Echonautics BT87H1KW series 1kW high CHIRP thru-hull transducers (130-210kHz) are low-profile bronze units designed to minimize drag and maintain performance at high speeds while delivering superior shallow-water performance and detailed bottom tracking. Their narrow 13°–8° beamwidth excels at pinpointing fish tight to reefs, wrecks, and other structure, with NTC temperature sensing, urethane acoustic windows, and 9m (30ft) cables supporting reliable depth and temperature measurements to about 1,000ft.
