Humminbird XTM 9 SI 180 T Trolling Motor Transducer

Upgrade your fishing setup with the Humminbird XTM 9 SI 180 T, a specialized trolling motor transducer that delivers crystal-clear side imaging and dual sonar performance right from your boat's front lines. Anglers who troll for walleye, bass, or crappie swear by its ability to reveal hidden structures, fish-holding weedlines, and drop-offs without interrupting your cast. Mounted securely on your trolling motor shaft, it scans a massive 180-degree panoramic view to the sides, spotting targets up to 100 feet away depending on conditions, while traditional sonar beams track what's directly below.

Key Performance Specs That Matter on the Water

This transducer combines multiple sonar technologies into one rugged package. It operates on 83/200 kHz frequencies for versatile 2D sonar coverage—think a wide 60-degree beam at 83 kHz for broad searches in shallow water and a precise 20-degree beam at 200 kHz for deeper targeting. The 455 kHz frequency powers the side imaging, creating detailed, photo-like images of the bottom contour and fish positions. With a built-in temperature sensor, you'll also monitor water temps in real-time to dial in on active baitfish zones.

• Mounting Style: Optimized for trolling motor shafts with included hose clamp for quick, vibration-resistant setup.
• Cable Length: 15 feet of durable wiring reaches back to your unit effortlessly.
• Beam Coverage: 20/60 degrees for down sonar, 180 degrees for expansive side scans.
• Bonus: Temperature probe keeps you informed on thermal breaks where predators lurk.

Why Side Imaging Changes Your Fishing Game

Traditional sonar paints a single cone view beneath your boat, but side imaging flips the script. The XTM 9 SI 180 T sends sound pulses sideways, bouncing back high-resolution pictures of the lakebed. Spot isolated rock piles, submerged timber, or schools cruising parallel to your path—details often missed in forward motion. In murky water or heavy cover, where forward-facing sonar struggles, this transducer excels. Pair it with your Humminbird display, and you'll navigate contours like a pro, positioning lures exactly where fish stage.

Built tough for real-world abuse, it withstands splashes, submersion, and the constant flex of a trolling motor in choppy conditions. Anglers report fewer false readings and sharper images compared to older models, thanks to refined transducer elements.

Effortless Trolling Motor Installation

Securing this unit takes minutes. Slide the transducer onto your motor's shaft, tighten the hose clamp, and route the cable along the shaft using zip ties to avoid prop strikes. Aim it parallel to the water surface for optimal side coverage—tilting slightly forward helps in shallow drafts. Test in shallow water before hitting deep structure to fine-tune sensitivity. It's designed to stay put through speed changes, unlike adhesive mounts that loosen over time.

Perfect Match for Side Imaging Fishfinders

Tailored for Humminbird units with side imaging capabilities, like those in the 797c series combos. It unlocks full SI potential on the water, feeding data seamlessly for split-screen views of 2D sonar, down imaging, and side scans. Whether you're jigging vertically or casting crankbaits, this transducer keeps your electronics humming without compatibility headaches.

Tips for Peak Performance and Longevity

To maximize clarity, keep the face clean of algae and debris— a soft brush after each trip does wonders. In winter storage, dry thoroughly to prevent corrosion. Adjust your unit's gain and range settings for water depth; start conservative to avoid clutter from baitfish. For tournament anglers, its reliability shines in multi-day events, holding zero through rough trails.
