranging from low to high. This range of frequencies provides a broader spectrum of information.

CHIRP provides more detailed and clearer images with better target separation, allowing anglers to differentiate between individual fish, bait schools, and underwater structures. It also reduces “clutter” and offers better depth penetration.

While many fish finder models excel in CHIRP technology, we recommend the Garmin Striker 4 CHIRP GPS fish finder for beginners because of its low-price and ease of use.

Side Imaging

Side Imaging (SI) is an advanced sonar technology that offers a visual representation of the underwater environment on either side of a boat. Unlike traditional sonar that looks directly below the boat, Side Imaging scans the area to the sides of the boat using a high frequency sonar beam.

Side Imaging Screenshot

Side Imaging offers high-resolution images, allowing for a clear view of underwater structures, fish, and other objects. This makes it easier for anglers to identify prime fishing spots.

It can cover a wide area, often up to several hundred feet to either side of the boat. This means anglers can scan large areas quickly.

When it comes to choosing a side imaging fish finder, we recommend Humminbird Helix 9 Mega SI+ as it offers the best side imaging in the $1500 price range.

Down Imaging

Down Imaging (DI) is another advanced sonar technology, akin to Side Imaging, but as the name suggests, it’s focused on providing detailed underwater images directly beneath the boat. Down Imaging uses high frequency sonar to produce detailed, almost photographic images of the underwater environment. 

The images from DI are more refined and clear than those from traditional 2D sonar, allowing anglers to easily distinguish between fish, submerged trees, rocks, and other underwater features.

If you are looking for a high-quality fish finder with down imaging, the HELIX 8 CHIRP MEGA DI is the best option in the $1000 price range.

Live View Sonar

Live view sonar, often referred to as “real-time sonar” or “live sonar,” represents a significant advancement in fish-finding technology. Unlike traditional sonar that provides images with a slight delay (as it processes returned signals), live view sonar displays underwater activity in real-time, allowing anglers to see fish movements and responses to their lures instantly.

Anglers can watch fish react to their bait or lure in real-time, allowing them to adjust their techniques on the fly. Many live sonar systems offer high-resolution imaging, making it easier to distinguish between individual fish, bait, and structures.

Garmin’s Panoptix was one of the first to offer real-time sonar views. The LiveScope variant provides even higher resolution images and has become a popular live view fish finder among professional and recreational anglers alike.

GPS and Maps

GPS and maps in a fish finder offer a combination of navigation and location-tracking features that significantly enhance the fishing experience. Integrated GPS ensures that you can easily find your way to productive fishing spots and safely navigate back to your starting point, even in unfamiliar waters.

Premium fish finders offer detailed bathymetric charts, contour lines, points of interest, and sometimes even satellite imagery. Their interfaces are generally more user-friendly, intuitive, and customizable.

Whereas, basic models might offer rudimentary mapping without detailed contours or only a basic GPS for marking waypoints.

If you’re a casual angler who fishes familiar waters and needs a basic device to mark favorite spots, a fish finder with basic GPS would suffice.

If you’re an avid angler, a professional, or someone who frequently explores unfamiliar waters, investing in a high-end GPS fish finder with advanced mapping features would be beneficial. We recommend Garmin GPSMAP 943XSV as the top fish finder GPS combo that offers host of features in $1500 budget range.

Screen Size

Screen size is one of the most noticeable features of a fish finder and can significantly influence its price, display resolution, and the overall fishing experience.

Generally, as the screen size increases, so does the cost. Larger screens require more materials and often come packed with higher-end features. A fish finder with a 3-inch screen is typically going to be less expensive than one with a 12-inch screen from the same brand and series.

Here’s a breakdown of different screen sizes in a fish finder and the features:

  • Smaller Screens (3 to 5 inches): At this size, you’re likely to encounter lower resolutions. While these screens can display essential sonar returns, finer details may be challenging to discern, especially when using features like side or down imaging.

But, these are lightweight, portable, and great for small boats or kayaks where space might be limited. 

  • Medium Screens (6 to 9 inches): These screens often come with higher resolutions, offering clearer and more detailed images. You’ll be able to make out structures, fish arches, and other underwater features more easily.

Medium screens are versatile and suitable for a wide range of boats, from kayaks to medium-sized boats. 

  • Larger Screens (10 inches and above): Typically, the largest screens offer the highest resolutions, ensuring the crispest and most detailed images. They can also accommodate split-screen modes without compromising readability, allowing anglers to view multiple types of data simultaneously. These are preferred by professional anglers or those on larger boats.


A portable fish finder is a device designed to identify fish and underwater structures, much like a traditional fish finder, but with the added advantage of being easily transportable and not requiring permanent installation. Many come as complete kits with a head unit, transducer, carrying case, and power source. Certain portable fish finders come with castable transducers that can be attached directly to a fishing line.

Portable fish finders are suitable for various fishing environments, from boats to ice fishing to shore fishing. They offer flexibility and convenience for anglers who don’t want to commit to a fixed installation or who fish in various environments.

Should You Buy One?

The decision to purchase a portable fish finder depends on your specific fishing habits and needs:

  • If you frequently change fishing locations, boats, or prefer the flexibility of using the device in various scenarios, a portable fish finder is an excellent choice.
  • If you’re a casual angler or someone who occasionally rents boats, a portable model offers the convenience of having your fish-finding tool without permanent installation.
  • On the other hand, if you have a dedicated fishing boat and require advanced features, a more extensive, fixed installation might be more suitable.

We recommend Deeper Pro+ as the top-notch portable fish finder that offers a blend of functionality and convenience. It’s especially suitable for anglers who want detailed information about their fishing spots and appreciate the integration with their smartphone.

What is the best fish finder for a boat

The best fish finder for a boat depends on the type of boat you have. Different boats have varying needs and spaces available for mounting and using a fish finder. Here is a breakdown of the recommended fish finder for different types of boats:

  • Small Boats (e.g., Jon Boats, Inflatables): Due to space constraints, a compact fish finder with a screen size of around 4 to 5 inches is suitable. The Lowrance Hook Reveal 5 or Garmin Striker Vivid 4 are our recommended fish finders for small boats.
  • Kayaks: Portability and battery life are crucial. A small to medium-sized unit, preferably with a portable kit, works best. The Humminbird HELIX 7 or Deeper Pro+ are the top kayak fish finders.
  • Bass Boats: Given the emphasis on fishing, a medium to large-sized fish finder with advanced features like CHIRP sonar, side imaging, and GPS is ideal. The Humminbird HELIX 7 or Garmin Livescope are excellent options.
  • Offshore or Deep Sea Fishing Boats: Here, depth capability and GPS features are vital. Large screens and high-power sonar systems, such as the Garmin GPSMAP 943xsv or Simrad GO12 XSE, are recommended.
