Humminbird XNT 9 SI 180 Transducer Dual Side Imaging Transom Mount

Overview

Who This Is For: Anglers running a Humminbird 797c who want dependable dual and side imaging on their trolling motor without the hassle of a transducer that kicks up in rough water. Built for serious lake and coastal anglers who trust their sonar to find and confirm fish.

Product Summary: The XNT 9 SI 180 is a compact transom-mount transducer that delivers 20/74/84-degree, 200/83/455 kHz imaging with built-in temperature. The redesigned housing sits more securely on your motor and resists kicking up in wave action — a real problem solver if you've dealt with unstable transducers bouncing around in chop. An optional lock-down screw gives you complete control over mounting angle.

Key Features

• Dual and Side Imaging — produces both traditional structure imaging below and angled views to the sides of your boat — you'll see suspended baitfish, weeds, and hard cover in one pass that would take multiple transducers to capture.
• Three Frequency Coverage (200/83/455 kHz) — gives you shallow-water detail, mid-range target separation, and high-frequency clarity — switch frequencies to match water conditions and structure type without changing transducers.
• Improved Mounting Security — redesigned housing resists kicking up when you hit wave action — your sonar stays locked on target instead of losing signal in rough conditions.
• Optional Lock-Down Screw — overrides automatic kick-up protection for complete control of mounting angle — use this when you're running shallow or need a fixed angle regardless of water state.
• Built-In Temperature — displays water temperature in real time — dial in seasonal patterns and thermocline depth without a separate sensor.

Specs & What's Included

Compatibility: Designed for use with Humminbird 797c fish finders. This transducer has the same hole pattern as some older Humminbird transducers, so if you're upgrading an existing setup, check your motor baseplate before ordering.
