Bonbo XNT 9 HW T Transom Transducer 20ft Cable

The Bonbo XNT 9 HW T Transom Mount Transducer is a Dual Spectrum CHIRP 2D sonar probe with temperature sensor and 20-foot cable, built to replace or upgrade compatible Humminbird HELIX units for clear fish and structure returns.

Designed for anglers who need dependable 2D sonar from the transom, this Bonbo 710274-1 transducer supports Dual Spectrum CHIRP frequencies across a broad band, delivers deep-range performance to 1,200 ft (365 m), and plugs into a range of Humminbird HELIX models. It includes an impact-release bracket and hardware for straightforward mounting, plus a long cable to reach a variety of boat layouts. Note: this unit provides 2D sonar only and does not offer side or down imaging.

What sonar performance can I expect from the XNT 9 HW T?

This transducer uses Dual Spectrum CHIRP to produce clear 2D returns for fish arches and structure separation across shallow and deep water. The wide-frequency coverage improves target resolution and reduces noise, helping you interpret returns at speed with less turbulence.

• Dual Spectrum CHIRP ranges: Full 150–220 kHz, Narrow 180–240 kHz, Wide 140–200 kHz
• Max depth rating: up to 1,200 ft (365 m) in optimal conditions
• High-frequency beam with broad cone for target detail and coverage
• Designed specifically for crisp 2D sonar returns (no side or down imaging)

Which Humminbird HELIX units will this transducer fit?

The Bonbo XNT 9 HW T is engineered for compatibility with many GPS-equipped and CHIRP-equipped HELIX models. Confirm compatibility with your specific unit series before purchasing to ensure plug-and-play operation.

• Fits HELIX 5 CHIRP G2/G3 (GPS-equipped only)
• Fits HELIX 7 CHIRP G2/G3/G4 (GPS-equipped and CHIRP DI G2)
• Supports HELIX 7/8/9/10/12 CHIRP G2N/G3N/G4N and ICE HELIX CHIRP G2/G3 in open water mode
• Verify model and connector type before installation

How easy is the installation and what hardware is included?

Installation is straightforward: the transducer ships with an impact-release transom bracket and mounting hardware so you can secure it to most transom setups. The 20-foot cable gives installation flexibility for various boat sizes and fishfinder mounting positions.

• Includes impact-release bracket and necessary mounting hardware
• 20 ft (approx. 6.1 m) cable for flexible routing to displays
• Transducer must remain submerged during operation — avoid air pinging
• Bracket provides impact protection and reduces risk of damage

What durability and protection features does it offer?

Built for transom mounting, this Bonbo transducer emphasizes toughness and stability in choppy conditions. The impact-resistant bracket and precision-machined housing provide secure positioning and long-term reliability.

• Transom mount design for rugged support even in rough water
• Impact-release bracket lowers risk of breakage on contact
• High-precision construction for consistent performance over time
• Corrosion-resistant materials suitable for freshwater and many saltwater uses (rinse after saltwater exposure)

Who is this for: The Bonbo XNT 9 HW T is aimed at recreational and serious anglers who use Humminbird HELIX fishfinders and want a reliable, replaceable Dual Spectrum CHIRP 2D transducer with deep-range capability. It suits boat owners needing a durable transom-mounted unit, installers who want an included impact bracket, and fishers who prioritize clear 2D target returns across varied depths. If you require side or down imaging, consider a different transducer type; for high-resolution 2D CHIRP performance and easy transom installation, this model is a strong, cost-effective choice.
