Claims

[Scope of utility model registration request]

In an acoustic sounder that sends out digitized output of sounding values, a gate is opened only when a reflected wave from the correction reflector arrives under the control of the sinking depth measurement circuit of the correction reflector and the output of this measurement circuit. An acoustic depth sounder characterized in that a gate circuit is provided and the output of the gate circuit during verchecking is connected to a water depth measurement circuit so that water depth measurement is performed using a reflected wave from a correction reflector and a transmitted wave.
