Humminbird XTM-9-HW-MSI-T MEGA SI+/DI+ Dual Spectrum CHIRP Trolling Motor Transducer w/Temp

The Humminbird XTM-9-HW-MSI-T MEGA SI+/DI+ Dual Spectrum CHIRP Trolling Motor Transducer with Temperature Sensor is a high-performance sonar accessory engineered for anglers who demand advanced imaging and precise water column analysis. This dual-frequency transducer mounts directly to your trolling motor, delivering MEGA Side Imaging+ coverage alongside traditional 2D CHIRP sonar without the need for separate hardware installations.

The transducer operates across multiple frequency bands: 800 kHz and 455 kHz for MEGA Side Imaging+ detail, plus a Dual Spectrum CHIRP range of 150–220 kHz for traditional 2D sonar returns. This frequency diversity allows you to switch between high-resolution side and down-imaging for structure detection and wide-view scanning for suspended fish and bottom contours. The integrated temperature sensor provides real-time water temperature data, critical for seasonal pattern matching and thermocline location. The rugged composite construction withstands saltwater exposure, freshwater corrosion, and impact damage common in active fishing environments. A 20-foot cable connects the transducer to compatible Humminbird units, and the mounting hardware is included for secure trolling motor attachment.

This transducer is designed for anglers running Humminbird MEGA SI+ or DI+ sonar systems who fish structure-heavy waters, offshore environments, or competitive tournament fisheries. It suits both weekend bassers working lakes and serious offshore anglers covering deep water. Trolling motor mounting keeps the transducer stable during slow presentations and eliminates hull-mount installation complexity on boats with difficult mounting locations.

Compatibility verification is essential before purchase—confirm your Humminbird unit supports MEGA SI+/DI+ imaging technology. The XTM-9-HW-MSI-T is not a universal transducer and will not function on standard CHIRP-only or 2D legacy sonar units.
