Revolutionary MEGA Imaging Technology
MEGA Side Imaging - See 125 Feet on Each Side
MEGA Side Imaging technology transforms underwater exploration by providing crystal-clear viewing out to 125 feet on either side of your boat. This advanced sonar system delivers up to 3x more detail than standard Side Imaging, revealing fish, structure, and bottom composition with unprecedented clarity. Whether you're searching for schools of baitfish, fallen trees, rock piles, or other fish-holding structure, MEGA Side Imaging shows you exactly where to cast.
MEGA Down Imaging - Pinpoint Precision Below
The MEGA Down Imaging system provides unmatched underwater clarity with coverage down to 125 feet directly below your boat. This high-frequency imaging technology delivers incredibly detailed views of bottom structure, vegetation, and fish, allowing you to distinguish between species and identify the most productive fishing spots with confidence.
Dual Spectrum CHIRP Sonar Technology
Before you cast, know exactly what's down there with Dual Spectrum CHIRP sonar technology. Powered by Humminbird's proprietary Low-Q CHIRP transducer, this advanced sonar system provides highly detailed fish arches and crystal-clear views of fish-holding structure and bottom composition.
The system offers two distinct search modes:
- Wide Mode (140-200 kHz): Maximum coverage for scanning large areas efficiently
- Narrow Mode (180-240 kHz): Focused beam for examining fine details and individual targets
- Full Mode (150-220 kHz): Comprehensive coverage combining both approaches
CHIRP technology covers frequency ranges from 83/200 kHz (75-155/130-250 kHz), providing superior target separation and fish identification compared to traditional single-frequency sonar.
Built-in GPS and Advanced Chartplotting
Precision GPS Navigation
The integrated precision GPS system provides accurate position fixing for better waypoint marking and boat positioning. Store up to 2,750 waypoints to mark your most productive fishing spots, structures, and navigation hazards with pinpoint accuracy.

Frequently Asked Questions
What makes MEGA imaging different from standard imaging?
MEGA imaging technology provides up to 3x more detail than standard Side and Down Imaging systems. Operating at higher frequencies (1075-1150 kHz), MEGA imaging delivers crystal-clear views of underwater structure, fish, and bottom composition with unprecedented clarity and resolution.
How does CHIRP sonar improve fish detection?
CHIRP (Compressed High Intensity Radar Pulse) technology sweeps through a range of frequencies rather than using a single frequency. This provides better target separation, more detailed fish arches, and clearer distinction between fish and structure compared to traditional sonar.
Can I create my own maps with this unit?
Yes, AutoChart Live technology allows you to create real-time maps as you fish. The system maps depth contours, bottom hardness, and vegetation automatically, with 8 hours of built-in recording time and compatibility with AutoChart Zero Line SD cards for unlimited mapping capacity.
What transducer is included with the HELIX 7?
The unit includes the XNT-9-HW-MSI-150-T transducer, which provides MEGA Side Imaging, MEGA Down Imaging, and Dual Spectrum CHIRP sonar capabilities in a single transom-mount housing.
Is the HELIX 7 compatible with trolling motors?
Yes, the HELIX 7 is compatible with Minn Kota US2 sonar-enabled trolling motors and can also work with Minn Kota units featuring built-in MEGA Down Imaging transducers for integrated boat control and sonar operation.
What chart options are available for this unit?
The HELIX 7 supports LakeMaster and CoastMaster charts from Humminbird, as well as Navionics Gold, Platinum+, and HotMaps. SmartStrike cards are also compatible, providing advanced fish location algorithms based on seasonal patterns and lake data.
