Echonautics CB131H1kW 1kW 130-210kHz High CHIRP Bronze Thru-Hull

The Echonautics CB131H1kW 1kW 130-210kHz High CHIRP Bronze Thru-Hull transducer is designed for anglers and boaters seeking detailed structure imaging and reliable performance in both freshwater and saltwater environments. This through-hull mounted sounder provides professional-grade fish-finding capabilities, making it an ideal choice for serious fishermen looking to upgrade their vessel's electronics.

Operating across the 130–210kHz dual-frequency CHIRP range, the Echonautics unit generates 1 kilowatt of power, allowing it to effectively penetrate thermoclines and weedy bottom conditions with minimal signal loss. The bronze through-hull housing is resistant to corrosion from saltwater exposure and ensures excellent acoustic coupling to the hull, providing consistent bottom contact and fish returns even at cruising speeds.

This transducer integrates seamlessly into modern marine GPS/fishfinder systems, revealing underwater structures with clarity and precision. It is particularly beneficial for those targeting suspended fish in deep reservoirs or scanning nearshore structures. Installation requires a properly drilled thru-hull mount with appropriate sealant and backing plate to prevent water intrusion, and professional installation is recommended for optimal performance.
