Product Description

Echonautics BT87M1KW series 1kW medium CHIRP thru-hull transducers (85-135kHz) deliver superior shallow-water performance and bottom detail with narrow beamwidth for pinpointing fish near reefs and wrecks. Low-profile bronze design minimizes drag for high-speed operation, featuring NTC temperature sensors, urethane acoustic windows, and 30ft cables. Hull-specific tilt angles ensure optimal beam alignment across various deadrise configurations.
