A pinger device of frequency in the vicinity of 56 kHz and source level of the order of 166 dB, at 1 pPa/m, has been developed for sensing ambient temperatures in the range 5-30Β°C under water. The device uses a thermistor for sensing the temperature which changes the pulse repetition rate of the pin
