Long-Stem Depth Transducer

Hello,
I would like to connect this Long-Stem
Depth Transducer (see picture) to Arduino and being able to process the read value from the sensor.
Does anyone know what electronic part is required between the sensor (cinch plug) and the arduino?

I have found some info: it is a 150kHz depth transducer used to measure water depth under small boat.

Any help is welcome!
Renaud
