Humminbird Helix 5 Chirp GPS G3 Fish Finder Review
Key Takeaways
-
- Advanced Dual Beam CHIRP Sonar: The unit utilizes a modern CHIRP system that pulses across a range of frequencies (supporting both $83\text{ kHz}$ and $200\text{ kHz}$). This dual-beam tech provides vastly superior target separation, cleaner imaging, and reduced clutter compared to old-school, traditional 2D sonar.
- SwitchFire Technology: A highly practical toggle feature allows anglers to jump instantly between two screen modes:
- Clear Mode: Filters out water clutter, sediment, and minor noise to isolate and show only the largest, clearest fish targets.
- Max Mode: Displays raw, unfiltered sonar data down to the smallest detail, giving experienced anglers a complete picture of structure and baitfish.
- Impressive Depth Range: Straight out of the box with the included Transom XNT 920 T transducer, the system reads depths down to 1,500 feet. For deep-dropping or serious offshore work, upgrading to the optional Deep Water Transducer bumps its reading capability up to 2,500 feet.
- Built-in AutoChart Live: Rather than relying purely on pre-loaded regional data, the internal GPS software lets you map uncharted water in real time, building custom contour lines as you drive the boat.
- Massive Waypoint Storage: Functions as a highly capable digital fishing log, holding up to 2,750 individual waypoints, 47 distinct routes, and 50 tracking paths (with up to 50,000 track points per path) to pinpoint exact honey holes and flats structures.
- Form Factor & Limitations: Features a compact $5\text{-inch}$ high-resolution display ($800 \times 400\text{ pixels}$) with a bright 16-bit color LED setup. Note that while it uses premium CHIRP technology, this specific baseline unit does not include down imaging (DI) or side imaging (SI) capabilities.
For several years, the folks at Humminbird have been producing some of the very best fish-finding technology on the market, and the Humminbird Helix 5 Chirp GPS G3 Fish Finder is a perfect representation of the top-tier technology they bring to the table.
About as advanced a fishfinder as you will find on the market today, the Humminbird Helix 5 Chirp GPS G3 Fish Finder is relatively inexpensive (especially compared to some of the other less feature-rich but more expensive options) while still taking advantage of incredibly advanced technology throughout.
Featuring a game-changing sonar technology in the CHIRP Sonar system and taking advantage of Auto Chart Technology, this might be the last fish finder you ever purchase from here on out!

Highlighting the sonar technology “under the hood”
The major reason to get your hands on the Humminbird Helix 5 Chirp GPS G3
Fish Finder compared to all of the other fishfinding options available on the market is that of the advanced CHIRP Sonar built right into this unit.
Supporting both the 83 and 200 kHz frequencies, you are going to be able to modulate the pulse that’s generated by your transducer over a range of different frequencies – helping you to dial in the accuracy of the Humminbird Helix 5 Chirp GPS G3 Fish Finder while you are using it.
This will allow you to produce superior target separation, much better imaging with much less “noise,” advanced bottom lock, and much-improved depth capabilities compared to currently available options.
While the Humminbird Helix 5 Chirp GPS G3 Fish Finder does not include side imaging or down imaging technology, the CHIRP Sonar is more advanced than a traditional 2-D system. Utilizing the Dual Beam Plus technology, you can scan the water under your boat with both sonar beams simultaneously, painting a much more accurate picture with this system than you would have been able to with traditional 2-D sonar solutions.
You’re also going to be able to read the temperature of the water at varying depths effortlessly and reach 1500 feet in readings with the Humminbird Helix 5 Chirp GPS G3 Fish Finder right out of the box. There is also a Deep Water Transducer accessory available. When you pair it with your Humminbird Helix 5 Chirp GPS G3 Fish Finder, you can increase your depth reading capabilities by up to 2500 feet.
Selective Fish ID, Fish Alarm, Sonar Recording, and Switch Fire technology are all built into the Humminbird Helix 5 Chirp GPS G3 Fish Finder unit. Your Switch Fire will probably be the most frequently used and appreciated feature of the bunch. It allows you to quickly jump between “Clear” and “Max” modes, eliminating all of the clutter and noise on your fish-finding screen and instead providing you with information on only the biggest fish targets possible, allowing ALL sonar information to be presented so that you can pick and choose the fish you want to target.
Humminbird also offers top-tier innovations in the Circular Flasher, Bottom Lock, and Real-Time Sonar (RTS).
You’ll be provided with real-time information about the depths you are fishing in, including details regarding the true bottom and real-time feedback from your sonar system as it scans. When both systems are running in the background, you can track fish movements more effectively and efficiently!
Navigational features
Basic mapping features are included with every single fish-finding option available right now. Still, you’ll find incredibly advanced and detailed maps and charts provided with the Humminbird Helix 5 Chirp GPS G3 Fish Finder.
You’ll get incredibly in-depth information about contiguous US coastlines, inland lakes, and rivers, as well as 3-D details that allow you to better understand the topography you are getting into when you’re heading out to go fishing.
Planning, mapping, and charting technology also allow you to set different waypoints to better plan your day on the water. Because the system is intuitive and easy to use, you can also update your charts with “inside information” about the fish you are after on the fly.
You can track up to 2750 waypoints across 47 individual routes with 50 different tracks – and each track is available to hold up to 50,000 track points along the way. This might become the most useful fishing journal you’ve ever accessed, and it’s all thanks to the incredible navigational charts and Auto Chart Live technology baked right in.
Frequently Asked Questions

Final Thoughts
The Humminbird Helix 5 CHIRP GPS G3 punches well above its weight class by squeezing premium internal hardware into an entry-level, cost-conscious footprint.
While the lack of high-frequency side or down imaging might be a dealbreaker for structural tournament anglers, its combination of dual-beam CHIRP, real-time depth mapping, and heavy-duty waypoint logging makes it an incredibly reliable tool for small boats, kayaks, and budget-minded flats or lake fishermen.
It successfully bridges the gap between basic, low-cost depth finders and ultra-premium commercial marine electronics.
