Echonautics BT70D600 series bronze thru-hull transducers provide dual-frequency 50/200kHz depth and temperature sensing optimized for high-speed performance with minimal drag. Designed for target detail in shallow water and reliable deep-water bottom tracking, these 600W RMS transducers feature urethane acoustic windows, NTC temperature sensors, and 27ft cables. Streamlined bronze housings with hull-specific tilt angles ensure optimal performance across various deadrise angles.
