FIELD: radio-engineering.
SUBSTANCE: hydroacoustic log according to certificate of authorship No (5/09)N1840743 includes, in addition a frequency divider with variable division factor, which is included between key device and inverting input of the counter the "reset" input whereof is connected to the "reset" input of divider, as well as logic switching device of division factor, the inputs of which are connected to outputs of counter, decoder, to inverting input of the counter, and to "transcription" input of decoder, and output - to the control input of frequency divider.
EFFECT: improving measuring accuracy of speed at depths close to depths of switching of log radiation conditions.
