3. Top Fish Finders by Type of Sonar
Every few years there seems to be some type of new sonar technology that pushes the envelope for consumer grade fishing electronics. For many years, flashers were the deal, like Lowrance’s famous “Green Box” locator, and Humminbird’s equally renowned “Super 60” flasher. From there, fish finders turned to paper “graphs”, and then LCD displays that revealed more information about what was below the boat.
Then in the mid-2000’s, Humminbird was the first company to release affordable side imaging to the consumer, and it was a smash success. From that point on there has been an arms race that some have come to call the “Sonar Wars“. The guide below will help you understand each of these fish finding technologies and help you decide if you need them.
Kayak Fish Finders
Kayak fishing has exploded in popularity in the last five years. If you are looking to get into kayak fishing, now is a great time. There has never been so many awesome fishing kayak options and quality fish finders to put on them. There are several really good 5 and 7 inch models that have awesome screens and are easy on your budget. See all our Kayak Fish Finder Reviews, or check out our Top 3 recommended Kayak Fish Finders.
Portable Fish Finders
Portable fish finders are units that are easily attached to and removed from a boat. A portable unit can be useful if you take infrequent trips to the lake, rent boats, or have a smaller fishing boat that isn’t conducive to a permanently mounted fish finder. These units typically come with a separate battery that you stow in the carrying case
There are also castable fish finders, which are basically a transducer pod that floats, and a smartphone app is the fish finder. These kinds of fish finders are excellent for fishing from shore or from small watercraft.
Fish Finders for Ice Fishing
Ice fishing requires a special type of unit to be effective in catching fish under the ice. You are working your bait vertically so you want to be able to see fish under your bait, as well as see your bait as it drops down the water column.
The first thing to look for is a good flasher display. Mechanical flashers tend to breakdown more frequently and require repairs, so for that reason, we suggest getting a digital flasher.
Most 5 inch portable units now have a flasher option in the available views. You can also do a split screen to see traditional 2D sonar. With these two views, you can see fish and your bait under the hole in the ice.
Best Down Imaging Sonar
Down imaging uses a transducer that emits a single extremely thin slice of high frequency sound waves to create a lifelike 3D appearance of whats below your boat. When stacked up and painted on your fish finder, these thin slices of sonar returns make it much clearer as to what is below the boat. What might look like a blob of “something” in standard sonar, is instantly revealed to be brush, rocks, fish, or other kinds of structure.
Each manufacturer has their own version of down imaging sonar; Humminbird’s Down Imaging, Lowrance’s DownScan, Garmin’s DownVü, and Raymarine’s Dragonfly. The imaging looks very similar on all the brands, so it’s really up to you to look closely at screenshots and specifications and decide what will work best for you. With imaging being more or less equal, look for the best and largest screen, as well as for the mapping capabilities that will meet your fishing style.

Best Side Imaging Sonar
Where down imaging uses one sonar beam looking directly towards the bottom, side imaging uses two beams that are angled slightly upward in both side directions. The two beams together create photograph-like images of the lake bottom on both sides of your boat, revealing contour changes, bottom composition transitions, fish, and structure all at the same time.
Side imaging is an extremely useful tool for searching out fish holding structure on the lake. It can significantly reduce the time it takes to find fish, making you more efficient, allowing you to spend more time trying to catch them.

MEGA Side Imaging: If you are looking for the best possible images in a fish finder, there is nothing better than the Humminbird MEGA units. They utilize 1200 KHz frequency (1.2 MHz) to get ultra clear images both side and down looking sonar. MEGA is only available in the HELIX 9, 10, and 12, as well as the SOLIX SI models.
Best Side Imaging Fish Finders
360 Imaging & Scanning Sonar
As great as they are, down and side imaging have a few drawbacks. First, you need to be moving forward to be able to get a clear picture. Idling speed is best, but you can slow the scrolling speed down to show a good picture while fishing from the trolling motor. The second drawback is that you can only see what you have already passed over with your boat. It’s great to see the structure, but it doesn’t do you much good if you’ve already passed it.
Humminbird came out with an innovative solution to this problem, called 360 Imaging. 360 Imaging uses a rotating transducer to sweep in a full circle around you and the boat. This allows you to see in front of you, behind you, and to all sides without moving at all. The rotating transducer refreshes the screen even while you are stationary, allowing you to see targets in front of you to cast to. Now you can clearly see casting targets such as pockets and turns in the weed-line, as well as brush, stumps, and trees.
The 360 Imaging transducers are a fairly expensive add on, but we truly believe it can be a huge leap forward for serious anglers, especially bass and panfish anglers. Most of Humminbird’s higher end units are capable of displaying 360 Imaging data, as long as you have the most recent software updates. We have used and recommended the bow mounted 360 unit, which you can see the review here.
CHIRP Fish Finders
CHIRP sonar is one of the newest technologies to come to fish finders that the average Joe can afford. Lowrance and Garmin and helped push this type of sonar into the mainstream, and now Humminbird and the others are starting to follow. You are probably wondering what exactly is CHIRP, how does it work, and what are the benefits? You aren’t the only one, so here is a short primer.
Where regular sonar uses a fixed frequency, such as 83 kHz or 200 kHz, CHIRP transducers transmit longer sweeps across a range of frequencies. CHIRP transducers are essentially putting many times more sound energy into the water column than a traditional transducer, making it much easier to detect objects in the water column. This also means objects in the water can be viewed with better clarity, with better target separation, and at greater maximum depths.
CHIRP has been normally been relegated to saltwater fishing boats, where they need the greater depth capabilities, but the fish finder manufacturers are finding ways to affordably process the CHIRP signals in a way that benefits the typical freshwater fisherman in shallower water. For some of the best units with CHIRP, check out the below article, as well as the excellent primer video from Lowrance.
Best Fish Finder GPS Combos
Regular 2D sonar uses a cone shaped sound wave to ping the water column directly below the boat. The higher the frequency, the narrower the cone. In general, the narrower the beam, the higher definition you will see on the screen. The lower frequency beam width and a wider cone angle will give you more coverage area, which can be helpful when searching for fish.
When your boat passes over a large fish, or the fish passes through part of your sonar cone, it can appear as an arch. It takes a very specific circumstance to display an arch on a fish finder, so do not be alarmed if you do not immediately or always see the arches. Sometimes the fish look like thin lines, ovals, or balls, it just depends on the speed of your boat, and where the fish are in the cone.
When you see a fish finder advertised as “dual beam”, this just means it has the ability to use both beams at the same time. You can usually view them side by side, blended together, or on separate screens in order to help you understand what’s happening below your boat.
All of the top fish finders today will be GPS combo units. These units have 1 or 2 SD or Micro SD card slots for using mapping cards such as Navionics or Lakemaster. Lakemaster map cards are exclusive for use in Humminbird fish finders, while Navionics can be used in almost any brand.
In the past few years there have been exciting advances in mapping technology coming out, such as DIY mapping software like AutoChart, AutoChart Live, Navionics SonarCharts, and Insight Genesis. Some cards like Lakemaster PLUS and Navionics Platinum+ are also offering Satelite Overlay as a way to enhance your lake maps.
