This plastic thru-hull NMEA 2000 smart transducer combines precise depth, speed and temperature signals with attitude sensing for heel/trim and pitch/roll data. It can read depths to 330' and offers fast 5 Hz water speed signal output for smoother visualization on compatible chartplotters or other displays. Wireless BLUETOOTH connectivity makes it easy to manage calibration of sensor data through the AIRMAR Cast™ app interface. And the 235 kHz sensor operating frequency helps prevent mutual interference with other echosounder devices on the vessel. The transducer's wide, fan-shaped beamwidth of 10x44 degrees enables it to find bottom even when installed on steep deadrise hulls or heeling sailboats.
