Specification Comparison and Reviews

Instead of trying to figure out which is the best fish finder just by reading reviews, comparing three features and then ranking the fish finders from 1-100, makes it easy to see which one comes out on top and will allow buyers to make an informed decision when they go shopping.


You want to make sure that your fish finder is working correctly and will show much detail, so you can quickly determine what is below you in the water.

The frequency of your chosen fish finder will let you know at what rate the sound waves can pass through the water and then be measured.

The lower frequency is best for deep or saltwater fishing, while higher frequency fish finders are ideal for fresh or shallow-water fishing.

Look for a wide range if you are interested in being able to take your fish finder with you, no matter where you are going to be fishing.

Garmin Striker 7sv

With transducers of 77/200 kHz, the Garmin Striker 7sv is relatively powerful.

Because it can broadcast more than one waveform at a time, you can be sure not to miss any smaller fish in deep water.

This fish finder can release 455, 200, and 77 kHz frequencies quickly so that you can see deep in the water, as well as smaller items that may be closer to your boat. The down imaging is 260-455-800 kHz, and the side imaging is 260-455-800 kHz.

Hummingbird Helix 7 SI

The Humminbird Helix 7 SI has side and down imaging of 83/00 kHz, as well as 2D imaging of 455 kHz.

This is not as powerful as other options on the market, which means that you may miss smaller fish under your boat if you are fishing in deeper water.

Humminbird Helix 7 SI 50Points

The Garmin Striker 7sv is the clear winner here, with strong frequencies that are incredibly easy to adjust while you are on the water.

This makes it very simple to control what you see on your screen, and to make changes so that the picture is as clear as possible, which will allow you to tell what the fish are and where they are so that you can have a great day out in the boat.

While other fish finders offer similar frequencies, the Garmin Striker 7sv is superior and known for being incredibly powerful.

Pixel Rating and Screen Quality

In general, the more pixels that you have on your screen, the better your view is going to be. You’ll enjoy much more precise images of what is below the water when you opt for a fish finder that has a higher pixel rating.

Of course, it’s important to remember that the pixel rating also depends on the size of the screen, as larger screens will be able to support more pixels. Also, the price of the unit will increase as the pixel rating does, so that is something that you have to bear in mind when making your final choice.

Garmin Striker 7sv

The pixel rating on this fish finder is a typical 480 x 800 pixels, but it has the added benefit of WVGA color that makes it very easy to tell the difference in items below your boat, without a lot of hassle or frustration.

Hummingbird Helix 7 si

The 256 color TFT display on this fish finder has 480 x 800 pixels, which is more than enough to see under the water in the boat.

While the display is easy to read, there is often a little stretching on TFT displays, which isn’t desirable.

Humminbird Helix 7 SI

When considering pixel rating and overall screen quality, you will want to choose the Humminbird Helix 7 SI.

While the pixel rating is consistent across the board, the type of display matters, and will have a huge bearing in the overall quality of what you can see on your screen, and how quickly you can find and catch your fish. Humminbird’s display screen is better than the Garmin’s.


You want your fish finder to be as efficient as can be so that you can see clearly under the water. The watts used by your finder will determine how deep the transmission can go.

Shallow water will only need lower watts, around 100-watt, but saltwater and deeper water fishing will require a fish finder that has a higher wattage.

This is because you want the transmission to penetrate deep into the water, and saltwater has a higher absorption capacity, so you need a higher wattage to compensate for being able to see clearly.

Garmin Striker 7sv

The Garmin Striker 7sv has a transmit power of 500 watts.

This means that it will do well in shallow water, as well as water that is a little deeper, however, if you like to deep-sea fish, you will have a little trouble seeing what you are looking for.

Hummingbird Helix 7 SI

With a transmit power of 500 watts but 4000 W peak-to-peak, you will be able to see even into deeper saltwater with this fish finder, making it an excellent choice if you like to fish on the ocean or want the option to be able to.

Garmin Striker 7sv
Humminbird Helix 7 SI

While the Humminbird Helix 7 SI’s power is in line with the Garmin Striker 7sv, it takes the lead in this category because of its ability to have peak power at 4,000 watts.

You won’t ever have to worry about how deep you want to fish, what the water is like, or whether or not there is debris floating beneath you, as this fish finder will give you a clear view of everything underneath your boat, without any problems or hassles as it automatically and quickly updates your view.
