Humminbird XHS-9-HDSI-180T Transducer HD Side Imaging 20' Cable

Overview

Who This Is For: Anglers running dual/HD side imaging on Humminbird systems who need a reliable transom-mount transducer with multi-frequency coverage and real-time temperature data. Whether you're chasing walleye, bass, or panfish, this transducer gives you the sonar flexibility to match different depths and structure types without swapping hardware.

Product Summary: This is a transom-mount transducer built to deliver four distinct frequencies — 20, 60, 180, and 800 kHz — plus HD side imaging all in one unit. The 20' cable gives you reach on larger boats, while built-in temperature sensing adds another layer of intel about where fish are holding. You get photographic-quality side imaging of structure alongside traditional down-imaging and 2D sonar, all from one transducer.

Key Features

• Dual/HD Side Imaging — produces high-definition side-scan sonar showing structure, baitfish, and suspended fish in real time to the left and right of your boat — you see structure and fish location before your traditional sonar even registers them.
• Multi-Frequency Coverage — 20, 60, 180, and 800 kHz all in one transducer — switch frequencies on the fly to match water depth, bottom hardness, and target species without changing hardware.
• 20' Cable with 20/60/180 Degree Coverage — long enough for larger boats and flexible mounting angles — gives you sonar coverage across a wider swing, especially useful when drifting or trolling.
• Built-in Temperature Sensor — tracks water temperature in real time and logs it alongside your sonar data — helps you pattern fish by thermocline breaks and seasonal migrations.
• Transom Mount Design — straightforward bolt-on installation on the back of your boat — no through-hull cutting or in-hull complications; you're on the water faster.

Specs & What's Included

Compatibility: This transducer works with Humminbird fish finders and chartplotters that support dual/HD side imaging and multi-frequency transducers. Verify your sonar unit supports all four frequencies and side imaging before purchase. Not sure if this works with your setup? Call or text us at (833) 831-4077 — we'll tell you straight.

In the Box: Transducer with 20' cable, transom mount bracket, and hardware. Installation and interfacing with your Humminbird sonar unit are your responsibility — no software or control head included.
