Humminbird XTM 9 HW T Trolling Motor Temperature Transducer | Dual Spectrum CHIRP for HELIX

Overview

Meet the Humminbird XTM 9 HW T temperature transducer, a compact, on-motor sonar upgrade that brings Dual Spectrum CHIRP 2D capabilities to your HELIX display. Designed for anglers who move with the water, this transducer mounts to a trolling motor and delivers clear target returns, plus a real-time water temperature readout. Its built-in temperature sensor and generous 15-foot cable keep setup tidy and flexible, helping you stay focused on the scan rather than cables.

Dual Spectrum CHIRP 2D sonar — what it means

Dual Spectrum CHIRP 2D sonar blends a high-frequency beam with a wider cone angle. Practically, you’ll enjoy crisper target returns alongside a broader water-column view, making it easier to spot structures, fish, and drop-offs at a glance. The CHIRP range spans 150–220 kHz, with a max depth of up to 1200 feet, so you can tailor sensitivity and coverage to your water body.

Wide-cone CHIRP made simple means you cover more water while you stay hands-on with your trolling motor, a setup that’s especially helpful when you’re following bait or navigating variable conditions.

• Trolling Motor Transducer: Mounts to your trolling motor to provide Dual Spectrum CHIRP 2D sonar
• Dual Spectrum CHIRP Sonar: Delivers a high-frequency beam and wide cone angle with a CHIRP range of 150–220kHz and max depth of 1200 feet
• 2D Sonar Only: Can be used with Side Imaging or Down Imaging units as a 2D sonar source only
• Fish Finder Compatibility: Works with a wide range of GPS-equipped HELIX G2, G3, and G4 models
• Built-In Temperature Sensor: Includes an integrated temperature sensor and a 15-foot cable

Compatibility and setup

The transducer is designed to integrate with existing HELIX ecosystems, feeding 2D CHIRP information to your compatible display and enabling more informed target interpretation. The built-in temperature sensor adds environmental context directly on the screen, while the 15-foot cable provides flexibility in how you route the unit on a crowded deck or reach high-mlow mounting spots.

• Compatibility: Works with GPS-enabled HELIX G2, G3, and G4 series
• Temperature data: Real-time water temperature at the transducer
• Cable length: 15 feet for flexible routing around the boat

Real-world use and potential benefits

On calm mornings or changing light, the 2D CHIRP returns become easier to read, helping you distinguish structure from open water as you glide along weed lines or drop-offs. In deeper water, the 150–220 kHz range supports improved target separation, while the temperature readout provides quick environmental context that can inform your on-water decisions over the course of a day. This combination is designed to support a versatile fishing routine, from quick scouting runs to longer runs where accurate depth and target clarity matter most.

• Portable integration with existing HELIX setups+
• Flexible CHIRP coverage supports a range of water depths and target scenarios
