Product details

Enhance your HELIX sonar with MEGA imaging on the transom

The Humminbird Transom Transducer is designed to pair with HELIX G3N and G4N units that feature MEGA imaging. Built to withstand the rigors of life on the water, this transom-mount solution includes a built-in temperature sensor and a full 20-foot installation cable, making it easier to upgrade your sonar capabilities without replacing your existing gear.

Crafted for serious anglers and boaters, the transducer combines high-speed performance with clear image quality. The rugged composite housing protects sensitive electronics while a simple mounting process helps you get back to fishing sooner.

What you gain

  • MEGA Side Imaging+ delivers picture-like views up to 400 feet to either side, helping you spot structure and potential fish-holding zones from a wide vantage
  • MEGA Down Imaging+ reveals crisp, high-definition detail up to 200 feet below your hull, improving bottom recognition and cover identification
  • Dual Spectrum CHIRP 2D sonar provides long, well-defined fish arches and a clear view of structure down to 1,200 feet, supporting both shallow and deep-water scouting
  • Built-in temperature sensor helps you monitor water conditions as you navigate and adjust your approach
  • Rugged composite construction and a straightforward transom-mount design suit a variety of boat setups
  • Includes a 20-foot cable for flexible installation and routing options

Real-world use cases

  • Coastal bays and inland lakes where wide-area scanning helps locate submerged structures and schools
  • Deep-water structure scouting and offshore angling where detailed arches and bottom detail matter
  • All-day trips on variable water conditions, maintaining reliable sonar performance on HELIX units

Compatibility and packaging: This transom transducer is engineered for HELIX G3N and G4N models featuring MEGA imaging. It ships as a complete package with the transducer, built-in temperature sensor, rugged housing, and a 20-foot installation cable to streamline setup.
