Humminbird XM 9 Transducer MEGA Side Imaging+ Transom Mount

Overview

Who This Is For: Anglers running HELIX 8, 9, 10, or 12 CHIRP MEGA SI+ units who need a reliable transom-mount transducer capable of delivering full MEGA imaging performance. Whether you fish shallow lakes or deep structure, this transducer gives your sonar the hardware it needs to perform.

Product Summary: The XM 9 HW MSI T MEGA Side Imaging+ Transducer is a complete transom-mounted sonar solution that supports MEGA Side Imaging+, MEGA Down Imaging+, and traditional CHIRP 2D sonar. It's built to last with a solid metal bracket and includes everything you need to mount and run — no adapter hunting required. For anglers upgrading or replacing hardware, this transducer unlocks the full potential of your HELIX unit's imaging capabilities.

Key Features

• MEGA Side Imaging+ — produces ultra-high-frequency sonar images at 1075–1150 kHz with 400-foot side-to-side range — you see structure and baitfish in photographic detail, left and right of your boat.
• Dual Spectrum CHIRP 2D Sonar — traditional 2D sonar with three frequency options (Full, Narrow, Wide) covering 150–240 kHz — gives you depth to 1200 feet and clear target separation for suspended fish.
• MEGA Down Imaging+ — high-frequency imaging directly below your boat to 200 feet — critical for sight-fishing shallow cover and reading hard bottoms in crystal-clear water.
• Three frequency tiers — 455 kHz (range/coverage trade-off), 800 kHz (faster response, shallow focus), and 1075–1150 kHz (maximum detail) — pick the right tool for your water conditions.
• Temperature sensor built-in — monitors water temperature in real time — you can dial in seasonal patterns without adding extra hardware.
• Solid metal bracket and 20-foot cable — professional-grade transom mount rated for rough water and long-term durability — bolts on securely and won't vibrate loose.
