Humminbird Helix 7 Review and  Buying Guide

Fishing aficionados know the difference a quality fish finder can make in ensuring a successful expedition. Not only should it help you locate moving fishes, but it should also help you detect obstructions in the water, as well as map out your favorite fishing spots.

One of the most popular and most complete brands you will find in the market is Humminbird. Throughout its 40 years in the industry, this company has constantly introduced technological innovations that help make angling more efficient and enjoyable. I think it is safe to say that they have held true to their promise of providing their customers with difference-making days out on their fishing expeditions.

To introduce you more to the brand, I will be discussing some variations of the Humminbird Helix 7 fish finder. If you are interested in buying one of these devices, I invite you to read along and get to know more about this product.

Humminbird Helix 7 410310-1 SI / GPS G2 Fish Finder

If you are looking for a state-of-the-art fish finder, look no further than the Humminbird Helix 7 G2 combo. Armed with the highest level of CHIRP technology and 256-color display screen. This allows you to see fish underwater with incredible clarity and move to spots with the highest catch rates.

The Helix 7 G2 combo also comes with a built-in GPS and a slew of other similar features. This device has the most accurate mapping system I have seen as it has over 10,000 locations programmed into it. It also allows you to map and save your favorite fishing spots for easy access.


  • Duel Beam settings allow you to be effective in both shallow and deep waters
  • Switch Fire Sonar helps you pinpoint the location of fish and other obstructions
  • CHIRP technology provides clear images
  • Maximum depth of 1500 feet
  • GPS feature guide you to map different bodies of water

Overall, this is an incredible piece of machinery. This particular device is suited for individuals who are extremely passionate about angling and go on fishing trips regularly. Since it comes with a very expensive price tag, unless you are interested in fishing, I would not suggest you go near the Humminbird Helix 7 G2. However, as long as we are simply focusing on the function, this is one of the most complete models on the market.


  • Complete and provides you with a wide range of functions
  • Fairly easy to use
  • Easy to see details on the screen
  • GPS functions keep you from getting lost


  • Extremely pricey
  • Does not come with a cover


Humminbird Helix 7 410280-1 DI G2 Fish Finder

Compared to the G2 model, the Helix 7 DI G2 fish finder may seem like a bit of a downgrade, but it still provides very useful benefits. Like the majority of Humminbird’s products, this device also comes with CHIRP technology, which provides you with solid imagery. The main use of this gadget is finding fish, and it does its job quite well.

It comes with a solid transducer that easily detects SONAR waves in the water from the fish and other possible obstructions. It also collects pertinent information such as temperature and water depth, which are major factors when you go fishing.


  • CHIRP technology provides accurate images of the situation underwater
  • Maximum depth reach of 600 feet
  • Solid transducer which helps you compile important details
  • Comes with different mounts for convenience

The biggest disappointment of the Helix 7 DI G2 fish finder is the absence of a GPS and mapping system. Considering you will have to pay almost $400 seems unreasonable, but the benefits that it gives can justify the price. At the very least, it is a solid fish finder that helps you accurately locate marine life under water.


  • 7-inch screen is big enough to read from afar
  • LED backlight allows you to view the screen even in extreme conditions
  • Multiple settings to choose from depending on the situation


  • No GPS or mapping system
  • Heavier compared to other options
  • Does not come with a unit cover


Humminbird Helix 7 410300-1 DI/GPS G2 Fish Finder

Among the options on this list, the Helix 7 410300-1 fish finder may not be the most complete or the least expensive, but in my opinion, it is the most affordable. Actually, this is quite similar to the Helix 7 G2 model, only with an added GPS system. It includes location settings with 2500 pre-installed waypoints, as well as 50 routes you can choose from. This is a feature I enjoy using because it allows me to remember the fishing spots I have found success in so I can go back in the future.

This particular option also comes equipped with a strong down-imaging SONAR system so you can see exactly what is underneath the boat. The maximum deepness of 600 feet was a little unsatisfactory, but at least the manufacturers provide you with a solution by increasing the total depth covered if you buy an external transducer.


  • CHIRP down imaging gives you clear pictures on the screen
  • GPS with pre-installed destinations and routes
  • 16-bit color display
  • SD card slot for additional software
  • Traditional 2D SONAR with dual options setting

Like I have said, the Humminbird Helix 7 DI/GPS G2 fish finder provides you incredible value for money. If you are looking for a semi-complete option with above-average features, this should be one of the top options you consider.


  • Good value for money
  • Strong down imaging system
  • Can be effectively used for down-dropping or ice fishing expeditions
  • Comes with an improved interface and operating system


  • No connectivity with external GPS or navigation systems
  • Only has one SD card slot


Humminbird Helix 7 410290-1 GPS G2 Fish Finder

The final Helix 7 version we will be discussing in this article is the 410290-1 GPS G2 fish finder. In terms of screen resolution, this particular option is eerily similar to the 410310-1 model that we discussed earlier. It has the same 256-color display and 800H by 480V specifications. Similarly, it also has a built-in GPS with Anima cartography that helps you maneuver around bodies of water and remember fishing spots you have been to before. The main difference here that there is not many pre-programmed locations to choose from.

The SONAR system in this model is also pretty strong. It has a maximum depth capacity of 1500 feet, which can be increased to 2500 feet if you purchase an external transducer. If you ask me, the initial ability is good enough. The dual beam ability also gives you the freedom to customize the settings according to your preference. This can either be used to shallow or deep waters, depending on your situation.


  • CHIRP dual beam technology
  • GPS with Anima cartography
  • Strong 256-color display clarity and precise images
  • Ability to save waypoints on your trips
  • Auto Chart Live gives you ability to create maps of your favorite fishing spots

The Humminbird Helix 7 410290-1 G2 model’s price is quite similar to the 410280-1 one, but with the added GPS and enhanced image quality, this is a clear upgrade. However, what it lacks is a strong SI / DI system, which high models possess. Overall, this is still a valuable option to buy.


  • Practical location features
  • Clear screen which is big enough at 7-inch width
  • Easy to use
  • SD card slot can be used to add software


  • Limited side image or down image features
  • Does not come with a cover
  • Only 1 SD card slot is available


Factors to Consider When Buying a Fish Finder


Side Imaging or Down Imaging

Both of these options are innovations by Humminbird, and each answer a specific need. Side imaging is more applicable if you want to scope out the distance in a lake or sea. It allows you to see the exact location of where certain things area. On the other hand, down imaging is more useful if you have already spotted a specific area and want to explore it some more. As the name suggests, this helps you search through the depth in a body of water. While side imaging provides you with a clearer image, down imaging is more affordable to buy, so it all depends on your need.


Screen Resolution

The resolution of the screen is an important factor to have, and generally speaking, Humminbird models have an exceptional quality. I think the main consideration here is if you need the top of the line models or not. More high-end models come with anti-glare features or very detail-oriented images.



Humminbird is known to be a very expensive brand, so when deciding which variation of the Helix 7 you want, budget plays a big role. Are you willing to spend a few hundred dollars on extensive SONAR 3D technology, or are you fine with basic features? Do you need a built-in GPS? These are just some questions you should ask yourself when deliberating on the amount of money you are willing to spend for this purchase.



All these four Humminbird Helix 7 variants are very similar to each other. Generally speaking, the only difference between each is a few details here and there. That is why it makes the decision to choose the best one incredibly difficult to make.

However, if I had to choose which one I would recommend, I guess it would be the Humminbird Helix 7 410300 model. I believe it can provide you with all the basic features you need to increase the chances of a successful fishing expedition. It has a great GPS system, strong SONAR technology, and an affordable price, which will give you exceptional value for money. Take a look at this model to see if this is the right one for you.
