CHIRP Dual-Band Transducers

These transducers function simultaneously in two CHIRP bands, typically Low and High, or Low and Medium.

Not all fishfinders and sounders accept dual-band CHIRP transducers. Check your sonar specifications carefully to determine whether your unit supports dual-band or single-band CHIRP.

Standard Airmar units have bare wire connectors. See the CHIRP Connectors page for brand-specific connection kits.

Dual-band wide-beam and Dual-band ultra-wide-beam transducers are listed on separate pages.
