Portable Echo Sounder with High Sensitive Sensor Water Depth Measuring adopt ultrasonic theory that sonic wave come across barrier then reflect to transducer, according to the time and speed, distance from barrier and transducer can be got. It can detect distance correctly and rapidly when vessel is voyaging. It is usually used in lane survey, under water, terrain survey, vessel orientation etc.
