One of the best ways you can get an advantage in the water over the fish to catch them is by investing in a fish finder.

However, any angler will tell you what a daunting experience buying a new fish finder actually is because there are many brands, and each of them manufactures dozens of models every year.

Thankfully, there is only a handful of brands that is worth looking at, and one of them is Humminbird,

The company has a lot of great products to offer, so we curated our Humminbird fish finder reviews.

We will discuss five of their amazing fish finder models in detail so that you can make an informed decision before buying one.

1. Humminbird HELIX 5 CHIRP SI GPS G2

The Humminbird HELIX 5 CHIRP SI GPS 2 shares a very similar design to its predecessor, but the insides have certainly had an upgrade.


Here are the key features you would expect from HELIX 5 G2:

  • Imaging

CHIRP 2D sonar and CHIRP imaging enable the Humminbird HELIX 5 CHIRP SI GPS G2.

They allow the sonar to cover a broad range of frequencies instead of only one, helping create a far-better clarity and separation between the structure and fish.

  • Controls

The device comes with an improved keypad UI, as well. You can easily take snapshots by long-pressing the Mark button while a short press will just lay down a waypoint.

The checkmark button on the Humminbird HELIX 5 CHIRP SI GPS G2 will toggle the frequency, and lastly, the "+" and "–" buttons are the zoom buttons that control the sonar sensitivity.

Each of these enhancements is made to be convenient for the angler and can save a lot of time on the water.

  • Mapping

This fish finder also has live mapping with AutoChart Live, which is a beneficial upgrade since, in the previous model, this feature had to be unlocked manually by upgrading the software.

AutoChart Live will allow the angler to paint the depth contours on the fish finder as they drive the boat.

The angler will also be able to create maps when there are none available and can build better detail wherever needed.

Additionally, with the Humminbird HELIX 5 CHIRP SI GPS G2, you can utilize its SmartStrike mapping cards.

These are maps with a special interface that will highlight spots that likely have schools of fish, based on the inputs you selected.

For instance, you can choose the season, the water body type, the weather conditions presently, and the target species.

The fish finder will then crunch the data for you and highlight all the possible fish-holding spots in a magenta color.

This makes it significantly easier to find and catch fish.

  • Recording

You get about eight hours of recording on the finder, and after that, you get a Zero Lines card.

Another upgraded feature in this model is the Bottom Hardness Later.

When you map with the AutoChart Live, you can now record the hardness reading too and then display it as its very own layer on the map.

This feature is helpful when you need to display the transitions from mud to a harder bottom, which are known spots that attract fishes.

If that’s not enough, you can take advantage of the Vegetation Layer feature of the Humminbird HELIX 5 CHIRP SI GPS G2, too.

You can use this new and helpful feature by recording along with the AutoChart Live.

With this, you can record any vegetation in the water, which can be displayed on the map as a layer of its own.

It is helpful because you can see the points, turns, cuts, and holes in the weed beds while you are fishing.

Another significant upgrade to the Humminbird Helix Fish Finder is the LakeMaster PLUS, which are special map chips equipped with aerial and satellite imagery.

They are capable of displaying multiple styles of layers.

This particular feature is highly useful to see the shoreline structure and vegetation without the need to drive down the boat to the desired spot.


  • Improved keypad UI
  • Easy mapping and recording
  • Easily accessible buttons
  • Side and down imaging capabilities


  • Limited GPS capabilities

2. Humminbird HELIX 5 SI GPS

Our second fish finder is the Humminbird HELIX 5 SI GPS, which also comes with the highly efficient and popular SI or Side Imaging sonar technology.

This excellent technology will provide the angler with a complete view of their boat surroundings, giving them a better idea of their surroundings.


Evaluating this fish finder, here are the things we learned from the product that we wish to share with you:

  • Imaging

This fish finder from Humminbird is a complete unit that comes along with a dual-beam sonar, DI, and a switch-fire that will provide the angler with an array of different monitoring forms. There are also visible graphics that the angler can choose from.

  • Longevity

The folks at Humminbird have ensured that the HELIX 5 SI GPS is a device that will last you for years with the fear that this model will get outdated.

The company constantly rolls out software upgrades, and these updates ensure that your model is at par with all of their other models in the same line featuring new and innovative technology.

  • Mapping

The HELIX 5 SI GPS finder’s navigation feature has Unimap, which works right away the minute you take it out of the box.

It has been preloaded with a ton of detailed colored charts of all the major rivers, inland lakes, and coastlines in the USA.

The Humminbird HELIX 5 SI GPS also comes with a 250 colored five-inch screen, which delivers an exceptional resolution of 800 x 480 pixels for a high-quality, top-notch resolution.

This five-inch screen, along with the beautiful 800 x 480-pixel resolution do a great job together and complements each other well to provide the angler with clearer looking visual of everything occurring right below the boat.

  • Frequency

One of the major benefits of this device is that it has three ultra-powerful sonar frequencies that work together so that the angler can fine-tune the transducer.

That, in turn, helps the angler achieve results in spectacular and crispier details all at a level deeper than most of the other fish finders on the market.

  • Power

If that’s not enough, the HELIX 5 SI GPS has 500 watts of power, which ensures that the angler will have all the necessary information to capture fish located even as deep as 1500 feet.

The company claims that this fish finder is also capable of going down deeper than that.


  • Available at an attractive price point
  • High-resolution display
  • Big screen
  • Easily mountable


  • Doesn't come loaded with maps of European waters

3. Humminbird HELIX 7 CHIRP MDI

The Humminbird HELIX 7 CHIRP MDI is quite similar compared to the other fish finders in the same series.

However, the company has added a bunch of new upgrades and features that make this fish finder a great option.


As one of the top fish finder models that caught our attention, here are some the key features of HELIX 7 CHIRP MDI:

  • Imaging and Display

MDI, which stands for MEGA Down Imaging, which is a dedicated MEGA DI transducer that provides a far clearer image of the structure and an enhanced separation of the fish.

The finder also comes with a massive seven-inch screen with a color TFT display that has 800H x 480V resolution.

The unit also features Dual Spectrum CHIRP Sonar, a new upgrade that is pushed out in the HELIX 7 series.

These elements are “low q”, which is another fancier way of telling that the unit is “true CHIRP” that comes with a wide resonant frequency band.

To put it in simpler words, it offers better 2D sonar experience, fish arches, and target separation.

The HELIX 7 CHIRP MDI also comes with SwitchFire Sonar. This setting will control the way the sonar looks on the screen and to boost the sonar returns when the conditions of the water call for it.

  • Bluetooth Technology

What we like about the HELIX 7 CHIRP MDI is that it comes with in-built Bluetooth that allows the device to pair with your smartphone or tablet.

Upon successfully pairing the two devices, you will get message notifications on the fish finder and can control it with the RC2 remote.

You can update your fishfinder wirelessly through the FishSmart app.

  • Ethernet

What’s particularly interesting about this fish finder is that it features Ethernet networking.

Any model from this brand with G3N comes with an ethernet port on the back of the unit. You will have to buy the dongle separately, though.

This fish finder is capable of displaying 360 imaging data as an ethernet accessory. This 360-imaging compatibility is a secret weapon of most experienced anglers.

  • Mapping and Recording

The Humminbird HELIX 7 CHIRP MDI also comes with AutoChart Live, which will let the angler self-map waters that are uncharted.

As the angler drives their boat, the depth lines are automatically drawn on the screen.

It will show you important depth changes, bottom hardness, structure, and vegetation overlays that could be ideal fishing spots.

The device comes with storage for roughly eight hours of recordings, which you can expand if you use the AutoChart Zero Lines card.

This model also has LakeMaster and LakeMaster PLUS. As mentioned earlier, these are the standard types of mapping cards for this brand.

They simply display the aerial photos and satellite imagery of the land that surrounds the bodies of water.

Lastly, the Humminbird HELIX 7 CHIRP MDI has SmartStrike mapping cards, which are cards quite similar to the standard regional LakeMaster mapping card, but they have more SmartStrike data.


  • MEGA Imaging
  • Features Real CHIRP
  • Comes with Bluetooth capability
  • Comes with an ethernet port


  • GPS tends to glitch occasionally

4. Humminbird HELIX 7 CHIRP MSI

Given the product name, you would think that we are reviewing the same product as we did earlier.

However, this fish finder has MSI, MEGA Side Imaging, instead of MDI.


While the device is plastic, it does have a glass enclosure to keep it safe from the water and has a lot to offer, including:

  • Imaging and Display

The intense power and great detail provided by the MEGA Side Imaging is now available in this upgraded HELIX 7 model.

It is capable of getting the angler a minimum of 100 feet of coverage on either side of the boat.

Like the previous model we reviewed, the Humminbird HELIX 7 CHIRP MSI also comes has a seven-inch display with a resolution of 800 x 480 and shows 256 colors.

There is an LED backlight, too, which makes the images easier to see.

The display also works well under harsh and bright sunlight, ensuring you can make use of the device on the water all day long.

  • GPS

The device comes with GPS capabilities. With this, you can track your speed and location along with the general depths around the area.

It allows you to set routes and waypoints that will be helpful if the angler is out all day and could get possibly get lost.

It will also let you program a maximum of 45 routes and a whopping 4,500 waypoints.

  • Power

The Humminbird HELIX 7 CHIRP MSI is quite powerful, too, since it can transmit power of 500W and 4,000W from peak to peak.

It has an impressive depth of 1,500 feet for 2D images and about 100 feet for side imaging.

The similarities between this and the previous model we reviewed continue since this also features an amazing memory, SwitchFire, and a true CHIRP.

All the images that you see on its screen will be not only phenomenally clear but also in real-time all through your journey.


  • Impressive depth
  • Large screen
  • GPS capabilities


  • Built-in maps lack detail

5. Humminbird PIRANHAMAX 4 DI

The last fish finder we will review is slightly different since it does not belong to the HELIX variant.

It is available at an extremely reasonable price tag.

As such, it is one of the brand's top-rated, popular, and most budget-friendly fish finders designed for anglers of different skill levels.


The Humminbird PIRANHAMAX 4 DI is an excellent device which brings in all the exceptional qualities of a high-end fish finder, such as:

  • Design

Unlike the previous fish finders we reviewed, the design of this one is slightly different; it has a vertical design.

It features a 4.3-inch 256 color display and a display picture matrix of 272H x 480V.

Additionally, the Humminbird PIRANHAMAX 4 DI has a sonar coverage of 28° and 16°at -10dB.

Just like the rest, though, you can mount this fish finder easily, and you can adjust the tilt and swivel mount quickly for your viewing.

  • Sonar Technology

The Humminbird PIRANHAMAX 4 DI comes with Down-Imaging sonar technology and Dual-Beam PLUS.

Together, they offer the angler spectacular and accurate sonar returns about all that is occurring right under their boat.

When an angler is on the water sailing through it, countless things will need their focus, and for that, this fish finder has an audible alarm that will alert them of any fish or depth to ensure they are completely aware of what is going on below the boat.

If the finder does detect any fish in the water, its built-in alarm will begin to ring. Likewise, the alarm goes off if it feels the angler is sailing towards a shallow spot.

  • Fish-ID

You will enjoy the Humminbird PIRANHAMAX 4 DI fish finder’s fantastic Fish-ID function, which will scan the sonar frequency and give you the proper position of the fish.

This function is particularly beneficial when the fish species are close to an object or hiding under a plant.

  • Ease of Use

Another great thing about the Humminbird PIRANHAMAX 4 DI is that it comes with many advanced features that you would typically find in high-end fishfinder models.

The overall operation and the interface are quite user-friendly. The screen generates easy-to-read sonar signals and can zoom in or out to analyze the findings further.

With the Humminbird PIRANHAMAX 4 DI you can be assured that it will maximize the time you spend on the water.

It will assess your surroundings properly and identify fish species efficiently and as quickly as possible.

This fish finder comes with everything a new angler is looking for, like delivering exceptional graphical results and accurate bottom and depth tracking.

All of those together do a great job of enhancing your overall fishing experience.
