Humminbird invented side imaging sonar and still builds the best imaging units on the market. MEGA Imaging — their 1.2 MHz ultra-high-frequency sonar — produces images so detailed you can identify individual branches on submerged trees. This guide covers every major Humminbird series and our recommended model in each category.

1. Humminbird HELIX 12 CHIRP MEGA SI+ GPS G4N — Best Overall
Humminbird HELIX 12 CHIRP MEGA SI+ GPS G4N
What We Like
- MEGA Side Imaging+, MEGA Down Imaging+, 12" screen, Ethernet networking for MEGA 360 compatibility, AutoChart Live, built-in Bluetooth, Wi-Fi for Humminbird app
What Could Improve
- Over $1,000 price point, MEGA transducer sold separately in some bundles
The HELIX 12 G4N is the gold standard for freshwater structure fishing. MEGA Imaging+ at 1.2 MHz provides imaging quality that competitors simply cannot match — at any price. In our testing, we could identify individual pieces of structure (fallen trees, rock piles, dock posts) with more detail than any other sonar we have used. The G4N generation adds networking for MEGA 360 Imaging compatibility — the ability to see sonar in a full 360-degree sweep around the boat.
2. Humminbird HELIX 9 CHIRP MEGA SI GPS G4N — Best Mid-Range
Humminbird HELIX 9 CHIRP MEGA SI GPS G4N
What We Like
- 9" screen, full MEGA Side Imaging and Down Imaging, Ethernet networking, G4N generation includes improved GPS module
What Could Improve
- MEGA transducer must be purchased separately (adds $150–$200 to cost)
The HELIX 9 G4N gives you MEGA imaging and networking at a price that stops short of four figures. If you are stepping up from a basic fish finder for the first time, this is the model that will genuinely change how you fish. The jump from standard down imaging to MEGA Side Imaging is not incremental — it is transformational.
3. Humminbird HELIX 7 CHIRP MEGA SI GPS G4 — Best Value Imaging
Humminbird HELIX 7 CHIRP MEGA SI GPS G4
What We Like
- MEGA Side Imaging at $449 is an incredible value proposition, 7" screen, built-in GPS with Navionics+ maps
What Could Improve
- No Ethernet networking (cannot add MEGA 360), smaller screen limits split-view usability
The HELIX 7 G4 brings MEGA Imaging technology down to $449 — a price point where competitors are still using standard side imaging frequencies. For budget-conscious anglers who want the best imaging available, this is the unit to buy. The absence of Ethernet networking means no MEGA 360 upgrade path, but the core sonar quality is identical to the HELIX 12.
4. Humminbird APEX 19 MXHS — Professional Tournament Grade
Humminbird APEX 19 MXHS
What We Like
- 19" anti-glare display, MEGA Live Active Imaging 3-in-1 transducer included, the best imaging sonar available at any price, designed for tournament and professional use
What Could Improve
- $3,499 price is prohibitive for most anglers, requires serious electrical system planning
The APEX 19 MXHS is for professional tournament anglers and those who demand the absolute best regardless of cost. The 19" display shows split sonar, charts, and MEGA Live simultaneously without compromise. The MEGA Live Active Imaging 3-in-1 transducer is included — that alone is a $599 value. This is not a recreational purchase; it is a competitive tool.
5. Humminbird HELIX 5 CHIRP GPS G3 — Best Budget Humminbird
Humminbird HELIX 5 CHIRP GPS G3
What We Like
- 5" display (largest in budget class), Dual Spectrum CHIRP, proven Humminbird reliability, excellent shallow-water performance
What Could Improve
- No side imaging at this price, no MEGA technology, no networking
The HELIX 5 G3 is the best entry point into the Humminbird ecosystem. No side imaging at this price, but the 5" screen is the largest in the sub-$200 bracket and Dual Spectrum CHIRP delivers outstanding fish arch detail in shallow water. A great starter unit before stepping up to MEGA imaging.
Understanding Humminbird MEGA Imaging
Standard Side Imaging operates at 455/800 kHz. MEGA Side Imaging operates at 1.2 MHz — a significantly higher frequency that produces sharper, more detailed images. In testing, MEGA Imaging shows individual branches on submerged timber where standard side imaging shows only a vague blob. If structure fishing is your primary technique, MEGA imaging is worth every penny of the premium.
