Fathometer is an echo sounder. An echo sounder is a device for determining the depth of the seabed or detecting objects in water by measuring the time taken for sound echoes to return to the listener. Endoscope– An endoscope is an illuminated optical, typically slender and tubular instrument used to look deep into the body and used in procedures called an endoscopy. Ammeter– An ammeter (from Ampere Meter) is a measuring instrument used to measure the current in a circuit. Anemometer-A n instrument for measuring the speed of the wind, or of any current of gas.
