Humminbird Helix 7 Features

In this section, we’ll take a closer look at what the Helix 7 Humminbird has to offer.

Sonar and Cartography:


The Humminbird Helix 7 Chirp Si GPS G2 has a simple logic to its functionality. It sees the fish, and lets you know so you can catch them. And it won’t just work for one or two lures. With this device, the sky is your limit.

This unit works a lot like a tackle box. It contains several different tools, each designed to do its part in helping you land an ideal catch. CHIRP has a specific job of its own, finding fish that the other SONAR imaging of this device cannot.

Humminbird Basemap:

This version of the fishfinder boosts the standard basemap, allowing it to provide greater detail and a better fishing experience.

The Humminbird Helix 7 Sonar GPS uses the newest data from LakeMaster and other trusted sources. These super-accurate maps deliver depth contours, navigation aid, and points-of-interest; all of which give you a complete view of the underwater terrain and everything around you.

Autochart Live:

The Humminbird Helix 7 Di GDP model will give you AutoChart Live views. This will give you the ability to create vividly detailed maps of your most frequented fishing spots in real-time.

Depth isn’t all that this device is good for. Humminbird Helix 7 Mega SI also shows you depth contours, debris, vegetation, and bottom hardness. Every compatible unit of the Humminbird has 8 hours of recording time.


If you hate wasting time searching for fish, this device will be a lifesaver. The Humminbird SmartStrike feature helps find fish instantly, so you can focus on catching them. Just set your desired parameters and the results will appear on the screen right away.

Mega Down and Side Imaging:

The Humminbird Helix 7 SI/GPS Combo gives you a wider view of the water on all sides. The Side Imaging sonar uses two precise beams aimed perpendicular to the vessel’s path to take acoustic readings of the surroundings up to 400 feet left and right from your location. These images are all collected to create a very detailed view of the bottom of the water body.

Similarly, the down imaging uses a thin high-frequency beam that takes images of fish, vegetation, debris, and underwater structures. These images are so clear you can even see the fish and identify the species and different parts.

The down images are shown vertically, with the latest data appearing on the right side of the screen. You can use it in both saltwater and freshwater for depths ranging up to 400 feet. If you are targeting a certain kind of fish, it will help you differentiate between bait fish and game fish, and different species.

Between the Down Imaging and CHIRP Digital Sonar, you can identify vegetation, obstacles, and structures and discover the fish hiding within.

Other Features of the Hummingbird Fish Finder Helix 7:

Next-level imaging isn’t the only thing that sets this fishfinder apart from other models. Here’s what else will help you out on the water.

Switchfire and Dual Beam:

Based on their use of sonar innovation, the SwitchFire puts fishers in absolute control of how their sonar images appear to them. It has 2 separate display modes, and you can adjust the display settings based on fishing conditions.

It allows you to add or remove detail; calibrate for water depth, temperature, and turbulence, and toggle lure presentations with the press of a button. SwitchFire gives regular 2D fish finding a massive boost, and you’ll never go back to the old way.

Precision GPS:

The Helix 7 CHIRP SI GPS G2 provides incomparable GPS technology from its very first use. Most Humminbird fishfinders have the powerful Precision GPS/WAAS receiver built right in and offer quick changes in position without any extra trouble.

Slender Profile Display:

No one likes bulky gadgets, especially people with lots of other fishing gear. But you won’t have to worry about it with this fishfinder. Any Humminbird Helix 7 DI review will tell you how sleek and slim the display is.

The integrated screen and frame of this device will give you a single, continuous surface. Furthermore, the display is surrounded by an ultra-slim bezel that minimizes space and adds to a cool and modern aesthetic.

Super Bright LCD Display:

The Humminbird Helix 7 has a 7-inch display, which strikes the perfect balance between compactness and clearly showing you all the details captured by the imaging.

The resolution is 800-by-480 pixels and shows 256 colors that help you find the perfect place to fish and see what’s going on underwater. There is also an LED backlight that makes the images clearer and easier to see, even in intense sunlight.

Improved Memory:

As any Humminbird Helix 7 DI GPS review will tell you, it has double the RAM. This is quite necessary as all the data it captures needs room for storage. Because the Helix 7 commonly shows side-by-side images, limited RAM can create lots of issues.

The increased RAM will also keep the images clear and in real-time. There are few or no lags, so there’s no chance of missing any fish darting around you.

The CHIRP sonar adds to this and helps you see fish, debris, obstacles, and underwater structures around you. At the same time, it is easy to mount or carry with you in between uses. The unique features make it a must-have for new and professional anglers everywhere.
