Humminbird XTM 9 DI 25 T Trolling Motor Mount Transducer

The Humminbird XTM 9 DI 25 T Trolling Motor Mount Transducer is a dual-frequency sonar sensor engineered for anglers running compatible Humminbird systems from their trolling motor. This transducer combines Down Imaging and DualBeam Plus technology, delivering both traditional sonar and advanced imaging on a single cable—eliminating the need for multiple transducers and reducing installation complexity on boats where trolling motor mounting is the preferred approach.

Equipped with 75°/45° frequencies at 455/800 kHz for Down Imaging and 25°/16° frequencies at 200/455 kHz for traditional sonar, the XTM 9 covers shallow structure and open water alike. Built-in temperature sensing provides real-time water conditions without a separate probe. The 15-foot cable accommodates standard trolling motor installations, while the low-profile design minimizes snagging on dock pilings and shallow cover. All mounting hardware is included for immediate deployment; installation requires no modifications to your existing motor or boat wiring infrastructure.

This transducer is optimized for weekend anglers and serious tournament fishermen running 700, 500, or 600 Series Humminbird units—particularly anglers who prefer dedicated trolling motor mounting over transom or in-hull alternatives. It works across multiple display models including the 788ci HD DI Combo, 597ci HD DI Combo, 596c HD DI, 587ci HD DI, 581i HD DI, 571 HD DI, 570 DI, and 561 DI. Trolling motor transducers remain powered regardless of main engine status, making them ideal for shallow-water exploration, slow-speed structure work, and situations where main transducer placement isn't practical.

Dual-frequency sonar paired with Down Imaging technology defines modern fish-finding capability. This transducer eliminates the compromise between traditional sonar range and imaging detail, a distinction that separates premium systems from entry-level units in the $400+ price bracket.
