Humminbird XTM-9-HW-MDI-T MEGA DI+ Dual Spectrum CHIRP Trolling Motor Transducer w/Temp f/HELIX® MEGA DI

Unlock Crystal-Clear Underwater Views with the XTM-9-HW-MDI-T Transducer

Imagine gliding across the water, your boat's trolling motor humming quietly as you zero in on schools of fish hidden beneath the surface. The Humminbird XTM-9-HW-MDI-T transducer transforms your HELIX fishfinder into a powerhouse of precision sonar imaging. Engineered specifically for trolling motor mounts, this rugged unit delivers MEGA Down Imaging+ alongside Dual Spectrum CHIRP sonar, giving you the edge to spot structure, baitfish, and trophy catches with unmatched detail.

What sets this transducer apart is its ability to paint a vivid picture of the underwater world. MEGA DI+ at 1.2 MHz (1075-1150 kHz) reaches depths up to 200 feet with hyper-detailed resolution, perfect for picking out subtle bottom contours or suspended gamefish in shallow bays. Pair it with Dual Spectrum CHIRP's versatile 150-220 kHz range, and you're scanning down to 1200 feet—full coverage for deep-water hunts or wide-area searches.

Key Specifications That Deliver Real-World Performance

Built tough for the demands of serious anglers, this 7-pin transducer features a composite housing that withstands rough waters, impacts from debris, and constant exposure to saltwater. The included 20-foot cable provides ample reach for clean routing, while stainless steel clamp rings ensure a secure fit on most trolling motors.

Every detail is optimized for reliability—from the integrated temp sensor that tracks water conditions in real-time to the power line noise filter that keeps your sonar readings clean and interference-free, even in busy boating areas.

Seamless Compatibility with HELIX Series Fishfinders

This transducer is a perfect match for HELIX 8, 9, 10, and 12 CHIRP G3N models equipped with MEGA DI and MEGA SI+ capabilities. It plugs right into the 7-pin connector, unlocking advanced imaging without needing adapters or extra hardware. Whether you're running a compact setup on a kayak or a full-featured console on your bass boat, it integrates effortlessly to elevate your fishfinding game.

Installation Made Simple for On-the-Water Success

Setting up the XTM-9-HW-MDI-T is straightforward for DIY enthusiasts. Start by selecting a smooth section on your trolling motor shaft, typically 12-18 inches below the waterline when deployed. Secure the transducer using the provided stainless clamp rings—tight but not overtightened to allow for vibration absorption. Route the cable along the motor arm, securing it with zip ties to avoid prop wash interference.

Pro tip: Align the transducer face parallel to the bottom for optimal Down Imaging. Test in shallow water first, adjusting for any air bubbles or cavitation. With its rugged design, it's ready for immediate use in freshwater or saltwater pursuits.

Why Anglers Trust This Transducer for Consistent Results

Crafted in the USA with a focus on durability, the XTM-9-HW-MDI-T stands up to the harshest conditions—think rocky bottoms, heavy waves, or prolonged sun exposure. Anglers report sharper fish arches with Dual Spectrum CHIRP, revealing schools that traditional sonar misses, while MEGA DI+ excels at mapping weed edges and drop-offs. It's not just equipment; it's the tool that turns good days into limits.

Maintenance Tips to Keep Your Sonar Sharp

• Rinse with fresh water after saltwater trips to prevent corrosion.
• Inspect clamps and cable for wear before each season.
• Avoid high-speed operation with the transducer exposed to minimize damage.
• Store in a cool, dry place during off-season to preserve composite materials.

Simple habits like these ensure years of peak performance, maximizing your investment in premium sonar tech.
