The Humminbird Ice Helix 7 CHIRP GPS G3 is an upgrade to Ice Helix 5. It’s also an upgrade to the older G2 unit, offering a few new improvements designed to make your ice fishing more effective. You can learn about these improvements in this Humminbird Ice Helix 7 review. Here, we’ll cover all its features from sonar to navigation capabilities.
Humminbird Ice Helix 7 Features
First of all, the Humminbird Ice Helix 7 fish finder comes with an ultra-bright full color display. It measures 7 inches in diagonal. It’s easily readable, even if you’re viewing at a distance. The screen also supports a dual panel mode, which allows viewing both the flasher and 2D sonar data simultaneously.
The display also features keypad control with clearly marked buttons for navigation. It offers simple control of the unit’s menus and settings.
One feature that makes the interface of this fish finder very intuitive is the X-Press Menu System. It allows you to pick your most used applications for displaying on the homepage. This would allow accessing these applications a one-step process.
This fish finder doesn’t have any Ethernet or NMEA support, which means that the system is not networkable. However, there’s one micro SD card slot. You can use it for backing up your waypoints and saved sonar data, such as screenshots and recordings. On top of that, it can be used for upgrading the software and charts.
Since this unit is designed for ice fishing, it is a portable fish finder that comes with a convenient carrying case. Inside, it fits the display and other fish finder accessories, which include the transducer with the transducer cable, battery and charger. This makes it convenient to take this fish system anywhere you go. And to protect the ice fishing fish finder during transportation, the carrying case comes with soft sides.
The included battery features 9 amp hours. However, when you’re using a lower brightness setting, the battery can last as long as 24 hours. This should be plenty enough for at least a full day of fishing before needing to recharge the battery.
The Humminbird Ice Helix 7 CHIRP GPS G3 fish finder comes with a transducer that’s designed for ice fishing. It supports two modes, which are CHIRP sonar and flasher.
Its Dual Spectrum CHIRP transmits and receives pings at 50/83/200kHz frequency. The sonar can also be modulated in the 130-250kHz frequency range.
Depending on which frequency you use, the sonar will have a beamwidth of 15 or 21 degrees. Both provide high resolution returns with target separation up 1.5 inches. You’ll be able to see on the screen individual fish, bait and structure.
The unit also offers good depth capability with the sonar being able to reach up to 400 feet. This is plenty enough sonar reach for most ice fishing situations.
With a push of a button, the unit also allows you to choose how you want the sonar returns to be displayed. You can switch between the Clear Mode and the Max mode with the first one removing unnecessary clutter, so you can find bigger targets and the second one showing maximum detail.
This ice fishing fish finder also features a 1024-segment flasher. Instead of the traditional 2D sonar graph, this mode displays sonar returns on a circular depth scale. Also, since it’s a latency-free function, all the sonar returns are displayed in real time.
The unit also offers an interference rejection function, which works in both sonar and flasher modes. With six settings, you can adjust it to get the clearest sonar signal. If you’re fishing with other fish finders or other devices in the area, the interference rejection function would filter out any noise and keep the competing sonar signals from cluttering your screen.
Another thing that’s worth mentioning is that this fish finder can be used year round. The unit works with all compatible Helix 7 CHIRP GPS transducers. So, to fish from your boat during summer, just install the new transducer on your boat and switch to the Open Water mode.
The Humminbird Ice Helix 7 also comes with a built-in GPS system. Its high-precision GPS module allows tracking your boat’s position on the included maps.
The unit comes preloaded with Humminbird Basemap, which features a high level of detail. It covers more than 10,000 U.S. lakes and provides a view of the underwater terrain and various points of interest. It shows buoys, daymarkers, hazards, depth markers and many other marked points. All of this can help you navigate with ease and confidence.
If you would like to have more advanced cartography, the availability of the micro SD card slot makes the unit compatible with the Navionics+, Navionics Platinum +, LakeMaster Plus and other more detailed charts.
Using the GPS system of this fish finder, you can also save waypoints, routes and tracks. This can be useful for marking your favorite fishing spots or other locations that you would like to go back to again. It can also be useful for saving routes or tracks to navigate around different hazards, which would help you safely navigate to any location and back.
Humminbird Ice Helix 7 Pros and Cons
The Humminbird Ice Helix 7 offers the perfect combination of ice fishing flasher, 2D sonar and chartplotting capabilities. It offers powerful CHIRP sonar performance, an advanced ice fishing flasher mode and a highly detailed Basemap. This can help you find the best fishing spots and make the fishing experience more fun and effective. Moreover, if you buy another compatible transducer, you could also be using this fish finder year round.
