XM 9 HW MSI T Transducer

Humminbird XM 9 HW MSI T: The High-Performance Engine for Advanced Underwater Imaging

For serious anglers who demand the highest level of detail and power from their electronics, the Humminbird XM 9 HW MSI T transducer is the essential hardware link to the underwater world. Engineered specifically for Humminbird's premier HELIX G3N and G4N series fish finders, this transom-mount transducer unlocks the full suite of MEGA Imaging+ and Dual Spectrum CHIRP sonar, delivering unprecedented clarity and fish-finding capability.

Core Features at a Glance:

• Flagship Imaging Technologies: Combines MEGA Side Imaging+, MEGA Down Imaging+, and High-Wide (HW) Dual Spectrum CHIRP 2D sonar into a single, high-performance unit.
   
• Next-Level Detail: MEGA Imaging+ pushes sonar into the megahertz frequency, producing images with up to 20% more detail than standard MEGA Imaging, allowing you to distinguish fish from structure with photographic clarity.
   
• Superior 2D Sonar: High-Wide Dual Spectrum CHIRP provides crisp, clean fish arches, exceptional target separation, and the flexibility of selectable beam widths.
   
• Robust Construction: Features a durable composite design and a heavy-duty, all-metal transom mounting bracket built to withstand the rigors of high-speed running and harsh marine environments.
   
• Integrated Temperature Sensor: Provides fast and accurate surface water temperature readings directly to your Humminbird display, helping you pinpoint thermal breaks where fish congregate.
   
• Seamless Integration: A 20-foot cable and included hardware ensure a secure installation and reliable connection to compatible Humminbird units.
   

A Technical Deep Dive into the Sonar Capabilities

The XM 9 HW MSI T is more than just a transducer; it's a multi-frequency sonar powerhouse designed to give a complete picture of the water column.

MEGA Side Imaging+ (MSI+)

This technology is a revelation for scanning vast areas to find productive water. MEGA Side Imaging+ provides a razor-sharp, 180-degree view out to 200 feet on both sides of your boat. The megahertz frequency reveals individual fish, submerged logs, rock piles, and even subtle changes in bottom composition with detail that was previously unimaginable. It's the ultimate tool for dissecting structure and locating fish away from the boat.

• MEGA SI+ Frequency: 1075-1150 kHz (Range: 400 ft side-to-side)
• 800 kHz Side Imaging: 790-850 kHz (Range: 250 ft side-to-side)
• 455 kHz Side Imaging: 440-500 kHz (Range: 800 ft side-to-side)
   

MEGA Down Imaging+ (MDI+)

For a precise, top-down view of what’s happening directly below your keel, MEGA Down Imaging+ offers unparalleled clarity. It resolves the underwater world into picture-like images, allowing you to see individual branches on a submerged tree, identify fish suspended within cover, and easily differentiate between bait and gamefish. MDI+ takes the guesswork out of interpreting traditional sonar returns.

• MEGA DI+ Frequency: 1075-1150 kHz (Max Depth: 200 ft)
• 800 kHz Down Imaging: 790-850 kHz (Max Depth: 125 ft)
• 455 kHz Down Imaging: 440-500 kHz (Max Depth: 400 ft)
   

High-Wide (HW) Dual Spectrum CHIRP 2D Sonar

This is the evolution of traditional 2D sonar. Instead of transmitting on a single frequency, Dual Spectrum CHIRP sweeps across a range of high frequencies, resulting in significantly more data. This translates to stronger, better-defined fish arches, superior target separation (letting you see a fish sitting tight to the bottom), and reduced noise for a cleaner display.

• Wide Mode (140-200 kHz): Uses a wide cone angle (42°) for maximum search area, perfect for locating fish in the upper water column or when searching new water.
• Narrow Mode (180-240 kHz): Uses a tight cone angle (25°) for maximum detail and bottom definition, ideal for picking out individual fish from structure or for precise vertical jigging presentations.
• Full Mode (150-220kHz): Blends the best of both, offering a comprehensive view with excellent target separation.
   

Primary Compatible Models & Usage

The Humminbird XM 9 HW MSI T is the standard, factory-supplied transducer for a specific range of high-performance Humminbird units. It is engineered to provide the power and receive the signals necessary to enable the "MEGA+" capabilities of these larger-screen models.

This transducer is the correct and standard equipment for the following models:

• HELIX 8 CHIRP MEGA SI+ GPS G3N & G4N
• HELIX 9 CHIRP MEGA SI+ GPS G3N & G4N
• HELIX 10 CHIRP MEGA SI+ GPS G3N & G4N
• HELIX 12 CHIRP MEGA SI+ GPS G3N & G4N
• HELIX 15 CHIRP MEGA SI+ GPS G4N

Important Note: This model is distinct from the XNT 9 HW MSI 150 T transducer, which is designed for the HELIX 7 series. The XM 9 HW MSI T is specifically matched to the more powerful processing and display capabilities of the HELIX 8, 9, 10, 12, and 15 models, ensuring they perform at their peak factory specifications. Using the correct transducer is critical for achieving the advertised image quality and depth capabilities.
