Echonautics BT70MA600 series bronze thru-hull CHIRP transducers provide medium CHIRP 80-130kHz depth and temperature performance in a low-profile housing designed to minimize drag and maintain accuracy at high speeds. Matching specific hull deadrise via 0°, 12°, and 18° tilted elements, these 600W RMS units feature 24°–17° beamwidths, urethane acoustic windows, NTC temperature sensors, and 27ft cables for reliable bottom tracking to around 900ft.
